TOKYO -- Oki Electric Industry Co., Ltd. (TSE: 6703) today announced the launch of its IPGW(R) Series RPR (Resilient Packet Ring) Switch, an optical ring-type Ethernet switch that can construct highly-reliable optical networks at low costs. This switch adopts the latest technology in metro networks; it is fault-resilient and improves communication quality on IP networks. Shipments start today to the worldwide markets.

“This RPR switch can benefit customers, such as telecom carriers and governments that own optical fibers, to construct highly-reliable optical networks at low costs,” said Kazushige Matsui, Executive Officer and President of the System Solutions Company at Oki Electric. “We plan to deploy this RPR switch to self-operating optical network vendors in Japan as well as overseas, particularly towards China where the infrastructure is rapidly progressing.”

RPR switch utilizes the reliability of the fault-resilience in SDH/SONET multiplex equipment, used in conventional network equipment. The switch is based on Ethernet technology and succeeds in enabling a low cost, small size switch. It also responds to IP multicast technology so that it can distribute images economically to multiple locations. When looking at a picture from several locations in the conventional unicast method, lines for each location were necessary. However, with the IP multicast technology, traffic for the one picture diverges and is distributed to multiple locations, which eases traffic congestion and more efficiently uses the network.

With the RPR, users can establish a highly reliable self-operating optical network at a low cost, which will be deployed to vendors around the world with self-operating optical network. Oki also plans to shortly provide a product using RPR technology that has outstanding cost performance features and management functions including fault-resilient solutions, which is challenging in conventional Ethernet switches. Furthermore, it ensures QoS (Quality of Service), including the ability to guaranteeing bandwidth.
