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 mechanism for supporting Version 4 of the
   Internet Protocol (IPv4) on Version 1 of the Multiple Access Protocol
   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 a protocol for transmission of the Internet
   Protocol Version 4 (IPv4) over Multiple Access Over SONET/SDH (MAPOS)
   version 1. MAPOS is a link layer protocol and provides multiple
   access capability over SONET/SDH links. IP runs on top of MAPOS. This
   document explains IP datagram encapsulation in HDLC frame of MAPOS,
   and the Address Resolution Protocol (ARP).

1. Introduction

   Multiple Access Protocol over SONET/SDH (MAPOS) [1] is a high-speed
   link-layer protocol that provides multiple access capability over
   SONET/SDH. Its frame format is based on the HDLC-like framing [2] 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) [3] datagrams are
   transmitted in MAPOS HDLC frames [1].

   This document describes a protocol for transmission of IP datagrams
   over MAPOS version 1 [1]. It explains IP datagram encapsulation in
   HDLC frame of MAPOS, and ARP (Address Resolution Protocol) for
   mapping between IP address and HDLC address.
