Power-Aware Traffic Engineering with Named Data Networking

Power-aware traffic engineering puts some links to sleep by moving their traffic to other links. However, this can make the utilization of remaining links higher, especially when the traffic amount is large. There is a tradeoff between the number of sleeping links and the utilization of links. To solve this problem, we propose to use a state-of-the-art networking called Named Data Networking (NDN), which can cache and retrieve the content in the storable routers. This can facilitate power-aware traffic engineering, because some traffic does not need to travel through the core network any more, and it only ends up at the edge routers which have already cached the required content. We use NDN to balance the traffic demand between origin-destination core routers so that traffic demand through the network can be adjusted to satisfy the requirement of power-aware traffic engineering. We evaluate power-aware traffic engineering with NDN and show its advantage compared to the one with conventional networking.
