3. 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.

6. 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.

9. Level Setting – a Glossary of Video-Specific Terms
A quick review of what it all means
 Is applicable to IBM Sametime 9 (and 8.5.2 IFR 1)
 Is applicable to Standards Based Video from Polycom, Cisco and others.
 Is (even) applicable to Microsoft Lync 2013.

10. 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).

11. 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).
– Latency is the amount of time it takes water to go through a section of hose

12. 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).
– Latency is the amount of time it takes water to go through a section of hose
– Jitter is how much that time varies if someone steps on the hose.

– Latency is the amount of time it takes water to go through a section of hose.

– Packet Loss is each drop of water that leaks out of the hose.

– Latency is the amount of time it takes water to go through a section of hose.
– Jitter is how much that time varies if someone steps on the hose.
– Packet Loss is each drop of water that leaks out of the hose.
– Quality of Service (QoS) is a high priority pathway through the garden to get to the
destination

15. 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.

16. CLIENTS AND DEVICES

17. Speaking the language of Video
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
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 DSP
hardware accelerators or be software only like Sametime’s VMCU.

18. 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

19. 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 MCU
acts 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

20. …and in Sametime
The way Sametime
implements SVC, there
are 3 complete streams
of video.
SVC
Stream1 + Stream2 +
Stream3 <= negotiated

24. EFFECT ON THE NETWORK

25. Ready to do the Math?
 Capacity planning is an art, not a
science. DOCUMENT YOUR
ASSUMPTIONS
 Understand your network
 Leverage any phone/pbx
information…
 Take at least 3 passes
– Population
– Site
– Job Function/Diversity
 Monitor and adapt
25 25

26. 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.

30. 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.
30

31. 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 firewall
Sametime 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
32

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!!!
33

34. 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… 

46. 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
