1 Introduction

This specification specifies MSDTC Connection Manager: OleTx Multiplexing Protocol (CMP) that multiplexes multiple shortlived connections over a long-lived full-duplex session. CMP provides connection management, and message packaging into a box car mechanism for upper layer transaction-based protocols. It uses MSDTC Connection Manager: OleTx Transports Protocol [MS-CMPO] for the long-lived sessions that it uses for transport. CMP enables multiplexing multiple logical protocol connections through a single CMPO connection, which reduces the number of messages that are exchanged over the wire. CMP supports both multiplexing multiple logical sessions over a single CMPO session and multiplexing multiple protocol messages into a single CMPO.

Sections 1.5, 1.8, 1.9, 2, and 3 of this specification are normative. All other sections and examples in this specification are informative.
