Middlebox Communications Protocol Semantics
RFC 3989, “Middlebox Communications Protocol Semantics”, is an Informational document published in February 2005 by M. Stiemerling, J. Quittek, T. Taylor. It has been obsoleted by RFC 5189 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.
Abstract
This memo specifies semantics for a Middlebox Communication (MIDCOM) protocol to be used by MIDCOM agents for interacting with middleboxes such as firewalls and Network Address Translators (NATs). The semantics discussion does not include any specification of a concrete syntax or a transport protocol. However, a concrete protocol is expected to implement the specified semantics or, more likely, a superset of it. The MIDCOM protocol semantics is derived from the MIDCOM requirements, from the MIDCOM framework, and from working group decisions. This memo provides information for the Internet community.
