Chastened and downsizing 3Com Corp, Santa Barbara, California has introduced a new version of its b-router software for its NetBuilder internetworking environment that implements the Intermediate -System -to -Intermediate -System routing protocol for Open Systems Interconnection networks. B-router 2.0 also includes routing capabilities for DEC’s DECnet Phase IV and Novell Inc’s IPX, enabling access to resources on DEC and NetWare networks. The company says that its BR/2000 local b-router and BR/3000 wide area b-router now support DECnet, IPX, Transmission Control Protocol/Internet Protocol, Xerox Networking Software and Open Systems Interconnection. NetBuilder b-router software version 2.0 is currently being beta-tested through-out the US and Europe. One of the beta-test sites, which is currently implementing Open Systems Interconnection on its networks, is Novell’s San Jose, California office. B-router 2.0 is available now from 3Com and from resellers and distributors for $750.
