Opportunity
The Aricent's FRASM project came as an opportunity for Aricent's to
experience new product development in high technology areas.
This particular product family demanded a full range of frame
relay and ATM equipment interconnection, spanning campus and
wide area applications by using private lines and/or public
ATM services.
Aricent's Solution
Aricent's had the complete responsibility for the delivery of the
Frame Relay Adaptation and Switching Module and was responsible
for architecture designs, hardware and software design of
the components, network design, protocol design, design and
implementation of drivers, diagnostics and provide support
for operating system services.
The Aricent's developed ATM switch could support
networks comprising Broadband Swicthing nodes, Interface Switching
nodes Remote frame relay access devices. The protocols supported
by this network would include protocols such as X.25, SNA/SDLC,
IP over Ethernet or Token Ring, ATM, unstructured T1 or E1
circuit emulation and Frame Relay over ATM backbones, Frame
Transparent over frame relay trunks over a wide area network.
All the different network elements are managed by a single
network management system.
The product is provided with a comprehensive package of network
management tools, supporting and enhancing its basic functionality.
The network management functionality includes:
- Use of HP OpenView (HPOV) to allow integration of network
management applications with third party network management
applications
- Avoidance of proprietary network management in favor of
widely used standards, such as SNMP, allowingwide access
from non-proprietry network management products
- Extensive use of user friendly Graphical User Interfaces,
for example, the drag-and-drop creation paradigm
- Provision of FCAPS -Fault, Configuration, Accounting,
Performance, and Security features.
Other important services which Aricent rendered included defining
the Software Architecture for the FR adaptation and switching
module, designing the hardware architecture, component selection
and simulation/benchmarking for the switching modules, Connection
management - establishment, maintenance and release of FR/ATM
connections, Switching of incoming FR traffic to outgoing
ATM VC (one-to-one multiplexing and one-to-many multiplexing
modes), Implementation of policing and traffic shaping of
incoming FR traffic and outgoing ATM traffic Design
In the testing sphere, Aricent was primarily involved in the
Design Verification Testing and Hardware Verification Testing
(HVT) for the ATM UNI Adaptation and Switching Module and
the Frame Relay Adaptation and switching modules.
Success Story
The Frame Relay Adaptation and Switching Module provided non-ATM
Frame Relay access on the ATM backbone switch. The HNS award
winning ATM Network Switch (BX5000) is used as enterprise
wide area backbone network for data, voice and video applications.
Full redundancy, hot swappable modules, robust permanent virtual
connection routing and state-of-the-art network management
ensure that mission critical applications are not interrupted.
These Frame Relay switches have been deployed in more that
50 countries all over the world. One of the deployments crossed
200 switches in a single network. Most of these networks are
being used heavily on daily basis for banking/financial transactions,
government transaction, Internet and for various other real
time applications.
