Deployment and adoption of future internet protocols

Many, if not most, well-designed Future Internet protocols fail, and some badly-designed protocols are very successful. This somewhat depressing statement illustrates starkly the critical importance of a protocol's deployability. We present a framework for considering deployment and adoption issues, and apply it to two protocols, Multipath TCP and Congestion Exposure, which we are developing in the Trilogy project. Careful consideration of such issues can increase the chances that a future Internet protocol is widely adopted.
