3.3.6 Multiplexing

Two conventions identify what protocols a virtual circuit (VC) is carrying. Be sure to use
the multiplexing method your ISP requires.

3.3.6.1 VC-based Multiplexing

In VC-based multiplexing, by prior mutual agreement, each protocol is assigned to a
specific virtual circuit. For example, VC1 carries IP, etc. VC-based multiplexing may be
dominant in environments where dynamic creation of large numbers of ATM VCs is fast and
economical.

3.3.6.2 LLC-based Multiplexing

In LLC-based multiplexing, one VC carries multiple protocols with protocol-identifying
information contained in each packet header. While this method requires extra bandwidth and
