Student Notes







Latin America is a region that has great variation in the types of mobile network, and

because of this fact usage varies greatly from country to country. Most networks in the

region are 2G/3G networks, however with the rollout of LTE in some countries, mobile

networks have begun to offer an experience that is equivalent and in some cases evenbetter than that of fixed access networks in the region.

For this report, we observed a mean monthly usage of 355.8 MB, a modest increase over the

344.1 MB we observed a year ago. It should be made clear however that there is wide

variation in usage from country to country and network to network. For example, in one

Latin America country we observed mean monthly usage on a 3G network to be 343MB,

while on an LTE network in the same country it was 2.7GB. This wide disparity means that

operators, particularly those in emerging markets with low fixed access penetration, should

prepare themselves for drastic changes in the usage of their subscribers as subscribers are

sure to take full advantage of the speed and quality of experience benefits provided by

LTE.





For full explanation of this infographic, see Page 20 of the 1H 2013 Global InternetPhenomena Report

At Sandvine, we’ve long argued that implementing UBB would likely have minimal (if any)impact on network congestion and subscriber quality of experience (QoE) during peak, assubscribers are unlikely to stop using their favorite applications during the peak eveninghours. CSPs that are actually seeking to manage network congestion need to put effectivetraffic management mechanisms in place in order to proactively ensure high subscriber QoEfor real-time sensitive applications during peak hours.

What stands out most clearly is the fact that Real-Time Entertainment’s traffic share isalmost identical on both UBB and non-UBB networks, demonstrating that high bandwidthstreaming audio and video traffic is of such high value to all subscribers that they areunwilling to stop or alter the way the consume it even though they have a cap placed on

their monthly usage.

What is also interesting is how much lower a share Filesharing traffic has on networks withUBB compared to those who do not have it. This demonstrates that subscribers may bemindfully limiting their use of Filesharing applications, which often generate traffic in boththe upstream and downstream direction. Additionally, aside from being a good peer (whichis likely of little importance to occasional Filesharing users), there is little direct benefit touploading content, so that might well be the first activity that is stopped. It may even bepossible that Real-Time Entertainment has a slightly higher share on networks with UBB duein part to the fact subscribers are getting more of their content via Real-TimeEntertainments sources which are typically more efficient (if you consider the valueproposition to be “equal entertainment for less aggregate usage”) than Filesharing, since

there is relatively little upstream traffic associated with streaming.





Interestingly, while we observed YouTube making some inroads on fixed access networks,

we have begun to observe Netflix gaining more and more momentum on mobile networks.

While watching a full length movie, or a 22 minute sitcom, on a 4-inch smartphone screen

may not be the ideal viewing experience for everyone, for many subscribers it is becoming aviable experience. Netflix’s downstream traffic share in North America almost doubled

from 2.2% to 4.0% in just 12 months time, and we believe that that this number will

increase going forward and that longer form video as a whole will become more

commonplace on mobile networks in North America.





In our 1H 2012 report, we revealed that Real-Time Entertainment applications on mobile

devices (smartphone and tablets) accounted for 9% of all fixed network traffic in North

America and in our last report we predicted that by 2015, the phenomena will be even

more profound, with mobile devices accounting for 20% of all traffic on North Americanfixed access networks.

It turns out 2015 came a little early, and based on data collected smartphones and tablets

now account for 20% of total traffic. This rapid growth is due in large part to the rapid

adoption rates of larger screen devices such as tablets and the growing number of Real-

Time Entertainment sources offering higher resolution video.

Home Roaming is an enormous contributor to Real-Time Entertainment traffic consumption

and as mentioned a cause for its growth, with over 25% of all streaming audio and video

bytes being delivered to mobile devices being used in the home.





So what single home roaming device consumes the most Real-Time Entertainment traffic at

over 10%? It’s the iPad. In fact, Apple devices as a whole play a large role in the

consumption of Real-Time Entertainment. If you add up all Apple manufactured devices

(which includes iPads, iPhones, iPods, AppleTVs, and Mac computers), they consume over35% of all streaming audio and video on North America fixed access networks.





