PROTEON ANNOUNCES NEW DECNET/IBM INTEGRATION CAPABILITIES

 PROTEON ANNOUNCES NEW DECNET/IBM INTEGRATION CAPABILITIES
 WESTBOROUGH, Mass., June 15 /PRNewswire/ -- Proteon, Inc. (NASDAQ: PTON) today announced that it has developed a new implementation of its DECnet Phase IV forwarder that enables more comprehensive integration of Digital and IBM environments. The implementation -- incorporated in Proteon's router software -- was based on specifications provided by Digital, verified through Digital's Customer Field Test Process, and is part of the cooperative technology agreement between the two companies announced in September 1991. The new capabilities enable the DECnet Phase IV protocol to operate over the Source Routing bridges found throughout IBM token ring internetworks. These capabilities allow existing IBM token ring users continued use of their Source Routing bridges and unique LAN addressing schemes that many applications require. DECnet-based applications such as PATHWORKS are now better able to traverse existing 802.5/token ring networks. The announcement demonstrates the benefits of the strategic relationship between the two industry leaders for DECnet and token ring internetworking users.
 Proteon's implementation will significantly enhance connectivity in major networking environments such as Fortune 500 companies. "Johnson & Johnson's Consumer Products Division is a token ring installation with over 1,000 nodes operating, and the decision to convert our most important applications to a Digital VAX platform presented an interesting challenge," according to Joe Carella, senior data communications consultant. "Four large sites were already linked with IBM Token Ring Bridges using the Source Routing Protocol, and we wanted to use these same facilities throughout the network. This technology enables us to integrate the DECnet traffic with out NetWare and SNA traffic.
 "Our links via the CNX 500 router give any session access to the full bandwidth available. All sessions -- whether VAX to VAX, workstation to mainframe or PC to PC -- enjoy the maximum available line speed. This is a significant advantage over other currently available solutions, which would require converting to new, more expensive WAN connections," he concluded.
 "Our strategic relationship with Proteon is a key element in Digital's Advantage Network Strategy, providing the flexibility to build enterprise-wide networks with the best available technology," said Gail Daniels, director of Networks Marketing, Digital Equipment Corporation. Delivering New Co-Existence
 Among the new capabilities introduced is the ability for DECnet Phase IV end nodes and Proteon routers to cooperate in "discovery procedures," the method by which a protocol determines the locations of all end nodes on the network and the route by which packets of information find their destination. For the first time, DECnet can now be routed through Source Routing networks because enhancements to DECnet Phase IV incorporate additional discovery features. This allows DECnet Phase IV end nodes to co-exist anywhere within token ring networks connected to Source Routing Bridges. The enhancements enable DECnet Phase IV end nodes and Proteon routers to send information to the appropriate end node, matter where it resides on a token ring internetwork.
 Proteon will also deliver another critical requirement for IBM internetworking, the ability to set a Locally Administered Address. In IBM environments, each end node must be able to retain an independent address assigned to it by a network administrator in order to access an IBM host or utilize protocols such as NetBIOS. This is a "must have" capability in order for end nodes to concurrently run NetBIOS and DECnet. Proteon's CNX 500 and p4100+ routers are the first to meet this requirement in IBM environments, enabling them to adapt address formats to network requirements.
