Chapter 3-SVC Conferencing System Architecture
3-2
The SVC-based conferencing system architecture diagram is divided into the following 
sections:
User Plane
The User plane describes the various endpoints that can be deployed in the RealPresence 
UC Platform, which can include room and mobile endpoints, Telepresence systems, voice 
and audio.
In the SVC conferencing solution, only SVC-enabled endpoints such as RealPresence 
Desktop and RealPresence Mobile can use the SVC encoding and decoding capabilities for 
compressed video files. 
Access Plane
The Access plane controls the flow of data from the endpoints to the media servers. The 
Access plane can deploy devices such as ISDN PBX, Polycom RealPresence® Access 
Director™, and so forth. These devices are used to control and manage information security. 
Firewalls can be deployed for additional security.
The Polycom® RealPresence® Access Director™ (RPAD) enables expanded firewall 
traversal options for secured video conferencing connectivity within the enterprise 
environment or with conference participants outside the enterprise firewall.
