Opportunity
Wave Division Multiplexing technologies
has provided more Bandwidth to transmission systems
than was ever imagined earlier. WDM is a follow on of
SONET and transmits information over Fibre using multiple
wavelength beams simultaneously. Our client, an optical
networking OEM wanted Aricent to design and develop
an Element Manager to manage the Optical Cross Connects
and Multiplexers.
Aricent Solution
The solution-path undertaken by Aricent
to convert this opportunity into a success story comprised
working on an Element Management system based on a distributed
architecture using CORBA and Management applications
being developed using JAVA. The management applications
required software skills in C++ and JAVA and Ilog for
the Graphical User Interface. The other software to
be used in this project was ObjectStore object oriented
database for storage of objects with persistence.
The project challenge was to provide
single point operations access to manage a diverse high-end
optical transmission equipment distributed geographically.
Success Story
This 300 plus person-years project
involved TL1 native agent to CORBA implementation. CORBA
allows distribution of objects and development of distributed
managers that can re-use the same Objects using various
CORBA services. We designed an architecture that provided
for Java applets that can be used from remote locations
for managing the Network Elements. Although the Element
Manager was a Java based GUI application residing over
a CORBA backbone, it also allowed the Network Elements
to be managed by higher level Integrated Network Managers
by providing for TL1 and OSI (Q3) interfaces.
The following are the special technologies
that Aricent has provided expertise for in this project
:
- CORBA based distributed solutions for Network Management
- Tree and Tabular Combined Notation (TTCN) based
Automated Testing Tools
- Telecommunication Management Network (TMN) Q-Adapter
implementation
- Protocol conversion (TL1 - CORBA, TL1 - CMIP)
- Java based client development with CORBA interface
- Object Oriented Database
Some of the other functionality that
were developed for this Manager included: Operator Interface
Management, Geographical map and Topology display, Configuration
Management, Alarm Management, Security Management and
Fault Management.
Despite the fact that the switch-development
was done in parallel with EMS software development,
and market dynamics required changes in function priorities,
the project was completed on schedule. Our client benefitted
not only from reducing their time to market but also
earned laurels from its end-customers-which termed it
as the 'most complete EMS solution'.
