A novel reliable routing scheme for Tactile-oriented Internet traffic

Abstract

Over the past few years, many scientists have envisioned an Internet generation that will not only provide voice and data communications but can also support Haptic communications. This new Internet dimension can be beneficial for the society by facilitating the development of new technologies and applications that will improve our standards of living. In this study, we propose a novel traffic engineering policy that can satisfy the extremely strict requirements of the new traffic class associated with Haptic communications. Our proposed policy is based on Multi-Plane Routing (MPR) that consolidates various aspects in all-IP access infrastructures and enables network-wide path diversity. To this end, MPR has been remodeled and extended to facilitate Haptic communications. Our simulation results demonstrate that our proposed policy outperforms intra-domain routing protocols namely Open Shortest Path First (OSPF) and performs near-optimally. It will also become apparent that shortest-path solutions such as OSPF can not be used in order to handle Haptic communications in typical Internet network topologies. Finally, we formulate a binary optimization problem for the selection of the optimal Routing Plane (RP) in terms of the network effects such as delay, jitter and packet loss.
