Element management system gateway
on TMF 814 framework for optical network elements
The client
Leading North American equipment
vendor.
Problem
Due to the
economic slowdown the company was looking
at cutting costs. They were looking for outsourcing
partners for implementing the new features
in the product.
The gateway
module needed expansion as more and more customers
had started integrating the EMS application
with their OSS and subsequently asking for
more features.
Project challenges
The gateway
team had to directly work in the on-going
release for developing some features when
the team was initially being setup
Due to specialized
skill requirements, finding the right resources
was a challenge for Wipro as it was for the
customer. The requirements for more resources
are of immediate nature
There were
very few people who knew about the gateway
modules
The customer
did not mandate the quality processes
and did not estimate for them
Solution
Gateway team
learnt about the Element Management System,
the TMF 814 interfaces and the development
procedures followed quickly for successfully
delivering the assigned tasks
Wipro had
buffered suitable candidates and gave some
exposure to the modules where the resource
requirements were likely to come up
Wipro took
ownership of the two modules. This extended
to the developing features & bug fixing
in the entire modules
Wipro engineers
stretched to follow the quality norms
Benefits
Wipro Gateway
team had worked on fault, configuration, performance
& security interfaces and overall added
28 new APIs in a span of 3 releases of the
product. Most of these APIs were supported
for more than 4 different types of Network
Elements (NEs). These APIs were either TMF
2.0 defined or custom defined for some specific
requests from customers
Apart from
the new APIs mentioned above, new NE type
,a new NE release support for the existing
APIs and new parameter support in the existing
APIs were done by Wipro for the 3 releases
of the product. The existing APIs supports
were extended to about 10 new versions of
NEs by the Wipro team. About 46 APIs were
modified by the Wipro team to add new functionality
into the APIs
Wipro team
implemented the upcoming TMF concept "FTP"
to model the termination points that did not
fall under standard PTP & CTP models that
are defined in TMF 2.0. About 20 APIs supported
by the product use this concept now
Other business/Technical benefits
There was a very good
response from the customers of the product who had
been using the gateways for integrating with their
OSS applications. Some customers started using
it even without a single issue and even without
contacting the support team even once.
