Communications demonstrate Network-to-Network interface standard for
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
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
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.
