1. Overview

This document details the changes to GSMP necessary for the support

of optical (non-transparent and all optical), SONET/SDH, and spatial

switching of IP packets, Layer 2 (L2) frames and TDM data. When

implemented, GSMP controllers will then be able to control: photonic

cross-connects (optical-optical), transparent optical cross connects

(optical-electrical-optical, frame independent), opaque cross

connects (optical-electrical-optical, SONET/SDH frames), and

traditional TDM switches (all electrical). The resulting systems

could form IP based optical routers, optical label switches,

wavelength routers, and dynamic optical cross connects.

Several different generic models exist defining how to provide

control plane functionality in an optical network [2], [3], [4].

This document takes no position on which model is most appropriate

(e.g., single or multiple routing plane instances). The only

assumption is that the ability to separate the control mechanisms

from the data switching is as useful for the signaling of optical

paths (e.g., GMPLS) as it is for the signaling of L2 paths (e.g.,

MPLS). Therefore, the requirements contained within are focused only

on the separation of control functions from data functions in order

to provide a more flexible network architecture.

GSMPv3 [5] is well suited for providing the control interface

necessary for allowing an IP based controller to direct the

activities of an optical switch. In order for GSMP to operate

between controllers and optical switches and cross connects, support

for optical labels and service and resource abstractions must be

added to GSMP.

This document also includes changes recommended by implementers that

will facilitate easier development of a GSMP implementation. These

changes consist of rearranging PDU formats, clarification of flags,

transaction identifiers, and response codes.