Based on data from a tier-1 European network, approximately ten WhatsApp messages are

sent and received per subscriber each day. Of these messages, 2.8% of all messages sent

have a media file such as a photo or video attached.

For mobile operators, this type of insight allows them to better understand the impact

these messaging applications are having on their bottom line, and better craft service plans

that meet the changing demands of subscribers.





What traffic will fixed networks in the United States be carrying in the future? It’s always

both fun and informative to take a look, and we’ve done so again in Figure 10. These

projections have been revised using 1H2013 data and are based on a bottom-up analysis of

measured household traffic profiles, observed traffic trends, and a number of informedassumptions:

-Home roaming will play a prominent role in fixed access network profiles, (currently it

accounts for 20% of traffic)

-Legal streaming sites and services from Netflix, Amazon, HBO, and the major sporting

leagues will remain active and well-stocked with compelling content

-Filesharing, while slowly declining in share, is here to stay, even if only within a dedicated

community and as a legal distribution mechanism for content such as software upodates

What emerged is a future in which:

-Real-Time Entertainment applications dominate fixed access networks,accounting for two-thirds of total data usage in 2018, driven largely by ubiquitous

integration between devices (e.g. smart TVs, set-tops, game consoles) and streaming

services

-Web Browsing will continue be the second-largest source of traffic, partly

driven by the number of mobile devices at use in the home

-Tunneling traffic will become a major player in the traffic mix as more

critical and privacy senstive applications go online (security cameras, banking) and as

subscribers seek ways to protect their identity online and access content restricted to them

because of their geographic location





What traffic will mobile networks in the United States be carrying in the future? It’s always

both fun and informative to take a look, and we’ve done so again in Figure 5. These

projections have been revised for this report and are based on a bottom-up analysis of

measured traffic profiles, observed traffic trends, device usage characteristics, devicemarket share, and a number of informed assumptions:

-The vast majority of tablet traffic will not be carried on mobile networks

-Smartphone market share will continue to grow, but feature phones will continue to make

up a significant part of the North American subscriber base

-Machine-to-Machine traffic will slowly, but eventually, emerge (but much slower than

many are predicting)

-Home roaming, the concept of subscribers voluntarily offloading mobile traffic onto Wi-Fi

networks is a very real phenomena

After finishing all of the number-crunching, a number of interesting projections appear:

-Video and audio streaming applications will account for over 60% of mobile usage by 2018

-Web Browsing, including traffic generated by mobile applications will continue to make up

a significant portion of the network

-Social Networking will account for more traffic than we had previously predicted, thanks to

adoption of tiered service plans which allow users to purchase low cost data plans that give

them access to the social applications they value most.










































































Sandvine is the unifying platform for network policy control in fixed and mobile broadband

networks.

Network Business Intelligence provides actionable data required by service providers to

maximize the value of their networks. Network policies implement the desired actions,

enabling Traffic Optimization, Service Creation, and Operations Management solutions in a

transparent manner, improving Subscriber Quality of Experience.






Traffic Optimization is a solution suite that enables the most flexible approaches to achieve network

efficiency for DSL, Wireless and Cable service providers who must assure subscriber satisfaction when

their networks are strained by fast bandwidth consumption and application growth.

Sandvine’s Service Creation suite - enables a host of offerings including:

• Access Service Solutions - Bandwidth Tier Management enables the creation of customizedbroadband access service plans that can be defined by a number of individual network usagepatterns.

• On-Demand Services - enable instant, subscriber-controlled access to content-rich services.

• Advanced Services - ensure optimal quality of service (QoS) for next-generation rich- contentand application services.

• Business intelligence - Network Demographics provides valuable insight, encompassingtraditional network metrics, featuring subscriber and application-awareness at all levels ofthe organization.

Operations Management - Operations Management supports QoE analysis for applications like Web

browsing and VoIP. This is a tool that can proactively measure VoIP quality trends, essential to secure

customers. Sandvine offers a comprehensive set of quality metrics including:• VoIP Mean Opinion Scores (MOS)

• call jitter

• call delay

• and call packet loss.

Using Sandvine’s Network Demographics reporting, service providers can visually identify network

problems before subscribers notice any impact on their VoIP call quality.

