Tutorial #4 Tutorial type: half-day (PM ONLY) Author: Wes Doonan, ADVA Optical Networking Title: Dyanmic Optical Network for Grid Computing Description: Ultra-high performance Grid Computing and Distributed Storage applications exhibit an ever-growing appetite for networking bandwidth. As these applications grow wider in scope, this appetite also expands outwards from the campus and into metro, regional and wide-area networks. At the same time, the cost of acquisition and deployment of multi-wavelength, multi-gigabit wide-area optical networks based on DWDM and Ethernet technologies are now within reach of many research and academic users. Finally, direct access to dark fiber and emerging interoperable data-plane standards are enabling direct, usermanaged interconnection of campus or metro optical networks. These parallel developments are finally making possible the establishment a rich collection of truly end-toend, dedicated multi-gigabit services essentially on-demand. The promise is great. However, how are these services to be provisioned, across disparate optical technologies, vendors, and administrative domains? What technologies exist to provision, monitor and account for such services? What does the operator of a regional optical network or Grid Computing cluster need to know in order to participate in the future interconnected optical network? This tutorial seeks to provide an in-depth treatment of the current state of the art in interoperable optical control plane technologies, the practical aspects of deploying such technologies in real networks, and a roadmap for future developments in optical control planes which are expected both in the near-term and on the more distant horizon. Protocols, technologies and concepts are presented in detail, as well as concrete examples of how such technologies can help the user, administrator and operator of Grid Computing facilities provision and monitor their campus, regional and wide-area optical networks.

Discussion Bio: Wes Doonan serves as Director of Control Plane Development for Movaz Networks Inc. Wes oversees the ongoing software development and delivery of optical control plane technologies at Movaz, enabling use of IP-based protocols and techniques to manage large-scale optical network deployments. His group develops core control plane technologies based on GMPLS, ASON and UNI/NNI standards, and adapts them for use with a broad spectrum of optical transport platforms. Wes is a frequent speaker at Internet2 Joint Techs forums on topics relating to control plane technologies for optical networking, and has presented to the NITRD/Jet Forum as well as various CENIC events. Operating out of offices in McLean VA, Movaz provides technical guidance to operators of research and academic networks deploying optical technologies locally and around the world.
