The PARs will now be submitted to the IEEE-SA Standards Board. Where the board's New Standards Committee (NesCom) will review them and make a recommendation to the Standards Board about whether to approve them. thus initiating development of the standards. According to the Ethernet Alliance, the HSSG investigated the needs and requirements for the next speed of ethernet technology and found a divergence in bandwidth demand between the networking and computing industries. "It was discovered 100GbE would likely best meet the demands of the next generation Internet backbone and network aggregation points. In enterprise computing, 40GbE better matches the bandwidth demand driven by server technologies such as host bus interfaces, memory speeds, and multi-core processing." "The Ethernet Alliance members contributed to the HSSG efforts and provided pivotal input as the study group developed its recommendations for a single [project approval request] with two rates to accommodate the growing bandwidth demands in both the networking and computing industries," said Brad Booth, president, of the Ethernet Alliance. "The Ethernet Alliance members look forward to supporting the progress towards the development of 40GbE, 100GbE and energy-efficient ethernet standards." The HSSG has established a set of objectives including copper and optical physical layer (PHY) interfaces tailored for the intended applications. The 40GbE rate includes PHY solutions to cover distances up to 100 metres, and the 100GbE rate includes PHY solutions to cover distances up to 40kms The EEESG investigated the technical feasibility and market potential for a protocol to change the link speed on-the-fly to realise power savings in under-used links and has established a set of objectives to include unshielded twisted-pair (UTP) copper cabling links and backplane ethernet links. {moscomment}
