Opportunity
As a part of its full service X.25 private switching and frame
relay network, HNS entrusted Aricent with the software
development and testing of frame relay switch to be deployed
in this network. The FR switch under question had complex
requirements like providing highly reliable packet and frame
transmission and Network access, X.25 devices, such as asynchronous
devices and IBM terminals and hosts. The product line was
to include sophisticated multiprotocol access devices, advanced
Network Management and switching systems.
Aricent's Solution
Aricent involvement in this Frame Relay switch has been in all
the phases of software development life cycle. The major activities
where Aricent contributed significantly included Software Architecture
for new modules; Design and development of various new features;
System and Acceptance Testing for the complete System and
Support and Maintenance Testing for the software releases
deployed in the field.
The Network elements that form a part of Frame relay Network
are, Switching nodes (X.25 or Frame Relay), Access nodes,
Network Control Systems (NCS), and Backbones. The important
modules of this product line include, software development
for Packet switching Cluster (PSC), Network Control Processor
(NCP) and Graphical Network Operator's Console (GNOC). Other
important feature-enhancements included:
- Frame Relay PVC and SVC access
- Proprietary Backbone protocols
- Load Levelling Group
- Call redirect; Call reconnect, re-costing
- Logical partitioning, Source/destination addressing and
VC interrupt
- Support of FR and Frame transparent users on T1/E1 port
- Frame transfer priority with Congestion management and
rate metering
- Frame Network Monitor on GNOC (FRS9000)
- CIR Policing, Call Record, customer billing support &
Quality of service support
- Redundancy/Network reliability with hot plug in feature
- Frame Transparent backbone over ISDN BRI for FRS9000
- Channelised Frame Relay implementation for FRS9000/IX500
product lines with support of FR/FT users on T1/E1 port
Testing activity at Aricent started with the integration testing
of the modules developed by Aricent and the customer. Aricent setup
an independent testing team, which got involved in all the
releases from the initial phases. The testing team not only
dedicates efforts to make sure that it is delivering a good
quality releases but also tried to optimize the usage of resources
and put tremendous efforts to cut down the total testing time.
Success Story
Aricent has played an active role in evolving the HNS'
Strategy (FRS9000) Product line, which implements one of the
most extensive Frame Relay network feature-sets and is deployed
in major networks world-wide. The system level and Acceptance
testing were successfully carried out at customer site with
Aricent engineers participating throughout the testing phase.
Later on with Aricent getting more expertise in the overall system
the complete product line for both Frame Relay and ATM switches
were transferred to Aricent. The complete test bed and all the
hardware and software tools got shifted to Aricent. Then after
the complete software release management gets carried out
from Aricent.
The project successfully demonstrated the world's first implementation
of FR SVCs and involved development of test scripts to emulate
the complete FR signalling functionality on the IDACOM PT500/502.
