Location: Sunnyvale, California, United States Profile: https://flows.cv/vijayabhaskar 12 years of design and development experience in the Internet protocols, Data Center Switching, Load Balancers, Intrusion Prevention Systems. Experience in developing scalable control plane for Juniper's next generation large scale distributed Data Center Switch called QFabric and hands on experience in High Availability (HA) and Restartablity of control plane modules Hands on experience in routing protocols: BGP and ISIS Experience in developing kernel modules in FreeBSD for multi-core platforms. Hands on experience with design and development of Load Balancers. Experience in Intrusion Prevention Systems. Worked on developing a light weight IPv6 stack to detect attacks in IPv6 packets in McAfee's Intrusion Prevention Systems. This included implementation of IPv6 fragmentation/re-assembly, IPv6-in-IPv4, IPv4-in-IPv6 tunneling and enhancing TCP/UDP layer to support IPv6. Designed and Implemented a highly scalable DHCPv6 server in HP Unix. It is one of the earliest implementation in the world. Experience in writing multi-threaded applications. ## Work Experience ### Senior Rocket Scientist @ Rocket Fuel Inc.
