T1. Capacity Constrained MANETS: Adaptive Policy-Driven Fault and Performance Management
by
Latha Kant , Telcordia Technologies, USA

Characterized by their flexibility to be deployed and functional in “on-demand” situations, combined with their capability to transport a wide spectrum of applications and resilience to dynamically ‘heal’ around failed network elements, mobile ad hoc networks (MANETs) are gaining rapid momentum both in the commercial and military arenas. Illustrative examples in the commercial sector include the need for establishing communications in disaster areas and/or rural places where it becomes difficult to deploy fixed infrastructures.  In the military sector, MANETs are becoming the basis for the future network-centric warfare (NCW) paradigm as exemplified by the Future Combat Systems (FCS) and Warfighter Information Network-Tactical (WIN-T) programs.   The success of MANETs is however critically tied to their capability of transporting a wide spectrum of applications with varying quality of service (QoS) requirements or service level agreements (SLAs), and providing continued/un-interrupted service (i.e., seamless recovery) despite failures in the underlying network.

Dr. Latha Kant (Ph.D., Electrical and Computer Engineering) is Senior Scientist and Director of the Mobility Management research group in Applied Research at Telcordia Technologies, where she has been working since 1996. Her research interests and expertise span wireless ad hoc networking and network management, as well as performance modeling and analyses of MANETs. She has led and managed several research projects at Telcordia. Currently, she is the technical lead of the QoS team within Telcordia’s Future Combat Systems (FCS) program, where she is leading a team of researchers to develop end-to-end QoS solutions for heterogeneous multi level security networks. She has also led several projects on MANET performance modeling and analysis including Telcordia’s internal research and development efforts on scalable mechanisms for MANET performance analysis and the CERDEC DRAMA sub-task on scalable modeling and analysis of a dynamic policy-based network management system for MANETs.  Dr. Kant is also currently leading a research effort on Network Science as part of the Army Research Laboratory (ARL) Communications & Networks (C&N) task on Survivable Wireless Mobile Networks (SWMN) with a focus on fundamental research in the area of MANETs.  Prior to joining Telcordia Technologies, Dr. Kant worked with the communications systems division of the India Space Research Organization (ISRO), subsequent to completing her Bachelors of Engineering in Electrical and Electronics Engineering. As a research scientist with ISRO, she was part of the team that designed on-board and ground communications systems for satellite networks. Dr. Kant has published over 40 papers in journals and conferences, and holds a patent on self-healing mechanisms in packet-switched networks.  Dr. Kant is a member of Etta Kappa Nu, Engineering Honors Society.

T2. Challenges in Network Virtualization
by
Omar Cherkaoui, University of Quebec at Montreal, Canada

This tutorial provides an overview to the discipline of Network Virtualization (NV).   Previously, Network Virtualization has consisted in deploying network services (VLAN, VPN, etc) and today it has evolved in the deployment of multiple distinct networks over the same physical infrastructure. Each network instance requires a level of isolation from the other instances. This isolation uses some old OS concepts of virtualization like: Hypervisor (VMM) and Containers. Furthermore, those concepts use an independent layer for the control and sharing of resources like network links, CPU, memory, interfaces, etc.

Virtualization has emerged as an active research area. Many large research projects (GENI, 4ward, Federica, Clean Slate, Horizon, JGN2 Japan) have been launched during the last two years. Those initiatives mainly try to develop the next generation network based on the network virtualization concept.

Dr. Omar Cherkaoui received his M.Sc. (1981) and Ph.D. (1988) from the University of Montreal (Canada). He is a Professor of Computer Science at University of Quebec in Montreal (Canada). Dr. Omar Cherkaoui teaches computer networks and distributed systems and conducts research in the area of network management and virtualization. He has published more than 100 papers in refereed journals and conference proceedings. He has authored multiple invited, keynote, and tutorial presentations, technical reports, and two patent disclosures. He worked during four years as a researcher at Cisco where he developed configuration and automatic test case generation solutions for the 12000 series.  He participated to many industrial projects with companies such as Norlel, Bell, Telus, Hydro, etc. He created the research laboratory in computer networks (Lab Téléinformatique) where he supervised dozens of projects in the domain of hi-speed network management, Web services platform and new multimedia software (UCLP, Validmaker, Articiel, BIOGRID,..). His research interests include network management (standardization, protocols, configuration, validation, modeling, testing), optical networks, etc. Omar is a member of the technical program committees of a dozen network management conferences.
