Wipro undertook
a comprehensive requirement analysis and proposed
a scaled down version of NMS which could be developed
in client’s limited budget. The key features
of product are
 |
The communication
is only one way from EML(s) to NMS. Any action
required in the southbound direction is prompted
to the operators in the form of work orders |
|
NMS provides operations
such as add/remove/update circuits and issue
work orders which can be assigned to individual
operators. Operators either need to take action
on EML(s) or in the field (for physical links) |
|
NMS provides Auto-discovery
of end-to-end circuits |
|
NMS collects alarms from
underlying EML(s). Correlation of EML alarms
to circuit alarms is done and data is maintained
in the NMS database. It provides filtering
and sorting criteria for reporting circuits
and displays the circuits affected by alarms |
|
NMS retrieves the QoS
parameters (PDH) from EML. Based on available
PM data and the circuit data in the database,
end-to-end QoS is calculated. Its also generates
a report that describes the performance of
the circuits in a quantitative way for a certain
time range |
The NMS is intended to support 50K end-to-end
circuits. It is completely developed in Java and
is supported on both HP and Linux platforms. NMS
architecture is distributed, having the Oracle
database, main NMS software and the UI running
on different machines and platforms. Operators
can remotely access the NMS software through a
browser.
Wipro has been involved right from formulating
requirement specification to system integration
testing with the EML(s). As of now inventory and
alarms module implementation is completed and
performance monitoring and final integration testing
is pending. Total size of the code is 40K.
