Abstract:

To solve the problem that the traffic flow dynamically changes in Internet protocol (IP) network, a new energy saving algorithm based on pre-configured multiple topologies (ESPMT) was proposed. In the ESPMT algorithm, firstly, according to the daily traffic flow, each day is divided into multiple time slices, secondly, the energy-saving sub-topology is designed by utilizing neighboring region search for each single time slice. To achieve the purpose of energy saving, the traffic flows are concentrated on some links. The links without traffic are powered off in IP networks.

Key words: Internet protocol network, energy-saving routing, neighboring region search, multiple topologies
