Project Details

Cisco WAN Manager CWM is a network and element management system that enables operations, administration, maintenance of WAN multi-service networks. CWM has a robust, scalable architecture that meets the demands of end-to-end configuration, fault, and performance management control and operation in very large networks.

Databroker Subsytem

Databroker sub-system consists of two new DMD & sDbroker processes and a legacy dbroker process. Dbroker mananges PVC connections and sDbroker manages SPVC/hybrid connections. Databroker Message Dispatcher DMD reads Equipment manager shared memory messages and dispatch them to legacy DBroker if PVC or new sDbroker if SPVC & hybrid connections . DMD and sDbroker are multi-threaded.

DMD and sDbroker

• Worked on analysis and design of new modules DMD and sdbroker.
• Developed class diagrams and sequence diagrams based on UML methodology.
• Coded DMD and databroker common frame work library
• Implemented communication with Java GUI client is through CORBA.

Dbroker

• Made enhancements to databroker module, which joins and manages multiple pvc segments, to make an end to end connections.
• Worked on performance analysis of databroker, to reduce amount of time taken for sync up , when there are large number of nodes and connections in the network.
• Fixed several critical bugs.
• Provided technical guidance to sustaining team in taking over older versions and mentored new members of the team.

The software system developed for Lucent Technologies project consists of Lucent Pre-Processor. The Lucent Technologies invoice or dunning data is in line-mode ASCII format transmitted over the 128kpbs frame relay circuit. IBS Pre-Processor system will validate and process the input data stream and produce the fully composed AFP data stream to be processed by TC2 and eventually by the IBS factory. The statements will be produced in the IBS factory. Average number of statements processed is 50,000 per month.

• Designed and developed input module to validate and process input data.
• Designed and developed format module, to format the statement, applying, business rules, field formatting rules, section and page breaking rules. And to output AFP tokens and AFP factory NOP records.
• Communication between Pre-processor and TC2 software is implemented
• Developed shell script which is launched by NDM CONNECT:Direct, whenever data appears from Lucent Technologies over the 128kpbs frame relay circuit. This shell script will perform initial validation and start the statement processing.
• Developed Pro*C module to cache the message and insert information stored in the Oracle database.
• Tuned the processor to achieve the processing speed of 60k statements per hour.
• System support and maintenance.
