PROTEON EXPANDS ROUTER FAMILY TO INCLUDE THE HIGH PERFORMANCE CNX 400 REGIONAL-SITE SOLUTION

 WESTBOROUGH, Mass., Aug. 16 /PRNewswire/ -- Proteon, Inc. (NASDAQ: PTON), manufacturer of industry-leading SNA internetworking products, today announced the Corporate Network eXchange (CNX) 400, a mid-range solution in its RISC-based CNX family of multi-protocol bridging routers. The CNX 400 is designed specifically for large remote or regional sites. Supporting up to three LAN or six WAN ports with one FDDI connection in flexible configurations, the CNX 400 router offers powerful, cost-effective connectivity with a throughput rate of 25,000 packets per second. Proteon will also deliver an ATM interface card for the CNX router family in 1994 and will incorporate a Cell Switching Fabric in its next-generation bridging router to enable efficient packet routing.
 "The CNX 400 is the most attractive solution in the mid-range internetworking category because of its software features that enable simple configuration and maintenance across the backbone, its interchangeable I/O cards with the CNX 500 and CNX 6 extensive SNA/LAN interconnect capabilities," said Gilles-Andre Morin, technical architect at Montreal-based SHL Systemshouse, Inc., a worldwide, billion-dollar systems integrator that implements several CNX 400s in its own network.
 The three-slot CNX 400 can be flexibly configured for Ethernet, Token Ring and FDDI. In addition, the CNX 400's interface cards are the same as the cards in the headquarters CNX 500 and CNX 600 allowing for cost-effective, centralized management, card sparing, inventory control and decreased training costs. As part of a consistent software set in all Proteon routers, the CNX 400 supports 18+ protocols via Transportable Software Architecture (TSA), and ensures predictable response time for mission-critical SNA applications through the Bandwidth Reservation feature.
 Proteon's Bandwidth Reservation is the industry's only guaranteed bandwidth allocation technology. By assigning bandwidth based on the users' specific protocol patterns, Bandwidth Reservation provides network managers with the ability to ensure predictable response time for application classes, such as SNA, in a fully-loaded network. Bandwidth Reservation assigns minimum guaranteed bandwidth with 1 percent granularity and four priority levels for each specified class (urgent, high, normal and low), which does not permit protocol bandwidth "hogging" that contributes to session time outs.
 "We have provided a feature-rich solution for the growing mid-range internetworking market by delivering the high performance and competitively-priced CNX 400," said Karyn Mashima, vice president of corporate marketing. "The CNX 400 rounds out Proteon's multi-protocol router product line satisfying requirements at mid-range-sites of large enterprises, especially those consolidating SNA traffic," she said.
 Available today, the CNX 400 is priced at $3,995-$11,195, depending upon configuration. Proteon's complete line of routers includes the RISC-based CNX family -- the headquarters CNX 600, the regional/divisional CNX 500 and the new CNX 400 mid-range ro announced today -- and the award-winning Departmental Network eXchange (DNX) 300 family of branch office routers -- the DNX 300i for IBM environments, the DNX 300n for Novell sites and the DNX 300m for multi- protocol environments. All routers are managed under OneVIEW/pc and OneVIEW UNIX with SNMP-supported MIBs to IBM's NetVIEW 6000 and HP's OpenVIEW.
