On the Design and Analysis of a Resilient Transport Protocol

Abstract

We present the design and simulation analysis of ResTP, a multipath-capable configurable and adaptive transport-layer protocol developed for Future Internet resilience and survivability. ResTP is distinct from the conventional transport protocols such as TCP, UDP, and MPTCP by the flexibility in its design so that it can satisfy the requirements of various traffic classes, application types, and taking into account the underlying network characteristics, and its emphasis on achieving resilience, an essential property that is unfortunately lacking in the current Internet system. In this paper, we perform a simulation evaluation of ResTP, with the focus on its single-path mode, in comparison with TCP and UDP under various network conditions to show that ResTP can be used in place of these standard protocols with no performance loss. In some scenarios, ResTP outperforms the standards due to its flexibility in adopting the appropriate set of algorithms for specific application needs and network conditions.
