XCP-i (Interoperable eXplicit Control Protocol)
XCP (eXplicit Control Protocol) is a transport protocol that uses the assistance of specialized routers to very accurately determine the available bandwidth along the path from the source to the destination. We propose XCP-i  which is operable on an internetwork consisting of XCP routers and traditional IP routers without loosing the benefit of the XCP control laws
An ns-2 module simulating XCP-i has been developed and will be available on the web. Based on a Linux kernel, a software XCP-i router is currently under development.
