Multilink and Bandwidth Allocation Protocol

Windows 2000 remote access supports the PPP Multilink Protocol (MP), the Bandwidth Allocation Protocol (BAP), and the Bandwidth Allocation Control Protocol (BACP):

MP allows multiple physical links to appear as a single logical link over which data can be sent and received.
BAP is a PPP control protocol that is used to dynamically add or remove additional links to an MP connection.
BACP is a PPP NCP that elects a favored peer in case both PPP peers request to add or remove a connection at the same time.

Each of these protocols is discussed in greater detail in the following sections.
