Abstract:
Content-Centric Networking (CCN) is a new network architecture aiming to solve many fundamental problems of IP networks. We are interested in the application of CCN carrier networks during natural disasters. During these times, carrier networks need to save energy until reinforcement arrives. Traffic delivery is prioritized, where high-priority traffic such as disaster news receives superior transmission quality. Multiple Tree-based Traffic Engineering (MTTE), a recently proposed traffic engineering scheme, realized the goal of energy-saving by forwarding traffic on minimal spanning trees. In addition, several priority-aware transmission schemes were proposed recently. However, no CCN communication scheme that realizes both energy-saving and prioritized routing has ever been considered. In this paper, we propose Priority-aware MTTE (PMTTE) to fill this vacuum. Given a certain energy consumption limitation, PMTTE optimizes the transmission quality of the high-priority traffic first. Then, it uses the remaining energy consumption quota to improve the low-priority traffic’s quality. We compared the performance of PMTTE against priority queue-enabled MTTE (as a naive energy- and priority-aware CCN traffic engineering scheme). Simulation shows that compared with MTTE, PMTTE can improve the performance of high-priority traffic by up to 80%, and of low-priority traffic by more than 30%.
