Abstract:
Content-Centric Networking (CCN) is a new network architecture aiming to solve many fundamental problems of existing IP networks. CCN is unique in that it widely deploys caches on routers to reduce redundant data transmission. Introducing caches into routers, however, causes the networks to consume extra energy. Although great research effort has been put for improving energy efficiency in IP networks, little work has been done for CCN networks yet. We designed an online traffic engineering algorithm called Multiple Tree-based Traffic Engineering (MTTE) to fill this void. Our approach is to make traffic flow on a small portion of edges in the network and shut down underutilized edges. Data are delivered on multiple tree-topology networks that are dynamically created based on the physical network topology and the current network traffic pattern. The trees are carefully constructed so that they contain minimal edges and mitigate congestion. Simulations using network topologies of real-world autonomous systems show that by using MTTE, up to 45% of the edges can be shut down. To the best of our knowledge, MTTE is the first online green mechanism for CCN.