Business intelligence - Network Demographics provides valuable insight, encompassing traditional

network metrics, featuring subscriber and application-awareness at all levels of the organization.






Sandvine policy management solutions are deployed on a single intelligent platform to

simplify the network architecture and ensure a fast return on investment.

Service providers today are focusing on policy management solutions to differentiate and

protect their IP service offering. This critical technology must be easily deployed

throughout the network and delivered reliably for today’s demanding subscribers. Sandvine

has recognized these important requirements with the introduction of 10 GE interfaces,

scalable performance with the largest network deployment base of 240 Gbps and an

innovative approach to transparently handle asymmetry in large tier-one networks.

Sandvine Policy Traffic Switch (PTS) portfolio helps service providers to better profit from

application traffic. Our policy management solutions address key challenges such as:

• managing bandwidth-intensive traffic

• controlling malicious threats

• enabling new services

• and identifying application quality trends.






The Sandvine Storage, Reporting and Policy platform (or SRP 3000) is a fault tolerant, high

capacity database server for use in large-scale networks. The high capacity, high speed disk

drives in the SRP 3000 support the large table sizes and fast insertion rates required for

centralized data storage typically required on these type of networks. The SRP offers theproven reliability needed for both application reporting and per-subscriber services. The

SRP typically functions as a Subscriber Policy Broker (or SPB) server, and it is usually

deployed on the management network.

The Sandvine Service Delivery Engine (SDE), is a service delivery solution for launching next

generation services across a converged network infrastructure. The SDE provides end-to-end

resource management and control that ensures predictable performance across the core

and access network.

Sandvine’s Control Center gives service providers the ability to manage policy throughoutthe Sandvine network from a single location with their graphical user interface application.

It offers intuitive navigation with all the conveniences of interactive setup wizards, policy

templates, drag ‘n drop modifications and display window resizing.

The Sandvine Network Analytics product consists of server and software components that

gather information from data sources. It organizes and creates relationships within the

information, and presents the information in a form that facilitates critical business

decision making.





The Sandbox is filled with answers! Whether the question is about something as simple

product configuration, an broad as industry trends, or as specific as to how to write a

SandScript procedure to perform a custom measurement on the network, Sandvine’s experts

(and product experts at our customers!) are there to discuss and provide the answer.










The following table provides performance metrics under typical network conditions. Actual inspection

throughput performance may vary based upon the software licenses and policies enabled, and

deployment characteristics.










The PTS 22000 has fixed ports and one slot that can be used for Ethernet interface blade or any of the

two bypass blades for power failures and major system events.






Remember that throughput and subscriber count are likely the prime scaling concerns –

mobile data providers care more about subscriber count.

Also, don’t forget the whole PTS portfolio – Sandvine has a PTS solution for networks of any

size






Note that you can install two 40 Gbps blades, but you must be intersecting lines with <= 60

Gbps aggregate throughput.






• Actual inspection throughput performance will vary based upon the software

licenses, enabled policies, and deployment characteristics.

*Note on clustering:

• The 8 Tbps is based on a theoretically possible cluster (in that the hardware

theoretically allows this) of 45 units

• Racking a PTS 32000 requires a space above, so each actually consumes 3 RU of

space; hence, only 6 can be deployed in a rack

• Ceiling (45/6) = 8.

Remember that throughput and subscriber count are likely the prime scaling concerns –

mobile data providers care more about subscriber count.






Notes:

• the 8x10GE ports on the left are actually 8xSFP+, so they can be 10GE or 1GE

• 60 10GE ports = 8 (on the left) + 16 Data (4x10GE for each of the four 40GE Data

ports, by way of breakout cables) + 36 Cluster/Service (by way of breakout cables

on each of the 9 40GE interfaces on the right)





Policy Traffic Switch:

• Embedding Intelligence in the Data Plane supporting the world’s largest

deployments

• Inspection up to 8 Tbps, 60 million new flows per second and 2.4 billion concurrent

flows





The Sandvine Policy Traffic Switch portfolio helps service providers to address key businesschallenges. Whether the provider is operating in an emerging market where sustainablegrowth is the primary issue or fighting in a competitive landscape where rapid innovation isthe key to success, the PTS is the platform that can take the network to the next level.

