This document describes a TCP option for use by middleboxes to
facilitate transparent detection of other middleboxes along the path
of the TCP connection during the connection initiation phase. The
option has no effect if an appropriate middlebox is not present on
the path. The TCP end hosts are unaware of this option and its usage
is strictly for use by TCP middleboxes. Multiple vendors of WAN
optimization products have used similar (but incompatible and
proprietary) mechanisms since at least 2004. Those existing vendor
systems use multiple TCP option code points, all of which are
officially unassigned by IANA. The goal of this memo is to
standardize a single TCP option code point for this functionality.
This memo is the product of discussion among some of the vendors
currently using incompatible proprietary TCP options for middlebox
discovery. It is a non-goal of this memo to achieve interoperability
of middlebox discovery between multiple vendors. It needs to be
noted that an earlier document
[I-D.knutsen-tcpm-middlebox-discovery], is re-written as the current
document after agreement from multiple vendors.
