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].
