Authors' Note

   This memo documents the parameters used in the Multiple Access
   Protocol over SONET/SDH Version 1.  This document is NOT the product
   of an IETF working group nor is it a standards track document.  It
   has not necessarily benefited from the widespread and in-depth
   community review that standards track documents receive.

Abstract

   This document describes the protocol parameters used in the Multiple
   Access Over SONET/SDH (MAPOS) version 1. MAPOS is a link layer
   protocol and provides multiple access capability over SONET/SDH
   links.

1. 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].