PTS 22000 - Delivers edge service scalability with 8 x 1/10 GE links and a novel approach tohandling asymmetric routing. The PTS 22000 allows:

• insight into and management of traffic at bandwidth levels and network scale

• clustering capabilities enables up to 4 unit, 80 Gbps intelligent traffic management.

• Clustering technology allows true N:N+1 redundancy.

The PTS 22000 is available in a 20 Gbps model suitable for medium POPs and service edgedeployments.

PTS 24000 - The third generation in the Policy Traffic Switch portfolio, Sandvine has againset the standard for scalability, flexibility, reliability, and functionality. Available in four

models:

• 24700 (160 Gbps)

• 24500 (80 Gbps)

• 24300 (40 Gbps)

• 24100 (27 Gbps)

• 40 Gbps or 60 Gbps per-box throughput with clustering to solution deployments ofup to 360 Gbps

The PTS 24000 ensures that service providers can apply network policy control and enablenew services. These advances are achieved on a modular platform delivering a unique fan-in/fan-out architecture allowing multiple 1/10 GE in and 10 GE out data intersects and

industry-leading port density.






We will now take a look at a high level, logical overview of the inline deployment and thefeatures provided by it. This deployment is explained in more detail later in the course.

• Inline deployment. The PTS system can be deployed it is located in-betweencommunicating network devices and intersects the data flow. This deploymentmode offers the full range of features and functionality, including reporting, policyenforcement or traffic management.

• Offline monitoring. This is where the PTS does not sit in the path of the data flowand is merely provided a copy of the data passing between the communicatingnetwork devices. This is a specialized configuration and does not offer fullfunctionality; It is however, the deployment option new customers typically selectuntil they wish to implement the full suite of features.

From the above diagram you can see a typical placement of a PTS sitting inline on anetwork. The PTS is allocated IP addresses on management ports, which are also called therouted interface or the control interface.

The control interface is used to communicate with the PTS. The two data ports are inpromiscuous mode and do not have an IP address. Hence, PTS is seamless to the routers oneither side of the connection.

Subscriber data is switched through the PTS. Data enters one data intersect port and exitson another. Data intersect ports are not assigned any IP addresses. With respect tosubscriber data, PTS acts as a layer 2 device. The IP address on a PTS is used for

management and clustering.






We will now explain the logical data flow. This consists of each PTS having several

processing modules, each running a Policy Traffic Switch Module (or PTSM) and Policy

Traffic Switch Daemon (or PTSd).

In this simple diagram we will show how the data flow enters the PTS and passes through a

Network Processing Unit (or NPU) which performs load balancing, and reliably directs a

given flow to a particular module maintaining state.

The PPU (Packet Processing Unit) module processes the flow and returns it to the NPU

noting how to handle it.

• PTSM is the kernel bridging module inside the PTS unit. It is responsible for

receiving the data packets, processing them and sending them out of the other data

interface.

• PTSd is an application which delivers instructions to the PTSM (the kernel module

that processes traffic). PTSd is the daemon that holds or enforces the rules

specified for processing the incoming traffic. Before the PTSd can be enabled, the

PTS must have the appropriate license installed. PTSd requires PTSM to run.

All Policy Enforcement is done over the data ports.






In this more detailed example of the data flow, and for the sake of brevity, it shows two modules ofan PTS. A cluster will consist of many more, but the logical flow will still be the same as shown here.As the data enters the NPU it looks at the source address before passing the data into the switchingfabric, where it is distributed evenly between available modules.

The PTSM bridges the data and passes it onto the PTSd. The PTSd "runs policy" on each flow anddecides which policy "actions“ apply to each flow. It then sends a list of policy actions to the PTSmfor each flow. The PTSm blindly executes those actions (count, shape, etc). The PTSd application isresponsible for processing the data and carries out these functions:

• Deep Packet Inspection - which Identifies the different types of traffic that are beinguploaded and downloaded by the service provider subscribers at OSI Layers 3 through 7

• Counting - which can be used to record the rate of bits per second or Total Bytes transferredover a period of time. This data is recorded per interface, application, protocol, orsubscriber (as configured).

