Single layer versus Multi-layer recovery techniques in Core Networks
A plethora of Network recovery techniques have been designed over the last two decades at multiple layers: Optical, ATM, SONET/SDH, IP/MPLS. Although such techniques are usually evaluated from the angle of rerouting times, there are undoubtedly many other metrics that should be taken into consideration such as the required backup capacity, scope of recovery, scalability, required number of extra states, backup path quality of service to mention a few. The combined used of these technology is also an option although such combination unavoidably leads to more complex network designs and inter-layer recovery interactions that may have a direct impact on the ease ability for Service Providers to manage their network. The aim of this panel is to discuss the state-of-the-art of several single-layer approaches but also several possible multi-layer recovery scenario and get the views of various experts in the field on this crucial topic for voice, data and video networks.
 
Panelists
 
JP Vasseur - Cisco Systems (Panel Chair).
JP Vasseur is a Cisco Distinguished Engineer where he works on IP/MPLS architecture specifications, focusing on IP, Traffic Engineering, network recovery and Sensor networks. Before joining Cisco, he worked for several service providers in large multiprotocol environments. He is an active member of the IETF, co-chair of the IETF PCE (Path Computation Element) Working Group and coauthor of several IETF RFCs. JP is a regular speaker at various international conferences and is involved in various research projects in the area of IP and MPLS. He has also filed several patents in the area of IP and MPLS and is the coauthor of �Network Recovery� (Morgan Kaufmann, July 2004) and �Definitive MPLS Network Designs� (Cisco Press, March 2005).
 
Emmanuel Dotaro, Alcatel-Lucent, France
Emmanuel received an M.Sc degree in Computer Science from the University of Versailles, France in 1996. He spent 3 years in the Performance Evaluation Laboratory of Institut National des T�l�communications. While holding a teaching position at the University of Versailles, he then joined in 1999 the Alcatel Research and Innovation Laboratory at Marcoussis, France. He is now managing the strategic research project Packet Transport Infrastructure, France as he was previously leading for six years the control and management plane activities. His current research interests are network architecture and design, control and management including self-management and focus on protocol suites such as MPLS/GMPLS, PCE, LxVPN.
Emmanuel participated in or led several national and European research projects and he is the author of more than 30 patents as well as research communications including highly-selective conferences, journals and magazines. Since 2001, he is actively participating in standardization bodies, in particular IETF.

His is a member of the new BONE European Network of Excellence (NoE) and the French representative of the European COST 291 action on Optical Digital Networks. He has authored or co-authored about 120 technical papers in IEEE or IFIP conferences or journals. He is the author of a book in English on broadband access systems (Artech House, 2003) and of three books in French. A new book written with two of his former PhD students titled �From network planning to traffic engineering in translucent optical WDM networks� will be edited in 2007 by Springer-USA. He has participated in the writing of three collective books in English on ATM networks (Kluwer, 2000), on IP over WDM (Addison-Wesley, 2002) and on optical traffic grooming (Springer, 2007). He has chaired the IEEE Globecom 2006 Symposium on Advanced Technologies and Protocols for Transparent Optical Networks.  He is in the steering committee of the IEEE-IFIP ONDM and IEEE HPSR conferences, and in the TPC of several IEEE or IFIP conferences. He has been appointed as an expert by the Flemish Government of Belgium (1998) and the National Science Foundation of the USA (2001, 2004). He is a member of the Optical Network Technical Committee of the IEEE and of the IFIP WG6.10 working group on photonic networking. He is graduated from INT Evry-France. He received the DEA degree from University Paris 6, the Ph. D. degree from ENST and the Habilitation from University of Versailles (1999).
