Abstract

A principal objective of this document is to describe the underlying framework of middlebox communications (MIDCOM) to enable complex applications through the middleboxes, seamlessly using a trusted third party. This document and a companion document on MIDCOM requirements ([REQMTS]) have been created as a precursor to rechartering the MIDCOM working group.

Abstract

   A principal objective of this document is to describe the underlying

   framework of middlebox communications (MIDCOM) to enable complex

   applications through the middleboxes, seamlessly using a trusted

   third party.  This document and a companion document on MIDCOM

   requirements ([REQMTS]) have been created as a precursor to

   rechartering the MIDCOM working group.

   There are a variety of intermediate devices in the Internet today

   that require application intelligence for their operation.  Datagrams

   pertaining to real-time streaming applications, such as SIP and

   H.323, and peer-to-peer applications, such as Napster and NetMeeting,

   cannot be identified by merely examining packet headers.  Middleboxes

   implementing Firewall and Network Address Translator services

   typically embed application intelligence within the device for their

   operation.  The document specifies an architecture and framework in

   which trusted third parties can be delegated to assist the

   middleboxes to perform their operation, without resorting to

   embedding application intelligence.  Doing this will allow a

   middlebox to continue to provide the services, while keeping the

   middlebox application agnostic.
