ResTP - A Transport Protocol for FI Resilience

Abstract

To support emerging application classes and network use paradigms for Future Internet resilience, we are designing a new transport protocol: ResTP. ResTP overcomes the lim- itations of TCP and UDP that evolved in the context of the xed, wired, connected, relatively reliable, and low-to- moderate delay Internet. ResTP is developed to e ciently carry tra c from various application types across a wide va- riety of network types. By supporting cross-layering, ResTP allows service tuning by the upper application layer while promptly reacting to network condition changes by using the feedback from the lower network layer. ResTP supports a set of transport-layer services, and each service is comprised of many mechanisms and algorithms that can be combined based on the speci c mission requirement, application type, and underlying network characteristics. In addition, ResTP can exploit multiple available paths for its data transmis- sion to increase redundancy while better utilizing network resources. With the design based on our ResiliNets frame- work, we believe that ResTP is the rst transport-layer pro- tocol that considers all disciplines related to resilience.
