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.
This document is a product of the Middlebox Communication Working
Group of the IETF.
