Xantium IP Network Management Software, USA

Wipro Technologies Chennai, India

July 2000 - September 2000

Sr. Test Engineer Software

 

The main idea of this project is to configure and manage The Xantium NE is through a Command Line Interface (CLI), which is a simple set of typed commands entered via an ordinary telnet session. For the Xantium we used a Third-party product to implement this feature: Rapid Control for CLI (RCC) from RapidLogic. The set of CLI commands for the IP applications, i.e. IP forwarding, MPLS, RSVP, OSPF, BGP, ISIS, RPIF and QOS. The CLI commands are entered in a telnet session, and parsed by RCC. If the command matches with a defined command, the parameters are mapped onto MIB objects; an SNMP message is generated and sent to the master agent. The master agent forwards the message to the proper SNMP sub-agent, which updates the configuration in the database and towards the software application, or reads out the requested MIB objects for a display in the telnet session.

 

Responsibilities:       

 

·   Coding and Unit Testing using C Language, RAPID Control for CLI (RCC).
