ECMP routes to Kernel:Duration: 1 monthsResponsibility:Add code to support adding ECMP routes learned from Routing protocols of the network stack to Kernel using NETLINK socket.ISSU for BGP:Duration: 8 monthsResponsibility:Design and make changes to the routing protocols to support ISSU, using existing infrastructure.Test the complete solution. Analyze the issues found, fix the issues or work with the infrastructure and silicon integration teams in getting them resolved.Come up with solutions for complex time critical issues.Scaling 256k BGP routes for new supporting hardwareDuration: 6 monthsResponsibility:Make changes in the code to allocate dynamic memory instead of pre-allocation of memory.Add templates to support scaling for 256k routes.Change code to use locks for CLI calls instead of using message queues.Change code to gracefully handle malloc failures.Scale routes to 256k with all necessary memory tunings.Test the changes made and fix the bugs found. Linux ARP integration into network protocol stack Duration: 1 monthResponsibility:Design and develop code to integrate Linux ARP into protocol stack, using netlink sockets.

Hyderabad Area, India

Worked as Contract Software Engineer for NWSOFT (Network Software) division of ING (Infrastructure and Networking group) at Broadcom. VRF-Lite :● Implement Ping as a separate process to make use of Linux network name spaces enablingPing feature to be used in VRF-lite environment.● Create the configuration parameters for the OSPF process, using the proprietary IPC (socket)mechanism.● Handle the changes made to the configuration in the OSPF process and implement code toset and get the configuration from CLI.● Fix the defects (mostly OSPF process specific) and maintain the feature.Static IPv6 Neighbors :● Device the requirements and come up with Functional Specification for the feature. ● Design, implement and test the feature.● Fix the defects and maintain the feature.Ping Enhancements :● Add more functionality to IPv6 ping by providing options like interval, count and sourceoptions. Involves re-design of the existing functionality.● Improve the efficiency of IPv4 ping by making several changes to the code and also addService port and network ports to source options.DHCP Client Identifier (Option 61) :● Device the requirements and come up with Functional Specification for adding DHCP Clientidentifier option.● Design, implement and test the feature.New Platform Bring-up :● Develop drivers in application for I2C devices like FAN Speed regulators, LEDs, Power Modules and Temperature Sensors for a new platform.● Write code to control the FAN speed with changing temperature based of the switch’s thermal curve.● Merge the necessary uboot changes from ODM to the code base.● Debug and fix defects in uboot related to I2C devices.● Debug and fix issue in Linux code. Spent considerable time in finding out the rate-limiting flags, enable them and test if packets received on the service port or OOB interface are rate-limited.● Perform several tests on the new platform including Snake test and help QA team to bring up dead DUTs.

FIP Snooping :● Develop the CLI, SNMP and traps for the FIP Snooping feature.● Test the commands● Make the required setup for testing FIP snooping which includes bringing up servers, Linux systems and storage devices.Other Activities: ● Responsible for maintaining testbeds used for running the automated test cases to find breakages at the early stages in development phase.● Responsible for the lab resources required by the team.● Worked on Smart platforms with low footprint. Tested the functionality and fixed several issues found during the test phase. Some issues involve changes to the Web UI.● Resolved the baud rate issue on a platform; making it to work dynamically at any of the two different configurable CPU speeds. ● Involved in addressing issues found, by static analysis of the code using coverity tool.● Resolved the crashes and hangs found on the several platforms.
