Reduced Circuit Costs

Reduced Plant Costs

Reduced RAN Costs

Reduced Cust. Service Costs

11www.ellacoya.com

Circuit Costs

Management of P2P traffic has a substantial impact on backbone bandwidth

Reduce upstream utilization by up to 50% without generating a single subscriber complaint

Defer expensive circuit upgrades

Before Ellacoya: 700 Mbps

After Ellacoya: 450 Mbps

12www.ellacoya.com

Plant Costs

Congestion can be as expensive as circuit congestion

Aggregate P2P management cannot solve this problem

Per-IP management of upstream P2P reduces congestion

Defer and reduce plant upgrade expenses including: Splitting / de-combining nodes Adding DWDM

Before Ellacoya: 8 Mbps

After Ellacoya: 5 Mbps

13www.ellacoya.com

RAN Costs

Congestion causes increased CPU utilization on routers

Capacity Management addresses congestion in RAN

Defer and Reduce expenses including: Router CPU, Memory upgrades Line cards Forklift router upgrades

Before Ellacoya: 75% CPU

After Ellacoya: 64% CPU

Customer Support Costs

Congestion impacts subscribers’ experience Increases in Customer Support call costs Increased churn

Ellacoya management has a dramatic effect on volume of complaints about slow web browsing Reduce OPEX, reduce churn, increase subscriber satisfaction

Prioritizing Applications

17www.ellacoya.com

Dynamic Rate Limits Allows subscribers to burst their traffic when the network is uncongested

No rate limits when network traffic is light:

( e.g.) 300Mbps threshold

Total traffic on GE link less than threshold

Enforce Rate Limits when network gets congested:

Total Upstream P2PRATE LIMITED to

(e.g.) 20Mbps( e.g.) 300Mbps threshold

Total traffic on GE link greater than threshold

P2P Rate limit (e.g.) 20Mbps is not

Classic PCMM Model

One AM to integrate per content/application source Security/authentication/encryption

Application manager is usually server hosted Subscriber authentication under ASP control

Does not work with peer to peer applications, for example: Gaming consoles PC games Some forms of VoIP Video conferencing Home surveillance … and many more

22www.ellacoya.com

Distributed Application Manager

Ellacoya Multimedia Service Manager (MSM) Distributed deep packet inspection AM

– In each switch, with the capability to recognize all applications Leverages subscriber and application awareness Activates QoS for subs part of specific service tiers

MSO benefits of MSM No need to integrate third party AMs into the PCMM network Puts AM function under MSO’s control

– MSO owns direct subscriber relationship Works with all applications: server-based and peer to peer

Allows Operators to increase revenue immediately Simplifies the roll-out of PCMM-based applications Removes the need for cable-specific AMs for each application Works with any application

Puts authentication and authorization back in the Operator’s hands No third party AM integration required Entire PCMM infrastructure is owned and operated by the Operator Helps MSO further build direct relationship with the subscribers

Based on proven \ technology Deployed in cable networks worldwide since 2002
