 Communications demonstrate Network-to-Network interface standard for frame relay  Business Editors  REPEATING...  GERMANTOWN, Md.--(BUSINESS WIRE)--Hughes Network Systems, Inc. and Cascade Communications Corp. today became the first vendors to demonstrate the Network- to-Network Interface (NNI), a Frame Relay Forum standard that enables communication between frame relay devices from different vendors.  Approved last month, NNI provides for the first time, a mechanism for any two frame relay networks to interoperate with each other.  It will enable the creation of one, unified frame relay network, regardless of the service provider or equipment vendor.  NNI will simplify building hybrid private/public data networks, make it easier for users to access long-haul frame relay services via local frame relay services, and permit easy diagnosis and corrections of network problems.  In their demonstration, the two companies established full, bi-directional interoperability between Cascade's STDX frame relay switch and the Hughes FRS 9000 frame relay network.  A key feature of NNI is its ability to address bi- directional procedures for Permanent Virtual Circuit (PVC) management signalling and congestion control.  This means that frame relay service users with devices from various vendors can be assured that congestion problems on the network will not result in data being lost or discarded.  Hughes' FRS 9000 is the cornerstone of the STRATEGY(TM) product line, a complete range of frame relay and X.25 packet exchanges.  All STRATEGY products provide one- for-one redundancy and source dynamic routing, along with full accounting, performance monitoring and statistics.  STRATEGY is a modular and interoperable family of LAN/WAN products that enables users to implement integrated, multivendor networks across international boundaries.  Cascade's STDX frame relay product line brings high- performance switching, rate monitoring, congestion control and LAN internetworking technology to frame relay and wide-area networking. The STDX family enables companies to consolidate multiple networks within a Cascade frame relay network.
