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.
