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.
