Authors' Note
This memo documents a MAPOS (Multiple Access Protocol over SONET/SDH)
version 1 extension, Switch Switch Protocol which provides dynamic
routing for unicast, broadcast, and multicast. 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 MAPOS version 1 extension, SSP (Switch
Switch Protocol). MAPOS is a multiple access protocol for
transmission of network-protocol packets, encapsulated in High-Level
Data Link Control (HDLC) frames, over SONET/SDH. In MAPOS network, a
SONET switch provides the multiple access capability to end nodes.
SSP is a protocol of Distance Vector family and provides unicast and
broadcast/multicast routing for multiple SONET switch environment.
1. Introduction
This document describes an extension to MAPOS version 1, Switch
Switch Protocol, for routing both unicast and broadcast/multicast
frames. MAPOS[1], Multiple Access Protocol over SONET (Synchronous
Optical Network) / SDH (Synchronous Digital Hierarchy) [2][3][4][5],
is a link layer protocol for transmission of HDLC frames over
SONET/SDH. A SONET switch provides the multiple access capability to
each node. SSP is a dynamic routing protocol designed for an
environment where a MAPOS network segment spans over multiple
switches. It is a protocol of Distance Vector family. It provides
both unicast and broadcast/multicast routing. First, this document
describes the outline of SSP. Next, it explains unicast and
broadcast/multicast routing algorithms. Then, it describes the SSP
protocol in detail.