• Policy Enforcement - which allows the service provider to "do any action under any

condition".• Traffic Shaping - This controls uploads and downloads from and to the service provider

subscribers. It can be used to effectively manage the distribution of bandwidth amongvarious service classes in a service provider's network.

• Per-subscriber Statistics Collection - can be used for detailed traffic analysis for somespecific users.

• Network Protection Monitoring - which monitors the network for malicious traffic andenables ISPs to create rules to identify and mitigate malicious traffic. In effect, it monitorstraffic (packets) for "events" in a detection window.

Once the data has been processed by the module it is passed back into the switching fabric where it isdirected back into the NPU for destination routing and onward transmission.






• Additional capacity - Ease of scalability; a series of Virtual Switch Clusters (VSC)

using direct 10 GE links deliver up to 480 Gbps performance by adding PTS 24000

units to the cluster. Alternatively, for you could deliver up to 240 Gbps

performance, by using PTS 22000 units in the cluster. And now with the PTS 32000you can cluster theoretically up to 8 Tbps.

• Asymmetric traffic handling - The ability for diversely routed traffic to be

managed transparently and recombined for accurate stateful inspection, without

the need for any network changes.

• Auto-Load Balancing - The Virtual Switch Cluster requires no manual intervention

to determine failure and will re-distribute its load amongst the remaining units in

the cluster instantly upon detection of failure.

• N:N+1 redundancy - N+1 redundancy is a form of resilience that ensures system

availability in the event of component failure. Components (N) have at least one

independent backup component (N+1).






PTS's are directly connected to each other via cluster ports eliminating the need to

provision additional ports for the deployment.

An simple example of a dual PTS cluster connection is shown in the previous slide where

both the PTS 14000 pair and the PTS 24000 pair are connected to each other individually by

one cluster link cable respectively.

Each PTS provides multiple cluster ports allowing units to be clustered in a ring or mesh

topology (Mesh is recommended)

Cluster ports can be Link Aggregated allowing two or more cluster ports to be seen as a

single, unified data channel.






The Sandvine Storage, Reporting and Policy platform (or SRP 3000) is a fault tolerant, high

capacity database server for use in large-scale networks. The high capacity, high speed disk

drives in the SRP 3000 supports the collection of large volumes of data on today's networks.

The SRP offers the proven reliability needed for both application reporting and per-subscriber statistics. The SRP typically functions as a Subscriber Policy Broker (or SPB)

server, and it is usually deployed on the management network.

The network-wide collection of application, subscriber statistics may require hundreds of

gigabytes or even terabytes of data every month.

SRP 3000 servers provide the capacity, performance and reliability needed for this high

volume of data and enable Sandvine’s advanced Network Demographics reporting and

centralized subscriber policy management.






Sandvine also offers the SRP 3000-lite to meet the storage and reporting requirements of

smaller networks. The SRP 3000-lite provides the same key SRP 3000 fault tolerant features

along with two hard drives in a mirrored configuration. This platform is also ideally suited

as an application server for large service providers wanting to optimize their criticalmiddleware tier with specialized database and application servers.





The dimensions of the chassis are as follows:

• It comprises of a 2 Rack Units (RU) chassis which is 17.4 inches wide by 3.5 inches

high, with a depth of 24.8 inches.

• The unit weight is 25kg or 55lbs.

• The mounting is a standard 19-inch rack using front mountable brackets

• The input Power is:

• 100-240Volts AC

• Current is 6.5-2.7A (For AC chassis) and 15.4-11A (For DC chassis)

• A fully loaded system draws up to 500 Watts

• The DC version requiring between -42 and -60Volts DC






In this diagram you can see the hard disk drive distribution for the SRP 3000D-14TB, SRP

3000D-6TB and SRP 3000D-lite.






The Sandvine SRP 3000 is a hardware platform that can be deployed into a network to

function as a Subscriber Policy Broker (SPB) server.

The data housed by the SPB enables new subscriber services by leveraging the complete

network characterization.

The SPB integrates with existing provider systems.

