BP503 : What Does it Do to the Network? Answering Question #1 for IBM Sametime 9 Video

Peter Lurie, Polycom

Agenda

Introduction

Level Setting – a Glossary of Video-Specific Terms

Sametime Call Types– Point to Point– Multipoint– Mobile

Doing the Math– What Happens When Things Go Wrong?– What Helps When Things Go Wrong ?

• QOS, LPR, SAC, etc

Wrap-up and Q&A

Abstract

Sametime 9 has made tremendous improvements in the audio and video capabilities. Organizations are piloting and now deploying it with video. The first question the network engineers asks is "How much bandwidth does it use?"

In this session we'll briefly review the technologies, and then dive into calculating the amount of bandwidth needed for voice and video collaboration with Sametime 9. We'll look at QOS, firewall traversal, B2B/B2C and more.

We'll do this by looking at sample organizations and determine what needs to be understood, documented, configured and maybe upgraded to make these environments ready to roll out Sametime 9 audio and video.

Your Speaker

Peter Lurie has been focusing medium to large organizations on the key things they need to improve communication and collaboration. This includes not just unifying their voice & video environments, but also the plans, policies and procedures to make them effective. With a focus on ease of use, driving adoption, and showing measurable business results Peter has been working with IBM, IBM's partners and IBM's customers for the last 6 years. With 13+ years collaborating around the globe with customers, partners and prospective customers, he’s currently leading a Global UC Architect team at Polycom.

Video glossary from the garden

Video network traffic is like water going through a garden hose: – The throughput or call speed is the amount of water going through the hose in

gallons/minute (or liters/minute).

A measured mile

Note: PINGs use ICMP packets and many routers/switches give these a lower priority,

When using PINGs and measure them at one point you actually measure round trip times. For video, we care about one-way latency and jitter.

VoIP and Video in most cases use UDP packets which routers/switches are likely to give a higher priority.

.... but it's a start.

CLIENTS AND DEVICES

Speaking the language of Video

Bridge (or MCU): The technology that connects multiple people all together on a (video) conference call. Bridges can be audio only or audio & video. Sametimes bridge is called “vMCU”. They can use DSPhardware accelerators or be software only like Sametime’s VMCU.

Point – to – Point call: communication between two people (like a telephone call). Multipoint call: communication

between multiple people (like a conference call). Media flows through a central bridge

SVC vs. AVC calling

Two different standards used by Sametime 9+ clients– SVC and AVC. This choice will affect bandwidth to a specific endpoint (but it’s automatic!) It does not affect bandwidth calcs.

– For Sametime 9.0.x Point to Point almost always uses AVC

– For Multipoint (including all meetings), SVC is used generally used for Sametime 9 clients

• Sametime 8.5.2 does NOT support SVC• Prior versions may not support video at all.

– “SUT Lite” calls to a device will offer SVC first over AVC• Sametime 9 clients and Polycom RMX MCU & endpoints typically have SVC support• Sametime 9 clients can NOT use any other providers SVC implementation (not

compatible) but typically can negotiate AVC.

18

SVC vs. AVC Client Differences

AVC clients sends one video stream of the highest negotiated quality to the MCU. If necessary, a MCU then transcodes (scales up or down, changes format, etc.) the image to whatever the receiving end needs.

SVC clients send multiple streams of the same image. The MCUacts like a video router, forwarding the streams as requested by each client.

Note: Because the vMCU doesn’t transcode, an AVC client connecting to the vMCU will receive the lowest quality!

19

…and in Sametime

The way Sametime implements SVC, there are 3 complete streams of video.

Stream1 + Stream2 + Stream3 <= negotiated call bandwidth

Take at least 3 passes–Population–Site–Job Function/Diversity

Pass 1 – Population but start with requirements

Business requirements:

My company has 2000 people

My boss says they want everyone to be able to do Sametime video at the same time concurrently.

My boss loves his 50” HD TV. He wants everyone to do HD video to their desktop.

26

Now what?

Pass 2 – Site

Have QOS? Use QOS! Don’t have it, get QOS!

The goal of QoS is to provide prioritization of critical network traffic.

If you use VoIP you (hopefully) already have QOS.

What does packet loss look like?

Better late than never does NOT apply to packets!

32

Sametime TURN Server

No TURN server = No video through firewallSametime TURN Server works with Sametime Media Manager, enabling clients to communicate across a NAT or firewall during a multimedia session.

See http://ibm.co/MpdJhz

33

A quick side note: like on a high jitter, high packet loss network…

an undersized vMCU server will have poor video & audio quality. This will look like network problems!

This is especially true in a VM environment. Do not over provision the host or under provision the guest OS in production!!!

Wrap up

Understand the impact on the network. Work with not against the network team.

Can change bandwidth as Sametime Policy by LDAP groups.

Adoption drives utilization (it’s not BAD to have utilization).

Track and update your assumptions.

Do the math. Socialize it with your core network engineers. The more detailed your model, the better your estimates.

When things go wrong, quality is affected FIRST!• QOS, LPR, SAC, etc., all help but if the packets don’t arrive…

Why SVC Only Polycom delivers:

– Seamless integration between AVC and SVC technologies ensure smooth migration based on customer priority

– Investment protection for installed base with 3X capacity for HD multipoint

– Enhanced user experience – includes Scalable Audio Coding (SAC)

– Interoperability with the ~3 million systems in place today

– Readiness for future interoperability

– Enhanced bandwidth efficiency in MP calls with Spatial Simulcast

Spatial Simulcast Benefits vs. Inter-Layer Prediction (ILP)

– More bandwidth efficient for the entire video conference than ILP

– Existing H.264 hardware accelerators (DSPs) can encode and decode simulcast, but not ILP

– Cost / Power savings
