•Performed risk analysis on the networks of clients viz. Microsoft, Time Warner Cable, etc. to help run the network seamlessly during hardware migration to ASR9K series routers• Worked with on-site service engineers to troubleshoot anomalies arising during IOS-XR upgrades in the client’s network during an upgrade or migration in the customer’s network• Recommended more stable software packages to the client depending on the impact caused by defects in a customer’s network• Highlighted probable issues and suggested workarounds for the same to clients using Cisco’s IOS-XR releases

• Implemented three TCP protocol variants Tahoe, Reno and New Reno in a discrete event simulation software called NetSim according to the guidelines mentioned in RFC 793, RFC 2001, RFC 2581 and RFC 2582• Developed backend code of three congestion control algorithms- Fast Retransmit, Fast Recovery and NewReno's modification to Fast Recovery in C• Responsibilities include testing of other network protocol simulations in NetSim like GSM, CDMA, Zigbee andMANET. The test simulations were run using shell scripts• Co-Authored a white paper which analyzed the throughput and congestion window behavior of the above- mentioned TCP variants in NetSim (tinyurl.com/hcpqwmy)