Subscriber identification option via DHCP, RADIUS or OSS integration. The subscriber

identification functionality is available either through integration with the service

provider’s operational support systems (OSS) using industry-standard APIs or discovered

passively during DHCP or RADIUS protocol negotiations.





Control Center is Sandvine’s unified policy and operations management graphical user

interface, providing a single mechanism for monitoring operational information, editing

network policies, configuring elements and deploying network policy control solutions.

Control Center allows you to safely configure your policy in isolation from the physical devices in

order to control when new policy behavior is enforced. All policy and configuration changes are

maintained in Control Center's database, called the configuration environment, and only pushed to

the elements, called the production environment, through the Deployment action.





The GUI consists of four primary operational “windows”:

• Menu and Toolbar: Refresh, save, deploy and snapshot, auto-refresh

• Tasks tabs: Placed in the order that best represented work flow; Solutions,

Operations, Policy, Configuration and Task History (auditing)

• Alarm Counts: Displays the total number of active alarms of each severity across the

Communications Service Provider (CSP).

• Navigator pane:

• Network, cluster, datahome and element browser

• Clusters are highlighted

• Issues (i.e. Policy mismatch between node/element and Control Center)\

• Stylized icons for PTS, SDE and SPB

• Clusters icons show two small boxes below the icon to indicate a cluster.

• Datahomes represented by DB icon

• Work Pane: Display details relevant to the element/cluster and function tab. You

see only what you should see, based on the element selected.

• Updates & Notifications widow: Displays the available updates for the Control

Center client.





Sandvine Network Demographics Reporting is the powerful reporting function of Sandvine’s

overall Network Policy Control solution.

Sandvine’s Policy Traffic Switch (PTS) platforms and associated licensed software products

collect network activity data and store it on the Subscriber Policy Broker (SPB) database.

The Network Demographics can use this data to generate hundreds of different reports that

provide complete visibility into application and subscriber traffic for providers of all sizes,

including the largest tier-1 networks.





The Network Demographics reports can provide real-time, actionable data in meaningfulterms, including visual and data reports on the amount of:

• E-mails

• Voice over Internet Protocol (VoIP) minutes• Peer-to-Peer (P2P) file-sharing by protocol/user

• and an array of other networking topics.

There are three Main Modules available through the Network Demographics feature andthese are:

• Resource Monitoring

• Network Characterization (including Network Integrity)

• Subscriber Analysis

Reports can be used to identify subscriber usage patterns to gain a better understanding of

subscriber reality.

Reports can be generated for all elements that log to the same database (SPB).

Reports are viewed in a browser and can be saved, printed, bookmarked for futurereference, and distributed via e-mail. Sandvine provides a number of standardized reportssuch as Peer-to-Peer connections, per-subscriber statistics and bandwidth by protocol.Advanced features are available to custom-build reports based on standardized reports.

Network Demographics allows the user to automatically schedule the generation and

distribution of these reports via e-mail.





Network Analytics delivers network-wide visibility into traffic and operating conditions that

enables you to make better informed decisions about subscriber plans and capacity

planning.

It simplifies and automates the process of extracting and presenting useful data, includingmetrics, projections, and reports. Using the reports to detect network problems and

anomalies enables you to respond faster to developing trends.

The Network Analytics product consists of server and software components that gather

information from data sources. It organizes and creates relationships within the

information, and presents the information in a form that facilitates critical business

decision making. It is designed for the emerging field of subscriber data management, and

is deployed on both Sandvine's Policy Traffic Switch (PTS) platform and a third party server

platform.

It consists of the Network Business Intelligence (NBI) NBI_Base Policy package which is

loaded on to the PTS to collect the detailed stats. The rest of the product package is

installed on a standard RedHat server which extracts data from the Sandvine Policy Broker

(SPB) and the Service Delivery Engine (SDE, for Traffic Management and Real-Time

Entertainment Dashboard deployments).

Fairshare (Fs) for Cable Networks, part of the Traffic Management (TM) product family,

enables service providers to manage congestion in cable access networks.

