The Motivation for Multiplexing
Tunneling Multiplexed Compressed RTP
Other Approaches to Multiplexing
Multiplexing and tunneling provide an alternative to header compression, improving the efficiency of RTP by bundling multiple streams together inside a single transport connection. The aim is to amortize the size of the headers across multiple streams, reducing the per-stream overhead. This chapter discusses the motivation for multiplexing and outlines the mechanisms that can be used to multiplex RTP streams.
Header compression reduces the size of the headers of a single RTP stream, on a hop-by-hop basis. It provides very efficient transport but requires cooperation from the network ...
