Tutorial #1

Title: Hierarchical Routing in GMPLS Controlled and Interconnected Multi-Domain Optical Transport Networks

Presenter: Dr. Fuming Wu, Texas A&M International University

Overview:

The ongoing growth of data traffic demands a robust transport network with increasingly high link capacity and node throughput, while the emergence of new types of network service pushes for a next-generation network infrastructure that can handle traditional best-effort IP traffic together with real-time traffic with assured levels of Quality of Service (QoS). These trends drive the extension of the IP algorithms and mechanisms of MPLS-TE to support non-packet switched interfaces in optical networks. To meet the demand for such extension, the Common Control and Measurement Plane (CCAMP) working group of the IETF has defined the Generalized MPLS (GMPLS) framework. GMPLS relies on a standardized family of control protocols, which includes LMP, GMPLS OSPF-TE/O, GMPLS ISIS-TE, GMPLS RSVP-TE, and GMPLS CR-LDP. This tutorial presents a complete set of mechanisms to support hierarchical routing in GMPLS-controlled and interconnected multi-domain optical networks. While the technical contents delivered in the tutorial originate from core MPLS/GMPLS applications, they span over many topics of general interest to HPSR 2008 attendees, such as routing, traffic engineering, routing protocols and algorithms, protection and restoration, etc. The target audience includes optical networking experts as well as graduate students, engineers, and entry-level researchers.

Dr. Fuming Wu received his Ph.D. degree in Mathematics and Theoretical Computer Science from University of Haifa, Israel. He is now an assistant professor of Computer Science and a certified member of graduate faculty in Full/Doctoral level at Texas A&M International University. His research interests cover theoretical and practical aspects of computer science. He authored or co-authored dozens of research papers published in refereed professional journals and proceedings of international conferences, and holds 17 patents. He has been a member of the technical program committee for numerous international conferences and a peer reviewer for a number of international journals.

Tutorial #2

Title: Networking Virtualization

Presenter: Dr. Omar Cherkaoui, University of Quebec

Overview:

This tutorial provides an introduction to the discipline of network virtualization (NV). While the original application of NV was in the deployment of network services (VLAN, VPN, etc), NV is now being extended to the virtualization of routers/platforms/servers with the injection of multiple instances of such elements in single infrastructural nodes. NV is one of the founding concepts for next-generation networks and the basis for several large research projects (GENI, VINI, VIOLIN). Tutorial attendees will learn about various virtualization techniques (para-virtualization, OS-virtualization, application virtualization, service virtualization, etc.), and virtualization levels. They will associate types of virtualization with isolation levels. They will also be able to evaluate the tradeoffs between performance (latency and
bandwidth) and security (isolation). The tutorial will review existing methods for managing virtual slices and instances, strategies for resilient and reliable migration to virtualized network architectures, and common applications of NV, both commercial (fast restoration and rapid provisioning for OPEX savings) and educational (Grid computing, support of eScience projects, etc.).

This tutorial is intended for researchers (and students) that have interest in the field of network management for virtualized networks. The tutorial/course is also useful to industry professionals that wish to receive a system/technology-based presentation of the current and emerging architectures for virtualized networks.

The presenter, Omar Cherkaoui, received his MSc (1981) and PhD (1988) degrees from the University of Montreal (Canada). He is a Professor of Computer Science at the University of Quebec in Montreal (Canada). He has coauthored more than 50 peer-reviewed technical publications, many invited, keynote, and tutorial presentations, and two patent disclosures. His research interests include network management (standardization, protocols, configuration, validation, modeling, and testing), optical networks, etc. Dr. Cherkaoui is a member of the technical program committees of a dozen network management conferences.
