Address Families

  • Article

An address family (AF) represents an association between one of the following sets of drivers:

  • A connection-oriented client, a call manager, and the underlying connection-oriented miniport driver.

  • A connection-oriented client and an MCM driver for a specific signaling protocol.

An address family also specifies a particular signaling protocol.

A call manager or MCM driver advertises its call manager services for a specific signaling protocol by registering the address family with NDIS. NDIS then notifies each client on the binding of the newly registered address family. Before it can use the call manager services provided by a call manager or MCM driver, a connection-oriented client must open the address family with the call manager or MCM driver that advertised it.
