Manish Karir, Merit Network

Manish Karir as the Research Program Manager leads the Networking Research and Development group at Merit Network Inc. He is responsible for setting the overall research agenda for the group as well as program management for various projects. At Merit he has led the research activities of Merit in the direction of Internet data analysis and tool development. Some of the successful projects have included the development of BGP-Inspect as a joint project with the University of Maryland which provides a custom backend database that enables fast web based queries in order to extract relevant BGP routing information from vast quantities of raw data; as well the development of a unique software tool called Flamingo that enables Internet traffic data exploration in real-time. Flamingo provides an intuitive 3-dimensional network traffic data representations, as well as the necessary navigation and filtering controls to allow users to manipulate the visual displays. Manish has also been involved with the University if Michigan on the Department of Homeland Security funded PREDICT project, as well as an effort to study, detect, and mitigate the threat posed by Botnets. Based on his research activities, Manish has published technical papers in various refereed conferences or as Merit technical reports, and has often presented his work at these venues. Most recently Manish has overseen the DARPA funded Control Plane program at Merit as well as a project to develop a novel technique for sharing IPv4 addresses.
Abstract: The Internet is rapidly nearing IPv4 address space exhaustion. Current projections predict that within the next two years, all IPv4 address blocks will have been assigned. Various methods such as IPv6 and IPv4 NAT have been proposed to address this scarcity. IPv6 introduces a new set of networking protocols that expands the available number of Internet addresses, while NAT relies on modification of packet headers by the network
to implement IPv4 address sharing. In this paper we present a technique that allows multiple end hosts on a network to share a single IP address by relying on the use of a modified hardware address resolution protocol. Using the proposed approach it is possible to allow thousands of end hosts to share a single IPv4 address and at the same time be able to maintain an end-to-end consistent network.

Our approach is fundamentally different from current techniques, as it does not require that packets from the end-host be modified at the network layer by an intermediate entity as they transit the network. In addition, each end-host
can use a valid routable public IP address. We focus on an expanded use of existing networking protocols such as ARP and DNS to build a novel IPv4 address sharing technique. We have developed an initial implementation of our ideas via a modified Linux kernel which demonstrates the feasibility of our approach.
