This document contains an initial specification for the Explicit Control
Protocol (XCP), an experimental congestion control protocol. XCP is
designed to deliver the highest possible end-to-end throughput over a broad
range of network infrastructure, including links with very large
bandwidth-delay products, which are not well served by the current control
algorithms. XCP is potentially applicable to any transport protocol,
although initial testing has applied it to TCP in particular. XCP routers
are required to perform a small calculation on congestion state carried in
each data packet. XCP routers also periodically recalculate the local
parameters required to provide fairness. On the other hand, there is no
per-flow congestion state in XCP routers.
