KDDI again taps Corrigent for metro expansion
June 1, 2005 San Jose, CA -- Corrigent Systems' CM-100 Packet Add-Drop Multiplexer (ADM) platform was selected by Japan's KDDI for furthering the expansion of the carrier's packet-based metro transport network. KDDI will use the 10-Gbit/sec multiplexer platform for the second phase of the network's deployment; the first phase, announced last year, included over 1,000 units of the platform, and is now carrying commercial traffic, according to a press release.
Corrigent says its CM-100 combines RPR (IEEE 802.17) with Ethernet and MPLS technology to enable a metro transport platform optimized for video, voice, data, and TDM services. The company says that quality of service and resilience are critical features of the platform, ensuring that service level agreements promised by carriers are enforceable.
For video services, the platform incorporates multicast functions that reduce the bandwidth required for video broadcasts by an order of magnitude, according to the company. The platform also offers statistical multiplexing to allow service providers to reclaim and resell unused bandwidth during periods of low network traffic. Together, the company says these features will allow KDDI to offer more bandwidth at competitive rates.
"We are pleased with Corrigent's ability to meet our aggressive rollout goals for the first phase of network buildout, and are confident that Corrigent will successfully support the continued rollout of the competitive network we designed," comments Seiichi Aruga, head of the transmission networks planning section at KDDI's optical engineering division.
"Corrigent's Packet ADM allows carriers such as KDDI to build a metro transport infrastructure optimized for packet transport, that is scalable to meet the surging bandwidth demand associated with triple-play, wireless and business Ethernet services," adds Ehud Rokach, CEO of Corrigent.
The carrier's packet-based metro network is designed to support triple-play broadband as well as 3G cellular telephony services.
