Towards single Watt and nJoule/bit routing
MetadataShow full item record
We report on recent progress in our research on how to establish sustainable broadband markets in under-served areas, in this paper focusing on facilitating sustainable power supply by designing low power-consuming routers. We disclose the details of a new generation low power routers, providing wire-speed forwarding between Fast Ethernet connections (100Mbps) over optical fiber at below 5W. Three of these routers have been deployed in the Serengeti Broadband Network in northern Tanzania, which is now an extension of TERNET, the Tanzania NREN. We expect this development to lead to even more energy-efficient routers requiring less than 1W and 1nJ/bit forwarding.
