Ethernet Alliance(R) Supports Progress towards Higher Speed Ethernet and Energy-Efficient Ethernet Standards.IEEE (Institute of Electrical and Electronics Engineers, New York, www.ieee.org) A membership organization that includes engineers, scientists and students in electronics and allied fields. 802.3 Working Group Approves Project Authorization Requests for 40 Gigabit Ethernet An Ethernet standard that transmits at 1 Gbps. Used mostly to connect high-end workstations and servers as well as for network backbones, Gigabit Ethernet transmits full duplex from point to point using switches and half duplex in a shared environment (CSMA/CD) using a hub. , 100 Gigabit Ethernet and Energy-Efficient Ethernet MOUNTAIN VIEW, Calif. -- The Ethernet Alliance The Ethernet Alliance includes component suppliers, industry experts, university and government professionals who formed a consortium to promote industry awareness, acceptance and advancement of Ethernet technology and products based on existing and emerging IEEE 802 Ethernet announces the recent decisions by the IEEE 802.3 working group to forward project authorization requests (PARs) for the next generation of Ethernet technologies. The Higher Speed Study Group (HSSG HSSG High Speed Study Group HSSG High-Speed Signal Generator (Tektronix) ) was formed in July 2006, and its proposal envisions a single project encompassing a 40 Gigabit Ethernet (40GbE) rate for server and storage applications and a 100 Gigabit Ethernet (100GbE) rate for network aggregation. The Energy-Efficient Ethernet Study Group (EEESG) was formed in November 2006, and its proposal envisions a protocol to permit power savings in Ethernet networking equipment. "The Ethernet Alliance members contributed to the HSSG efforts and provided pivotal input as the study group developed its recommendations for a single PAR with two rates to accommodate the growing bandwidth demands in both the networking and computing industries," said Brad Booth, president, 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 investigated the needs and requirements for the next speed of Ethernet technology. A key finding was 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 See Internet2. 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 HSSG has established a set of objectives including copper and optical physical layer (PHY See physical layer and physical. ) interfaces tailored for the intended applications. The 40GbE rate includes PHY solutions to cover distances up to 100 meters, and the 100GbE rate includes PHY solutions to cover distances up to 40 kilometers. The EEESG investigated the technical feasibility and market potential for a protocol to change the link speed on-the-fly to realize power savings in under-utilized links. The EEESG has established a set of objectives to include unshielded Adj. 1. unshielded - (used especially of machinery) not protected by a shield unprotected - lacking protection or defense twisted-pair (UTP UTP (uridine triphosphate): see uracil. (Unshielded Twisted Pair) See twisted pair. UTP - unshielded twisted pair ) copper cabling links and backplane Ethernet links.
