What is VoIP…

Basically …

Voice over IP (VoIP) chops-up your voice into small chunks

Sends these small chunks as packets over the Internet (IP).

The far-end plays back the IP packets back into voice.

Some general notes …

VoIP is a widely standardized and well understood technology available for more than 10 years.

The quality of VoIP depends on the compression method (CODEC) and the network conditions.

It ranges from ISDN toll quality to Cell Phone (or worse)

VoIP is past the technology hype today

VoIP is now widely interoperable

What is VoIP…the technology

1. Voice over IP (VoIP) samples 10 – 60ms of voice with an Analog-to-Digital conversion process (CODEC). This is similar to the way the phone company does it today with PCM (Voice over T1/E1).

2. These samples are placed into an IP packet and sent over the network.

3. A far-end device reassembles the voice stream on the other side.

The CODEC: Why is it important?

CODEC - Compression Decompression: Algorithm used to

compress digitized voice to use less network bandwidth. E.g.

G.729, G.723

The CODEC…

Directly determines the bandwidth required

Ranges from 16 to 100 kbs per call

Partially determines the quality of the phone call

Ranges from Toll Quality to Cell phone/GSM quality

The lowest bandwidth isn’t always the best choice

The sound quality is just part of what makes a call sound

good… Network delay and packet loss play a key part in the

voice quality you experience

The more you compress (lower bandwidth) the longer it takes

T.30 Fax T.30 Fax

The Fax tones are terminated in the

gateway, relayed in packet form and

re-modulated at the far end.

+ Uses less bandwidth

+ Is reliability(offers redundancy)

- Is less interoperable

The Fax is carried in a G.711 voice

channel just like a regular phone call.

+ Is interoperability with any gateway

- Uses more bandwidth

- Is less reliability

Signalling Standards Snapshot

Signaling protocols defines how VoIP equipment communicate to

set-up and release telephone calls over IP networks.

For example – Ring, Talk and Hang-up.

H.323

The first multimedia over IP protocol

Peer-to-peer, defined by the ITU, current Version is v4

Offers high interoperability between 3rd party equipment.

SIP

The newest of the VoIP call control protocols

Peer-to-peer, defined by IETF, looks like html, most extendable

Supported in SmartWare since Release 3.00

MGCP

Master-Slave protocol for centralized Softswitch Carrier architectures

Various forms NCS (Cable), H.248, Megaco

MGCP/IUA is supported in SmartWare for BRI Interfaces

overprovisioning

• In the Access and WAN Bandwidt is expensive and must be used

optimally

major contribution to end-to-end delay.

QoS and VoIP: What's the Problem (1)

QoS and VoIP: What's the Problem (2)

Packet Loss through Queue overflow

Access Link LAN Backbone

• All network equipment has limited queues

• Data traffic (TCP) will always try to get maximum throughput

• Queues should be short for real-time (voice) traffic

• Packet loss is NOT critical for Data (TCP) traffic

Example Measurement with one VoIP call and a FTP download

over a best-effort 500k Link.

QoS und VoIP: What’s the Problem (3)

About 25% of the voice packets are lost at the access to the

Bottleneck!

QoS Standards

DownStreamQoS™

• Where is the Problem

• Solution

• How does it Work

• FAQ

Problem

• The Internet and many large IP networks only

support best effort packet forwarding.

• There is no differentiation between time critical IP

packets such as VoIP and other traffic such as web

pages mail etc.

• If an overload situation occurs (at the network

bottleneck) VoIP and other packets are discarded

with the same probability.

• This leads to a degradation in voice quality while

other traffic is simply retransmitted and the user

just experiences a slow-down

Access Link Internet

Web

Server

VoIP

Edge Router CPE

Solution

• The network bottleneck is in most cases the subscriber

access line DSL, Cable etc of ~< 2 Mb/s

• Both LANs (10/100 Ethernet) and Backbone Networks

(Fibre, SDH or ATM) are much Faster

• In case of congestion packets are discarded at the

Edge router of the Internet access provider (see

previous slide)

• SmartNode DownStreamQoS™ introduces a dynamic

virtual bottleneck at the customer premises that starts

to discard non-realtime traffic before it starts to block

the voice traffic in the edge router “Virtual Bottleneck”

Internet

Web

Server

VoIP

Edge Router

How Does it Work

• Most Data traffic (~80%) is sent using the TCP

protocol.

• TCP continuously increases the used bandwidth

(slow-start) until the maximum throughput is

reached and packets are dropped (not

acknowledged by remote end)

• A separate queue for TCP makes it possible to delay

and if required discard traffic before the access link

is full

• The traffic management (scheduler) for this queue

is adapted dynamically based on the bandwidth

required for voice calls

The integration of QoS Router and VoIP Gateway makes things

much easier

• Traffic Classes are defined at network interfaces

• No tagging necessary for point-to-point links

• Optimal bandwidth usage and control

The Elevator Story…Telephony over IP

The SmartNode ToIP products allow you…

“...to deploy telephony services over any

IP network including the Internet”

“... make VoIP technology transparent to

the end-user in terms of voice quality

and usability.”

“... enable users of Patton’s ToIP to

save costs and grow services while being

flexible and cost effective.“

What is Telephony over IP?

ToIP takes Voice over IP and makes it useful by

providing transparent and low-cost telephony.

Telephony over IP provides incentives for End-Users, Network

Administrators and Service Providers. For instance…

End-Users can reduce their long-distance and international phone

bills without changing their calling behavior

Network administrators can reduce their infrastructure costs by

converging Telephony and Data services in a single network

Service providers can add lucrative telephony services to their

offering without building up a separate network

Providing an easy to use and install Telephony service using

VoIP technology requires.