Fairshare deploys the Service Delivery Engine (SDE) and Policy Traffic Switch (PTS)

platforms to create and implement optimal congestion management policies. Because the

SDE is tightly integrated with the PTS, as well as with IPDR, PCMM and SNMP interfaces on

the Cable Modem Termination System (CMTS), both a highly granular level of visibility into

the network and flexible upstream and downstream enforcement options are made

possible.





Fairshare for Cable Networks, part of the Traffic Management product family, enables

service providers to manage congestion in cable access networks in a truly novel manner.

1. a: IPDR records are streamed from CMTS to IPDR collector

b: SDE performs SNMP polling to measure congestionc: PTS policy classifies traffic according to fairshare_cable package configuration

2. Fairshare rules evaluated every 15 minutes; Identified heavy users receive Fairshare

actions

3. a: PCMM gate forwarded to CMTS

b: Subscriber attribute set to “true” through SPB API

Subscriber usage can be collected from the CMTS using either of these supported standards

and protocols:

Supported standards and protocols:

• Fairshare for Cable Networks supports:

• DOCSIS 1.x, 2.0, 3.0

• PCMM I01, I02, I03

• IPDR transport: IPDR/SP 2.2; XDR 3.5

Sandvine’s Fairshare helps service providers mitigate these challenges. It manages

congestion in networks and thereby improves subscriber QoE and defers infrastructure

upgrades. As a result, infrastructure lifetime is extended and costs for operators is reduced.

Fairshare is a reporting and congestion management product for 3G, 3G-transitional, DSL,

cable, and LTE networks.





Cable: Fairshare is deployed on the Sandvine Policy Traffic Switch (PTS) and Service

Delivery Engine (SDE) platforms. Policy decisions are based on usage data collected at the

PTS, as well as data from the SDE’s IPDR interface (for both DOCSIS 3.0 and earlier

implementations). Most effectively, the PTS performs downstream traffic management,while the SDE signals upstream policies to the CMTS via PCMM. Users are mapped to the

network topology to enforce congestion-sensitive policies and to provide detailed, valuable

reporting of both usage and policies per network resource.

DSL, FTTH, Mobile and Fixed/Nomadic Wireless: Fairshare works with an inline Sandvine PTS

to monitor usage and apply policy via traffic marking or mirroring the network topology in

the PTS and managing virtual links according to congestion conditions. Congestion can be

managed according to specific congestion thresholds, subscriber characteristics (e.g. tier,

device, heavy usage) and/or applications in use on a per virtual link basis.









Sandvine’s Fairshare for Mobile Networks helps service providers mitigate these challenges.

It manages congestion in mobile networks and thereby improves subscriber QoE and defers

infrastructure upgrades. As a result, infrastructure lifetime is extended and costs for

operators is reduced.

Fairshare for mobile networks is a reporting and congestion management product for 3G and

3G-transitional networks, such as HSPA, HSDPA, HSUPA, HSPA+ operators.





These solutions might lead to lowering subscriber QoE by affecting subscribers even when

there is no congestion, restricting them from using the available bandwidth. This is because

the sum of the enforcement policies in these solutions may be less than what is required to

relieve congestion. For example, there may be congestion in a network even when thereare few or no heavy users, or less or no low-priority traffic.

During times of congestion (especially in mobile networks), packet-queuing to avoid packet

drops causes significant amount of latency for subscribers. This has a negative impact on

real-time and interactive applications, such as VoIP and gaming, which are more sensitive

to latency than to packet drops. For these applications, dropping a packet may result in

increased throughput and increased QoE. For example, video streaming drops can cause the

provider to downgrade the bitrate of the video, whereas high latency can lead to increased

jitter.

To complicate the congestion problem further, drops that occur downstream in the network

are usually not performed in a subscriber- or application-aware manner, which means

congestion impacts all subscribers and applications. For example, if a significant amount of

traffic is bulk transfers, then this traffic can make a cell unable to provide a fast Web

experience.





Fairshare’ goal is to create capacity on congested access resources by dividing traffic into

high-value and low-value categories and then shaping low-value traffic at times of

congestion.

High-value traffic

• Real-time applications

• Majority of users (95%)

Low-value traffic

• Non-real-time applications

• Short-term heavy users (5%)
