To reduce the energy consumption in the IP and Ethernet transport network, Yamanaka Lab. focuses on automatically construct the least energy consumption network topology by using traffic engineering and dynamically powering off interfaces of routers/switches.

This time, a data center applicable large scale Ethernet testbed is constructed with a market available Ethernet switch (Alaxsala AX6800S) and developed Ethernet switches (now available from Allgreen networks). And then, we successfully demonstrated a self organized network which is automatically construct the least energy consumption network topology by self path reroute and port power on/off control with the MiDORi GMPLS protocol.

Yamanaka Lab. will exhibit the demonstration of this self-organized network at the Keio Techno-Mall2010 at Tokyo International Forum on Dec. 10.
