Chapter 3-SVC Conferencing System Architecture
3-2
The SVC-based conferencing system architecture diagram is divided into the following
sections:
•"User Plane”
•"Access Plane”
•"Media Plane”
•"Call Control Plane”
•"Management and Provisioning Plane”
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.
