Abstract
A simplified data link protocol which may be implemented in a very high-speed transmission system, e.g., SONET, processes a datagram received from an IP facility according to QoS considerations and scrambles a datagram before it is again scrambled by a transmission system, e.g., a SONET transmitter, to ensure that the pattern of a user's data does not match the transmission scrambling pattern. The data link protocol scrambler also employs a novel synchronization scheme. We also use a pointer system which identifies the location of a datagram in a frame to eliminate flags and the need to process user data to ensure that it does not contain and a boundary flag.
