(InfoWorld) - A high-tech mecca in Silicon Valley wants to get even more connected by rolling out a superfast fiber network for all its residents. The city of Palo Alto, California, home to many major IT vendors and venture capital firms, last week put out an RFP (request for proposals) seeking a private partner to build a fiber-to-the-home (FTTH) network. The required speed: 100M bps (bits per second) both downstream and upstream. And as debate swirls in nearby San Francisco over how much the city should be involved in a proposed citywide Wi-Fi network, Palo Alto's position is clear: It wants to eventually own the whole fiber network. The drive by some U.S. cities to build their own broadband networks has been attacked by incumbent carriers and other critics who claim governments have an unfair competitive advantage. Many municipalities have taken a different tack by forming partnerships with private network providers. This approach is now under fire in San Francisco, where the city's budget analyst is studying the business case for a government-owned wireless system. City ownership is critical for network neutrality, according to Peter Allen, a founder of the advocacy group Palo Alto Fiber Network. The city understands that having a service provider own a municipal network doesn't work, he said. "If UPS owned Highway 1, FedEx would not be able to make competitive deliveries," Allen said. Existing service providers that might object to the city's plan, such as local incumbent AT&T Inc., can compete for the project along with other private applicants, he said. Palo Alto, a mostly affluent and liberal city of 60,000, already owns several of its own utilities. Its electric utility owns a fiber-optic ring around the city that links to the Palo Alto Internet Exchange, a "peering point" where most major Internet service providers meet on the Internet. In 2000, the city launched an FTTH trial that reached 66 homes and drew rave reviews from users. The city explored having the electric utility build a fiber network itself but found that its plan to pay for it with revenue bonds wasn't allowed, according to the RFP. The council eventually settled on seeking a private partner, then transferring ownership to the city after a few years. How that transfer would work has yet to be determined. At a minimum, the network would provide data, video and VOIP (voice over Internet Protocol) service, according to the RFP. It would be neutral and open to multiple service providers who would buy wholesale access. The city wants services to be affordable and available citywide, though some remote parts of the city might not get the full 100M bps bandwidth, according to the RFP. A service provider would have to come up with just over US$36 million to build the whole network and operate it until it achieved positive cash flow, according to Neil Shaw, a principal at Uptown Services LLC, a Boulder, Colorado, consulting firm the city hired to study the concept in 2002-2003. That estimate included an upgrade after 10 years to provide even greater speed. Uptown estimated revenue from the network would pay off that capital investment within 14 years. The cost of building fiber networks has gone down since 2003, Shaw added. Responses to the RFP have to be in by Nov. 28, and the city plans to identify the finalists on Dec. 18, according to the RFP. The timing of its final choice will depend on what responses come in and how long it takes to review them, said Kathy Bradley, the city's contract administrator.

(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.

Powered Gig Ethernet for Â£30 a port Powered Gig Ethernet just got cheaper. Allied Telesis said its new AT-GS900/8POE switch provides eight Gigabit ports plus a fibre uplink option, all the ports are powered - either eight at 7W each or four at the full 15W - and it's only Â£230, so around Â£30 a port.â¦
