Bandwidth Allocation Protocol (BAP) and Bandwidth Allocation Control Protocol (BACP) enhance multilink Point-to-Point Protocol (PPP) by dynamically adding or dropping links on demand. BAP is used for bandwidth management, determining when to add or drop links based on usage. BACP uses Link Control Protocol (LCP) to elect a "favored peer," which has precedence if multiple peers transmit the same BAP request. Both protocols are PPP control protocols and work together to provide bandwidth on demand. In addition, Link Discriminator is a new LCP option used to uniquely identify each link in a multilink bundle.
A Windows 2000 server with BAP enabled can also provide clients with additional phone numbers to dial if extra bandwidth is required. Using this option, clients only need to know one phone number, but can still use extra lines as needed. When a BAP-enabled remote access client requests another connection, the remote access server sends back a message that contains the phone number of an additional modem.
To configure BAP to provide clients with additional phone numbers:
In Routing and Remote Access Manager, click Ports, click Properties, click a port, and then click Configure.
Type the phone number of the modem connected to this port.
