Sanjay Khanna, Foundry Networks

Sanjay Khanna is a senior product marketing manager in Foundry Networks Service provider Systems business unit. In his role, Sanjay is responsible for product strategy of the Foundry Networks XMR/MLX series of IP/MPLS Routers. Sanjay has over 14 years of experience in the design and development of next-generation IP, MPLS, Ethernet and ATM switches and routers, and has worked with multiple service providers in designing next generation MPLS, IP, Ethernet, wireless backhaul and triple-play networks. He has held numerous leadership positions in product management and engineering at Tellabs, Vivace Networks, Mariposa Technology and Newbridge. Sanjay holds B.E and M.E degrees in electrical engineering from Concordia University in Montreal, and a MBA from University of California at Berkeley.
Abstract: Currently, network operators are increasingly bundling multiple links together to meet the growing demand for IP and MPLS services. They also use several Equal Cost Multi-Path techniques at various protocol layers such as BGP, OSPF, ISIS, RSVP-TE and LDP to provide multiple paths. This leads to numerous combinations of load balanced paths at different layers (IP, MPLS, Ethernet). With services being offered for native IP, L2VPNs, VPLS, L3VPNs, IPv6 and others, a one size fits all approach for load balancing is limited. In this presentation, we will look at the reasons for load sharing, the various layers where load sharing is used, highlight the criteria used for load sharing at each layer and recommend the best schemes to be used for each traffic type to boost network capacity utilization. We will further look at some interesting techniques of speculation in MPLS packets and neutralization of polarization effects in IP networks.
