RTCP is a tool that fault-tolerant applications can use to recover their TCP connections after crashing or migrating; it masks the application failure and enables transparent recovery, so the remote peers remain unaware.
The “R” can stand for Recoverable, Replicated, Reliable, or even Robert's.
RTCP is part of a collaboration with Robert Broberg and others of Cisco Systems, as an element of ongoing effort to create a highly-available, reliable Internet backbone router.
Distributions and the development git repository are available through SourceForge.
