Ipsilon Networks Hosts Multivendor IP Switching Solutions Showcase; Twelve Leading Vendors Demonstrate Interoperable IP Switching Solutions.

PALO ALTO, Calif.--(BUSINESS WIRE)--Sept. 16, 1996--At NetWorld+Interop in Atlanta this week, Ipsilon Networks will host the first public demonstration of a multivendor IP Switched network at the IP Switching Solutions Showcase (booth 762, hall A).

Twelve industry-leading internetworking hardware and software vendors will use the Solutions Showcase to highlight the benefits of the IP Switched network and their respective IP Switching product implementations.

Through the interaction of two simple protocols -- the General Switch Management Protocol (GSMP, IETF RFC 1987) and the Ipsilon Flow Management Protocol (IFMP, IETF RFC 1953, 1954) -- hosts and switches in an IP Switched network freely communicate and cooperate, resulting in a fully interoperable network architecture. Routing decisions are only made once.

When a longer-lasting data flow is identified, cooperating switches cut it directly through the network, without reassembling ATM cells into IP packets at intermediate switch points. Thus, traffic incurs minimal latency, and throughput remains optimized. And because policies naturally span administrative boundaries with cut-through switching, IP Switched networks support end-to-end quality of service.

The IP Switching Solutions Showcase demonstrates how different network elements can implement the IP Switching protocols to deliver ATM-accelerated IP while maintaining multiplatform interoperability. Participating vendors include Advanced Telecommunications Modules, Ltd. (ATML), Digital Equipment Corporation (Digital), Efficient Networks, Ericsson, FORE Systems, General DataComm (GDC), Hitachi Telecom (USA), Ipsilon Networks, NEC America, Network General, RADCOM, and StarBurst Communications.

The IP Switching Solutions Showcase Network

The IP Switching Solutions Showcase includes five separate internetworking scenarios:

IP Switching in the Campus shows how IP Switching solves backbone throughput problems by delivering the speed and performance of ATM while maintaining full compatibility with existing IP hosts and applications.

IP Switching in Workgroups explores how high-end servers, power users, and IP workgroups can connect directly to IP Switched networks to support the throughput demands of bandwidth-intensive applications.

IP Switching in the Internet and WAN features multiple implementations of ATM switches using the IP Switching protocols to accelerate IP data performance throughout public and private carrier-based networks, including the Internet.

IP Switching Broadband Home Access shows how home consumers can use Digital Subscriber Line (xDSL) technology and IP Switches to gain broadband access to the Internet and other IP Switched networks.

Finally, the Network Analyzers and Applications scenario demonstrates protocol-decoding software for IP Switched networks and explores the advantages that IP Switching offers for IP multicast and other IP-based applications.
