VC-based multiplexing

In this case, by prior mutual agreement, each protocol is assigned to a specific

virtual circuit; for example, VC1 carries IP. VC-based multiplexing can be

dominant in environments where dynamic creation of large numbers of ATM VCs

is fast and economical.

LLC-based multiplexing

In this case, one VC carries multiple protocols with protocol-identifying

information being contained in each packet header. Despite the extra bandwidth

and processing overhead, this method can be advantageous if it is not practical to

have a separate VC for each carried protocol, for example, if charging heavily

depends on the number of simultaneous VCs.

VPI and VCI

Be sure to use the correct Virtual Path Identifier (VPI) and Virtual Channel

Identifier (VCI) numbers assigned to you. The valid range for the VPI is 0 to 255

and 32 to 65535 for the VCI (0 to 31 is reserved for local management of ATM

traffic).
