This tutorial will first describe the GMPLS architecture and protocols. This includes a quick review of data-plane technologies, such as SONET, WDM and Ethernet 802.1q VLANs, followed by a more-detailed treatment of the three GMPLS control-plane protocols, RSVP-TE, OSPF-TE and LMP. We will then describe different applications of GMPLS networks, including both commercial, such as fast restoration and rapid provisioning for OPEX savings, as well as research/educational, such as Grid computing, support of eScience projects, etc. Recently, several GMPLS testbeds such as CHEETAH, Dragon, HOPI, UltraScience Net, Ultralight, OMNInet, CA*net4, UKlight, SURFnet, etc. have been created to support science applications. We will describe the goals and accomplishments of these testbed projects. Finally, we will cover some advanced topics such as multi-region networks in which different types of GMPLS networks are interconnected. Security and billing are important issues in today's Internet. We will describe proposed solutions for control-plane security and billing in GMPLS networks.
The presenter, Prof. Malathi Veeraraghavan, is the lead PI of the CHEETAH project, which is a $3.4M NSF-sponsored project to deploy a wide-area GMPLS network in the south-eastern USA. She is currently an Associate Professor in the Dept. of Electrical & Computer Engineering at the University of Virginia. After receiving her PhD from Duke University in 1988, and a ten-year career at Bell Laboratories, she served on the faculty at Polytechnic University, Brooklyn, New York from 1999-2002. She holds twenty-two patents, has over 70 publications, and has received five Best-paper awards. She was the Technical Program Committee Chair for IEEE ICC 2002.
