Alternative Format: Original Text Document
RFC 2171 MAPOS June 1997 1.2 Possible Configurations The MAPOS protocol provides multiple access, broadcast / multicast- capable switched LAN environment using SONET/SDH lines as transmission media. Possible configurations of MAPOS system are shown in the following diagrams. In (a), two end nodes are connected to each other. Figure (b) shows a star-topology "SONET-LAN" where multiple end nodes are connected to an HDLC frame switch. The frame switch forwards packets between nodes and provides multiple access capability. In (c), multiple frame switches are linked together, creating a switching cluster. +------+ +------+ | Node +--------------------------------+ Node | +------+ +------+ (a) Point-to-Point configuration Murakami & Maruyama Informational
