- Offers Comfortable Connection Environment for IPv6 Users -

OKI Electric Industry (TOKYO:6703) today announced it has added new functions to its security gateway “CenterStage® NX4300” which is equipped with a translator function to allow communications over different protocols, such as IPv4 and IPv6. The newly added functions include a session assurance function and premium forwarding functionality to ensure flexible user service level. These functions enable interwork between IPv4 and IPv6 and create a comfortable connection environment for IPv6 users. The product will be sold to telecom carriers in Japan using IPv6 from September 2009.

“It is expected that the inventory of IPv4 addresses will be depleted in the coming years, and as a countermeasure, it has become important to shift to IPv6. However, during the transition period, it will be necessary to implement measures to extend IPv4 network lifetimes while establishing new IPv6 networks, achieve interworking among them, and minimize the quality deterioration while interworking,” said Hidetoshi Saigou, General Manager of Carriers Business Division at OKI. “By adding two new functions to our NX4300, we believe we can offer a great connection environment to users while contributing to the smooth transition to IPv6.”

OKI’s NX4300 is a carrier-grade security gateway with a translator function to enable interwork between IPv4 and IPv6. The system adopts the ATCA(1) platform and network processor, achieving carrier-grade translator capability with high-speed processing and high-availability. OKI added a session assurance function to ensure flexible service level for users using IPv6 devices and a premium forwarding function to enable high-speed forwarding of large capacity rich content, enabling interwork between IPv4 and IPv6. In addition, the gateway offers a better connection environment when IPv6 users access existing IPv4 network resources and data center resources, because it can preferentially convert protocols and enable high-speed forwarding depending on the service level, even when the network load is high.

Going forward, OKI will enhance the function of its NX Series as a security gateway and contribute to the smooth transition to IPv6 by adding an IPv6 security function and a DPI (Deep Packet Inspection) function to accommodate the full-scale expansion of NGN(2).
