bandwidth allocation control protocol (BACP)

The Bandwidth Allocation Control Protocol (BACP) is a protocol for automatic bandwidth scaling of connections. The BACP protocol is a companion protocol for Bandwidth Allocation Protocol( BAP) control.

The BACP protocol is enabled by the Point to Point Protocol( PPP) and can allocate or remove additional channels to applications during an existing connection using the BAP protocol. The BAP protocol, working in conjunction with the BACP protocol, takes care of scaling the bandwidth requirements on the connection.

In the case of ISDN, the BACP protocol can interconnect up to 30 channels and manage up to 480 channels. The BACP protocol was specified by the Internet Engineering Task Force( IETF) and is described in RFC 2125.
