McGraw-Hill©The McGraw-Hill Companies, Inc., 2004 Figure MAC frame Additional addressing (DSAP/SSAP or destination/source Service Access Point; software addresses) is provided by the LLC to supplement the addressing provided by the MAC. A workstation in the LAN has a single MAC (physical) address. A any given time, a workstation might simultaneously handle several data exchanges originating from different upper-layer protocols (e.g., IP, Novell IPX, SNA) but operating over this same physical connection. The SAPs specify in which memory buffer the NIC places the frame contents, thus allowing the appropriate higher- layer protocol to retrieve the data. For more information refer to “Communication Networks” by Garcia and Widjaja. Packet (PDU) from the network layer.
