Abstract

As the Internet becomes increasingly important to all aspects of society, the consequences of disruption are increasingly severe. Thus it is critical to increase the resilience and survivability of the future networks in general, and the Internet in particular. We define resilience as the ability of the network to provide desired service even when the network is challenged by attacks, large-scale disasters and other failures. Resilience subsumes the disciplines of survivability, fault-tolerance, disruption-tolerance, traffic-tolerance, dependability, performability and security. This presentation will provide a brief introduction to the disciplines and challenges to network resilience and to our ResiliNets strategy for resilient network design. Then this presentation will describe the complex multilevel structure of the Internet topology, along with complex-systems analysis and heuristics to improve infrastructure resilience under cost constraints. Then this presentation will describe ongoing work in the design and analysis of a new composable, cross-layered resilient transport (ResTP) and geodiverse multipath routing protocol (GeoDivRP). These protocols are designed to are being developed to provide resilience and survivability in the face of targeted attacks and large-scale disasters to the network infrastructure.

James P.G. Sterbenz is Professor of Electrical Engineering & Computer Science and a member of technical staff at the Information & Telecommunication Technology Center at The University of Kansas, is a Visiting Professor of in the School of Computing and Communications in InfoLab 21 at Lancaster University in the UK, an adjunct professor in the Computing Department at The Hong Kong Polytechnic University and has been a Visiting Guest Professor in the Communication Systems Group at ETH Zürich. He has previously held senior staff and research management positions at BBN Technologies, GTE Laboratories and IBM Research. His research interests include resilient, survivable and disruption tolerant networking, future Internet architectures, active and programmable networks and high-speed networking and components. He is the director of the ResiliNets Research Group and has been PI in a number of projects including the NSF FIND and GENI programs, the EU FIRE ResumeNet project, leads the GpENI international programmable network testbed project and has lead a US DoD project in highly-mobile ad hoc disruption-tolerant networking. He received a DSc in computer science from Washington University in 1991. He has been program chair for IEEE GI, GBN and HotI; IFIP RNDM, IWSOS, PfHSN and IWAN; and was on the editorial board of IEEE Network. He is principal author of the book High-Speed Networking: A Systematic Approach to High-Bandwidth Low-Latency Communication.
