How non-green is your network? Energy saving has so far focused on PCs, servers and the like, but now networks have been fingered as major wasters of power. An industry group has claimed that Ethernet's poor use of energy could be wasting as much as $450m a year - or 5.8TW/h - in the US. And perhaps three times that much, worldwide.â¦

(InfoWorld) - On Wednesday, Cisco Systems announced an upgrade of its Catalyst switching portfolio to include 10-gigabit Ethernet uplink and extensive PoE capabilities. The full Class 3 15.4 watt power delivery capability through each port on the device is "an industry first," Cisco said. PoE is a way of powering certain network devices, such as IPÂ phones, through the switch connection rather than plugging them into a nearby main outlet. The PoE capability is backed by Ciscoâs Redundant Power Systems as a recommended network product option. The 10Gb Ethernet capability can be accessed by replacing the Twin Gigabit Ethernet uplink module with a 10Gb TwinGig Converter module to meet changed network service provision needs. A showcase installation of the new solutions would be at Duke University in the U.S., where it would serve a 27,000 node academic network, Cisco said. The new, higher-capacity Cisco 3750-E switches with 10Gb upgrade capability will be deployed to gradually replace or complement some 1,000 Catalyst 3750 series switches already running the university's student, faculty, and administrative networks. A similar upgrade to an academic network was being considered by University College in London and several other institutions in Europe, Cisco officials said. Duke University and other users would most likely use the 10Gb capabilities to deploy video-based applications and services, they said. Cisco has stressed its support for video and live-image applications. The company is aiming to deliver any video format to any device anywhere on any network built with its infrastructure solutions, said Marthin DeBeer, head of Cisco's Emerging Technologies Unit, at the company's Networkers conference in Cannes, France. In a dramatic example of Cisco's recent TelePresence service, De Beer told conference attendees that his assistant at his San Jose office greeted visitors from a large, high-definition flat video screen while physically present in Dallas -- where the employee had moved. Cisco also announced a showcase installation of its Catalyst 3560 and Catalyst 2960 Compact Switches (for deployment outside wiring closets) on a cruise liner being built in Germany for Aida Cruises. The cruise line, affiliated with Germanyâs Lufthansa AG airline, will install a complete telecommunications and multimedia system based on Cisco infrastructure in all passenger cabins and for crew use on the Aida Diva, a vessel to be delivered later this spring. The services on the Aida Diva would be managed centrally by Lufthansa, regardless of where the ship was cruising, using Cisco's remote network management solutions, said Joerg Liebe, director of voice integration products at Lufthansa Systems. The Aida Diva is the first of four vessels Aida Cruises has on order that will be built with state-of-the art multimedia networks installed by Cisco.

(InfoWorld) - KAMAKURA, Japan -- Mitsubishi ElectricÂ has developed a prototype encryption device that can handle IPsec v2 on 10Gbps Ethernet. The encryption and decryption units are developments on the company's existing hardware for Gigabit Ethernet and were demonstrated here at Mitsubishi Electric's research and development center. The company has managed to increase the amount of data that can be processed each second by expanding parallel encryption of data packets inside the device, said Shinobu Ushirozawa manager of the network security architecture team at Mitsubishi Electric's network security technology department. This was the bottleneck preventing faster speeds, but with 50 parallel data processing units 10Gbps Ethernet is supported. Four encryption algorithms -- AES, Camellia, MISTY and 3DES -- can be handled by the device and two authentication algorithms -- SHA1 and 256-bit SHA2 -- are ready, said Ushirozawa. Mitsubishi Electric has already begun promoting the unit to customers in some industries and is working on an even faster model for 100Gbps networks. Such a device could be available next year, Ushirozawa said. Also on Thursday the company said it has developed four integrated circuits necessary for 10Gbps fiber-to-the-home networks. Currently broadband Internet connections in Japan use 1Gbps access lines that are typically shared between a handful of houses or apartments but carriers are already looking ahead to a next generation service that increases speeds ten-fold. To realize such networks the development of several low-cost components is necessary. Among these are the four chips that Mitsubishi Electric showed as samples. There still remains a number of devices to be realized including new lasers and diodes for both the optical line transmission unit used by the carrier and the optical network unit in the consumer's home. Mitsubishi Electric engineers estimate developments over the next few years will lead to commercialization of 10Gbps fiber-to-the-home in Japan around 2010.
