Recursive Networking
Abstract: Recursion is a fundamental concept familiar in algorithms and mathematics. This talk explores recursion as a fundamental aspect of networking, and developments to support increased cross-section Ethernet capacity and to address routing table growth. We discuss its relationship to multiparty communication and our experience in developing the NSF FIND Recursive Network Architecture (RNA) effort that explores the relationship of layer to protocol and network architecture. RNA examines the implications of using a single, tunable protocol - a metaprotocol - instantiated for different layers of a protocol stack. The RNA prototype extends the Click modular router with control capabilities including dynamic composition and discovery. These capabilities demonstrate how stacks of instances of a single framework support both existing network protocol stacks, as well as new features suggested by virtual nets and the IETF's LISP and TRILL embedded network architectures. We examine, as a result, how - and why - networking may be inherently recursive.
Biography
Joe Touch is the Postel Center Director at the University of Southern California's Information Sciences Institute (ISI) and a Research Associate Professor in USC's CS and EE/Systems Departments. He received a B.S. in biophysics and CS from the Univ. of Scranton in 1985, an M.S. in CS from Cornell Univ. in 1987, and a Ph.D. in CS from the Univ. of Pennsylvania in 1992, joining ISI then. His current projects explore virtual networking, optical Internets, automatic networks, and high-performance zero-configuration network security. He is co-author of a high-speed networks book and chapters on Internet architecture and overlay networks, and has 4 US patents and over 75 conference and journal publications. Joe is a member of Sigma Xi, a distinguished scientist of the ACM, and a senior member of IEEE, and currently serves as IEEE TCCC Chair and on the editorial board of IEEE Network and Elsevier's Journal of Computer and Systems Sciences. He is a member of numerous conference steering and program committees, chairing IEEE CCW 2010 and IEEE ICC FutureNet IV 2011, and co-editing a special issue of IEEE Communications on IETF Standards. He is active in the IETF, creating the "better than nothing security" and recently completed a revised TCP authentication protocol.
