TCP Segment Caching

This internet-draft describes Content- and Cache-Aware TCP (CATCP).
This is an extension to TCP that allows caching of TCP segments, so
they can be re-used between different flows transmitting same data.
When large amounts of redundant data are being simultaneously sent to
multiple receivers, this can lead to significant load reductions and
performance improvements.
A typical use-case might be to improve the efficiency of HTTP-based
streaming video services, through ubiquitous in-network caching.
This draft marks the start of a formal specification of the ideas
previously outlined in our technical report on
Poor Man's Content Centric Networking (with TCP)
