Real Time Streaming Protocol server load balancing

Real Time Streaming Protocol (RTSP) is an application-level protocol for controlling delivery of data with real-time properties as documented in RFC 2326. For example, the streams of data in a multimedia presentation--audio, video, and text--must be presented synchronously. A multimedia client like Real Player* or Quick Time Player* downloads these multiple streams of data from multimedia servers and presents them on the player screen. RTSP controls the flow of the multimedia streams. Each presentation uses one RTSP control connection and several other connections to carry the audio/video/text multimedia streams. In this document, the term RTSP server refers to any multimedia server configured for RTSP protocol for multimedia presentation.

The Web Switching Module RTSP implementation supports the following:

Private addressing on the server side.
Layer 7 URL-hashing metric, URL pattern matching, and all Layer 4 metrics for load balancing.
Caching of entire presentations by switching all stream connections and control connections to the same cache server.
RTSP-compliant applications (excluding Windows Media Player because it is not RTSP-compliant).
