DESCRIPTION: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 resilien
 ce as the ability of the network to provide desired service even when the 
 network is challenged by attacks\, large-scale disasters\, and other failu
 res.  Resilience subsumes the disciplines of survivability\, fault-toleran
 ce\, disruption-tolerance\, traffic-tolerance\, dependability\, performabi
 lity\, and security.  After an introduction to the disciplines and challen
 ges to network resilience\, this presentation will discuss analytical\, si
 mulation\, and experimental emulation techniques for understanding\, evalu
 ating\, and improving the resilience of the Future Internet.  This include
 s a multilevel state-space based approach that plots network service deliv
 ery against operational state that is the basis for both mathematical- and
  simulation-based analysis\, and approaches that embed fundamental propert
 ies such as redundancy and diversity into all aspects of network structure
 \, mechanism\, and protocols.\nA set of tools to help in this analysis has
  been developed: KU-LoCGen (Location and Cost-Constrained Topology Generat
 ion)\, KU-TopViwe (Topology Viewer)\, and KU-CSM (Challenge Simulation Mod
 ule).  Plans to experimentally evaluate resilience include using the inter
 national programmable testbed GpENI:  Great Plains Environment for Network
  Innovation.\n\nBio:\nJames P.G. Sterbenz is Associate Professor of Electr
 ical Engineering & Computer Science and a member of technical staff at the
  Information & Telecommunication Technology Center at the University of Ka
 nsas\, and is a Visiting Professor of Computing in InfoLab 21 at Lancaster
  University in the UK.  He has previously held senior staff and research m
 anagement positions at BBN Technologies\, GTE Laboratories\, and IBM Resea
 rch.  His research interests include resilient\, survivable\, and disrupti
 on tolerant networking\, future Internet architectures\, active and progra
 mmable networks\, and high-speed networking and components.  He is directo
 r of the ResiliNets Research Group\, currently PI in the NSF-funded FIND a
 nd GENI programs\, the EU-funded FIRE ResumeNet project\, leads the GpENI 
 international programmable network testbed project\, and leads a US DoD pr
 oject in highly-mobile ad hoc disruption-tolerant networking.  He received
  a doctorate in computer science from Washington University in 1991.  He h
 as been program chair for IEEE GI\, GBN\, and HotI\; IFIP IWSOS\, PfHSN\, 
 and IWAN\; and is on the editorial board of IEEE Network.  He is principal
  author of the book High-Speed Networking: A Systematic Approach to High-B
 andwidth Low-Latency Communication.\n
