TOKYO, Sept. 29, 2008 (GLOBE NEWSWIRE) -- Internet Initiative Japan, Inc. (IIJ) (Nasdaq:IIJI) (TSE1:3774), one of Japan's leading Internet access and comprehensive network solutions providers, today announced the development of the new SEIL/B1, the latest in the next-generation series of high-performance routers. The new SEIL/B1 will go on sale in November 2008 and will also be available to rent. In advance of its commercial release, the SEIL/B1 will be on display at the CEATEC Japan 2008 tradeshow from September 30 to October 4, 2008 at the Makuhari Messe International Convention Complex.

The SEIL/B1 was designed as a small VPN router that continues to provide all the advanced features of the SEIL series with the addition of multiple ports at a low price. In addition to the Fast Ethernet port, there is a USB port for connecting a mobile data communications card and a BRI port for use with ISDN and other dedicated access services. These additional ports allow for the use of a variety of access lines, which makes this router compatible with a variety of network environments such as redundancy configured networks. The SEIL/B1 is small (250g), has a small space/power requirement, and is compliant with the European RoHS directives, which gives this unit superior environmental performance. It can be used as a low-cost access router at smaller locations and as a VPN router on a multi-location network. It is also compatible with IIJ's proprietary centralized network service management solution, IIJ SMF sx Service, and can also be used as a service adapter for auto-configuration and mobile auto-configuration.(1)

IIJ will continue to actively develop the SEIL/B1 in tandem with IIJ's various network services.
