Multi-layer network technology and virtualization pose unique hurdles to resilience, such as ensuring cross layer mappings of links and traffic that are survivable and capacity efficient.   Currently, there is a lack of support for multiple classes of resilient service in existing networks.   This is especially important as traffic that needs high levels of availability makes up only a small fraction of the total traffic volume.  In this talk, we discuss the challenges in providing quality of resilience classes in multi-layer networks, outline preliminary work on a novel cost-efficient approach and provide a framework for addressing these challenges in a multi-layer framework.

David Tipper is an Associate Professor and the Program Chair of the Graduate Telecommunications and Networking Program at Pitt’s iSchool. Professor Tipper's research has been supported by grants from various government and corporate sources such as NSF, ARO, DARPA, NIST, AT&T, and IBM. He is the co-author of the textbook, The Physical Layer of Communication Systems, published by Artech House in 2006 and co-editor of the book Information Assurance: Dependability and Security in Networked Systems published by Morgan Kaufmann in 2008. His current research focuses on resilient network design, energy efficiency, information assurance techniques and time varying network performance analysis.
