Abstract:
Much of the growth in bandwidth demand and power consumption in today’s Internet is driven by the transport of large media files. This work presents a power-efficient overlay network specifically designed using electronic burst switching for these large files. The two approaches are presented in which electronic bursts or media frames (MF) containing >1Mb are routed in a manner similar to UDP or concatenated into periodic semi-transparent chains and routed using a two-way reservation protocol. Utilization, blocking, delay and buffer size are compared to UDP/IP by means of simulation. Both approaches dramatically reduce header-related power consumption. Concatenation also reduces significantly the amount of buffer space required. A representative router design is evaluated showing a potential energy saving of roughly 80% relative to standard IP routers.
