The document discusses Lync to the future with Skype integration, Lync 2013 mobility experience and architecture, Lync 2013 and WiFi, and Lync 2013 video. Key points include: - Lync will integrate with Skype to combine Skype's consumer reach with Lync's enterprise controls and features through federated presence, audio calling, and instant messaging. - Lync 2013 mobile clients are available for Windows Phone, Android, iPhone and iPad and provide presence, instant messaging, audio/video calls, and meeting capabilities. The mobile architecture uses static registration to improve mobile presence handling. - WiFi is important to enable BYOD and mobility within enterprises while reducing cellular usage. However, WiFi

44. Real Time Media Network Traffic
• Consistent flow of data packets
• Sensitive to delay, jitter and packet loss
• Random loss can be compensated – sequential
loss is problematic
• Interruptions have notable effect on experience
(voice)
• High bitrate is coming with HD video (1.5+ Mbps
each way per stream)

45. Real-Time Media Characteristics
Streaming vs. Real-Time Media
• Video playback applications like YouTube, Netflix, etc can utilize large receive side
buffers in order smooth out network delays
• Real-Time media is interactive and requires a high performance network that can
sustain continuous up/down stream traffic, with low-latency, low jitter
Impact to Human Interaction
• Human communication starts to get negatively impacted with latency of more than
250 msec
• Bursty jitter or packet loss over a certain threshold cannot be recovered, and leads to
glitches in the audio and video stream
• Especially audio (voice) glitches are very disruptive and lead to a poor user
experience

46. Wi-Fi Issues - Off-Channel Scanning
Background scanning
mechanisms can be too long
and inconsistent which affects
UC real-time media traffic

47. Wi-Fi Issues - Real-World
Handover Performance
• UC real-time media sessions have very
different requirements when roaming
between APs then traditional data
sessions
• Delayed handovers from sticky stations
can result in multi-second media breaks
for UC voice/video
• Stations often ‘stick’ to an associated
AP even when its signal strength has
deteriorated so far as to be unusable.
This is because many stations are not
optimized for proper roaming in a multi-
AP environment

48. Wi-Fi Issues - Rate Adaption and TX
Retries
• Existing station rate adaption
algorithms not well suited for
UC
• May take up too much airtime
in retries for UC real-time
media traffic

49. iPad 3 Characteristics (Over WiFi)
Max Video Resolution
• Send: up to QVGA (424x320) @15fps
• Receive: up to VGA (640x480) or 360p (640x360) @15 fps

• IM + Appsharing (Conf) : up to 9 hours
• IM + Appsharing + Video (conf) : up to 6 hours and 30 minutes
Data Usage
• IM + Appsharing : 766 MB in 9 hours = 189 kilobit/sec average
• IM + Appsharing + Video : 2386 MB in 6 hours 40 minutes = 795 kilobit / sec
average

50. iPhone 4 Characteristics

Dynamic layouts, by giving endpoints the ability to control their received video
HD 1080p 30fps video without the need for high-end processing, taking advantage of CPUs with
Accelerated Processing Units
(Intel Sandybridge, Ivybridge and AMD Fusion)
Standards-based
Based upon Unified Communications Interoperability Forum (UCIF) specification for video, transport

Bit stream compatible with other video conferencing vendors (H.264 AVC)
Reduced need for “heavy lifting” where interoperability is required
