This draft discusses the applicability of the Megaco/H.248 device control protocol [1] as the Middlebox communication protocol. It discusses the architectural similarities between Megaco and Midcom and how Megaco meets most of the key requirements for the Midcom protocol. Modeling the underlying Middlebox resources (such as, filters, policy rules etc) as separate elements from the Megaco entities allows the usage of the protocol as-is, satisfying some of the resource access control requirements. Minimal extensions in the form of new Termination/Package definition (without impacting the base protocol) are sought for Midcom. The Midcom protocol profile and other extensions/packages will be specified in a separate internet draft.
