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 fixed, wired, connected, relatively reliable, and low-to- moderate delay Internet. ResTP is developed to efficiently carry trafic from various application types across a wide variety 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 specific mission requirement, application type, and underlying network characteristics. In addition, ResTP can exploit multiple available paths for its data transmission to increase redundancy while better utilizing network resources. With the design based on our ResiliNets frame- work, we believe that ResTP is the first transport-layer protocol that considers all disciplines related to resilience.
