Phase 3: Invoking Network Layer Protocols (Windows Embedded CE 6.0)
1/6/2010
Once the previous phases have been completed, PPP invokes the various Network Control Protocols (NCPs) that were selected during the link establishment phase (Phase 1) to configure protocols used by the remote client. For example, during this phase, the IP Control Protocol (IPCP) can assign a dynamic address to the dial-in user. In the Microsoft implementation of PPP, the compression control protocol is used to negotiate both data compression (using MPPC) and data encryption (using MPPE) for the simple reason that both are implemented in the same routine.
