Introduction + + Multiple Access Protocol over SONET/SDH (MAPOS) [1] is a high-speed + link-layer protocol that provides multiple access capability over + SONET(Synchronous Optical Network)/SDH(Synchronous Digital + Hierarchy)[2][3][4][5]. Its frame format is based on the HDLC-like + framing [6] for PPP. A component called "Frame Switch" [1] allows + multiple nodes to be connected together in a star topology to form a + LAN. Using long haul SONET/SDH links, the nodes on such a "SONET-LAN" + can span over a wide geographical area. The Internet Protocol (IP) + [7] datagrams are transmitted in MAPOS HDLC frames [8]. + + This document describes the protocol parameters used in MAPOS version + 1 [1]. + + + + + + + +Maruyama & Murakami Informational [Page 1] + +RFC 2172 MAPOS June 1997 + + +2. Protocol Field Assignments + + The MAPOS Version 1 Data Link Layer [1] contains a 16 bit Protocol + field to identify the the encapsulated protocol. The Protocol field + is consistent with the ISO 3309 (HDLC) extension mechanism for + address fields. All protocol numbers MUST be assigned such that the + least significant bit of the most significant octet equals "0", and + the least significant bit of the least significant octet equals "1". + + Assigned MAPOS Protocol Numbers + + Value (in hex) Protocol Name + + 0001-001F Not Used - reserved + 0021 MAPOS Version 1 Internet Protocol Version 4 [8] + 0023-FCFF Not Used - reserved + FE01 MAPOS Version 1 Address Resolution Protocol (ARP[8]) + FE03 MAPOS Version 1 Node Switch Protocol (NSP[9]) + FE05 MAPOS Version 1 Switch Switch Protocol (SSP[10]) + FE07-FEFF Not Used - reserved + + +References + + [1] Murakami, K. and M.
