       MAPOS - Multiple Access Protocol over SONET/SDH  Version 1

Status of this Memo

   This memo provides information for the Internet community.  This memo
   does not specify an Internet standard of any kind.  Distribution of
   this memo is unlimited.

Authors' Note

   This memo documents a multiple access protocol for transmission of
   network-protocol datagrams, encapsulated in High-Level Data Link
   Control (HDLC) frames, over SONET/SDH.  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 MAPOS, Multiple Access Protocol
   over SONET/SDH, for transmitting network-protocol datagrams over
   SONET/SDH.  It focuses on the core protocol -- other documents listed
   in the bibliography may be referenced in conjunction with this
   document to provide support and services for protocols at higher
   layers.

1. Introduction

1.1 SONET/SDH

   The Synchronous Optical Network/Synchronous Digital Hierarchy
   (SONET/SDH) [1][2][3][4] family of ITU-T standard protocols are
   designed to provide common, simple, and flexible interface for
   broadband optical fiber transmission systems.  It enables direct
   octet-synchronous multiplexing of lower rate tributaries.
   SONET/SDH-compliant transmission systems are widely deployed by
   telephone carriers world wide.

   This document defines the MAPOS protocol -- a method for transmitting
   HDLC frames over SONET/SDH. The protocol provides multiple access
   capability to SONET/SDH, an inherently point-to-point link. This
   enables construction of seamless networking environment using
   SONET/SDH as transmission media for both LAN and WAN.
