Multipoint Video Conferencing
Multiple solutions to enable multipoint conferencing.
Participants send their audio/video stream to centralized device (MCU/CTMS)
Device selects, possibly re-encodes, and retransmits audio/video to participants
Cascading a possibility for some
MCUs (better BW optimization but some loss of functionality)
Device Usage
Cisco TelePresence Multipoint Switch (CTMS) Immersive Cisco TelePresence multi-party
TelePresence Server Active-Presence & Transcoded TelePresence
TelePresence MCU Multipoint Transcoded Video Conferencing
Multi-site on certain endpoints Adhoc multipoint conferencing

Cisco TelePresence Multi-Point Meetings Multipoint latency considerations
For small deployments centrally locate multipoint resources
Target a one way end-to-end network latency of < 150ms
Calculate worst case latency by adding the longest two legs
-+ latency of multipoint bridge/switch
Sites with relatively low latency point-to-point may have much higher latency with multipoint
For Large deployments regionalize multipoint resources and manage meeting with CTS-Manager

Traditional Video Conferencing MCU
Endpoints send audio and video towards central MCU
MCU
- Receives, blends/selects media and transmits
Mixes audio
Transcodes video to match receiving endpoint capabilities
- Performs interop between devices
- May operate in screen switching or composite modes
MCUs are placed at:
- High WAN bandwidth connected sites
- Balancing end to end latency

WAN
Endpoint Integrated Video Bridges
Specific VCS based models (MultiSite on EX, MXP, etc.) may offer option of MCU like functionality for ad-hoc conferencing.
- Low cost multiparty option that provides limited number of participants
Lead unit receives and retransmits media streams
Can create dynamic stress points within network, lead unit is poorly chosen.
Features can generally be disabled to force use of well connected MCUs

Traffic Details IP Telephony and Video Conferencing
IP Telephony and video conferencing almost always use RTP
- RTP (RFC3550) over UDP
RTP header provides
- Sequencing Timestamp Payload types Multiplexing of different media
RTCP (RTP UDP port + 1) provides
- Reporting Control channel

Media (RTP)

RTP and Media types
Each media stream (audio, video, desktop share, etc.) is a unique SSRC
Implementation specific: multiple SSRCs of same media type might be multiplexed together (same IPsrc, IPdst, UDP protocols)
CTS:
- 1 Audio UDP flow (multiple audio channels) 1 Video UDP Flow (multiple channels)

RTP Payload Types
RTP Payload Type (PT) field designates type of media
Divided into static (mostly legacy audio) and dynamic.
- http://www.iana.org/assignments/rtp-parameters
Dynamic range (96-127) PT communicated via signaling (SIP, H.323)
- Identifying video can become a challenge.

Why Monitor Video Services?
Video service delivery validation & troubleshooting
End users associate poor video quality with poor network service
Validation via monitoring will lead to earlier identification of issues and greater confidence in network
Video is sensitive: early detection of network issues that may affect all traffic
Contractual SLAs need to be validated
Violations may incur punitive costs

Detection & Troubleshooting
Methodology for troubleshooting: The 4 A’s
This session will focus on tools and methodologies for
- Assess and Acquire
Assess
• Your Senses
• User Reports
• Automated Alerts
Acquire
• What is the issue?
• What is NOT the issue?
• Identify place in call lifecycle
Analyze
• Narrow possible causes
• Most likely cause?
Act
• Test Theory
• Confirm Root Cause
• How to prevent?
• How to detect better?
© 2011 Cisco and/or its affiliates. All rights reserved. Cisco Public BRKEVT-2804 23
Call Life Cycle
Identify where in the Call Life Cycle did the call Fail
- Did the calling party receive ring back?
- Did the called party phone ring?
- Did the call fail before or after it was picked up?
- Did two way audio or video establish and then drop?
- Did the users experience one-way audio/video?
- Did audio/video drop after a few seconds?

Assess & Acquire Proactive Steps
Be prepared and have data collection systems enabled
- Enable passive monitoring
Call signaling and endpoint logging systems: CDR, Syslog, SNMP Traps etc.
Session monitoring on endpoints, application infrastructure and network
- Enable active tests
Periodic endpoint to endpoint calls
Network performance probes
Helpdesk
- Interview Script
- Access to tools, logs, etc.

The Simple Stuff: Endpoint Registration
Video endpoints register to signaling system
- Allows signaling system to ‘find’ endpoint in the event of an incoming call
- Allows endpoint entry into signaling system for outgoing calls
- Allows discovery of endpoint by some management systems (eg. CPCM)
Endpoints may register to management system (eg. TMS)
- Endpoint health, configuration, software image

Cisco IOS NetFlow—What Is It?
Developed and patented at Cisco Systems in 1996
NetFlow is the de facto standard for acquiring IP operational data
Standardized in IETF via IPFIX
Provides network and security monitoring, network planning, traffic analysis, and IP accounting
Packet capture is like a wire tap
NetFlow is like a phone bill

Dynamic Monitoring with Mediatrace
Mediatrace discovers and queries L2 and L3 nodes along a flow’s path
Gathers system resource, interface and flow specific (perf-mon) stats
- For performance monitor: dynamically configures monitoring policy (if needed) 5-tuple + intervals etc. match static policy).
Consolidates information into a single screen
Allows for easy comparisons of device behavior
- Which interface dropping packets?
- Where is DSCP getting reset?
Can be requested by remote device
Automatically (based on thresholds) via EEM script
Let mediatrace do the walking for you!

Quick Mediatrace
Available via:
- Cisco IOS Exec CLI
- Periodic configuration via IOS configuration
- Launch from endpoints
Modes:
- Hop Poll: performs only path discovery
- System Poll: in addition to performing node and interface discovery, statistics from the interfaces are collected
- Perf-Mon Poll: collects flow specific statistics. If additional
- information, such as the IP protocol and Layer 4 ports, is specified, the query will be as detailed as possible

Intercompany and external calls Models
Three conceptual models for business-to business (B2B) collaboration:
Extranet
Two or more enterprises interested in B2B communication establish direct
network connectivity through an IP or MPLS VPN.
Cisco deployments rely on the Cisco Unified Border Element (CUBE) or Session
Border Controller (SBC) to provide security and firewall/network address
translation (NAT) traversal.
Exchange
Alternative business-to-business architecture where session and access control is centralized in the form of video service exchanges.
Over the Internet
VCS Expressway used as gateway towards the Internet.
WebEx based desktop, voice and video collaboration.
