Chapter 12. Multiplexing and Tunneling

• 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.
