Five Ethernet standards planned by year-end Ethernet is on the verge of one of its biggest makeovers in some time. Before the end of the year, five different IEEE 802.3 task forces are scheduled to finish their work on Ethernet-related standards. Beating WLANs into submission, Part 1: Airtime management The IEEE ratified the bare bones Wi-Fi standard in 1997. Since then, equipment vendors and various 802.11 working groups have been beating it into submission with formal extensions and proprietary capabilities to render it a business-grade network. Much of the ongoing work relates to controlling the shared airwaves in ways that prevent big transmissions from any one client from squeezing out other clients' traffic. Declines expected for Ethernet switches, service provider routers The struggling economy is going to make 2009 a tough year for most network equipment. The Ethernet switch market is about to undergo its sharpest decline since the dot-com bust, and the market for service provider routers is expected to see its first decline in seven years, according to recent reports from the Dell'Oro Group. Nortel to shed shareholders meeting, more employees Nortel recently revealed plans to cancel its annual shareholders meeting, requested an extension to its bankruptcy protection, and indicated that more layoffs are on the way, in addition to other cost-cutting measures. Voltaire unleashes 40Gbps data center switch Voltaire this week announced a 40Gbps InfiniBand switch switch for data centers that's designed to provide a low latency fabric for large, high-performance clusters. Alcatel-Lucent broadens Carrier Ethernet lineup Alcatel-Lucent unveiled enhancements to its Carrier Ethernet lineup that include a customer premises switch for business VPNs. IEEE task forces move forward on Ethernet standards IEEE task forces made progress on Power over Ethernet Plus, 10G Ethernet Passive Optical Networks, Energy-Efficient Ethernet and Higher-Speed Ethernet at the 802.3 interim meetings last week. IEEE advances PoE Plus spec An IEEE task force has reached a milestone in its quest to increase the power that can be delivered to devices using the Power over Ethernet standard.
