destination service access point (DSAP)

A Destination Service Access Point (DSAP) is an individual address of the addressed service access point or a summarized group address of a MAC address in the upper protocol layers of the network protocols.

The Destination Service Access Point is an 8-bitdata field that Logical Link Control( LLC) can use to trace multiple connections across 802 networks.

The DSAP frame consists of a total of 8 bits. The first six bits are address bits, followed by a bit that indicates that the address bits are user-defined. These 7 bits form the address of the Destination Service Access Point (DSAP). The eighth bit is marked as the I/G bit and indicates whether the destination address is an individual address or a group address.
