  1. Network Aware Resource Agent (“Domain Controller”) End to End GMPLS TransportWhat is missing? Border router No standardized Inter-Domain Routing Architecture, including transport layer capability set advertisements Core services, e.g. IP aggregation ala MAX Gigapop IP/ {Ethernet, sonet, wavelength } Core services GMPLS-{OSPF, ISIS}-TE intra-domain routing Optical Core Optical Edge IP/Ethernet campus LAN GMPLS-RSVP-TE signaling Research Activities, e.g. vizualization facilities, computational cluster, data archive No Simple API Integration across Non-GMPLS enabled networks No means for routing all-photonically DRAGONDynamic Resource Allocation via GMPLS Optical Networks DRAGON Participating Institutions: Network Objectives: All optical, metro area core network Dedicated fiber base Optical switches and service modules at key POPs GMPLS routing and signaling Surround the core network domain with participating campus optical network domains These will likely be “carved” from established campus infrastructure and applied to the DRAGON activities. Campus networks will source/sink GMPLS qualified labels (e.g. wavelengths, VLANs, MPLS LSPs, etc.) Support real science applications Integrate DRAGON services into the application environment Interconnect real facilities that require the DRAGON capabilities, e.g. correlators, telescopes, Abilene/HOPI, NLR Mid-Atlantic CrossRoads (MAX), University of Maryland University of Southern California/ Information Sciences Institute East George Mason University Movaz Networks MIT Haystack Observatory NASA Goddard Space Flight Center US Naval Observatory (Wash, DC) University of Maryland College Park NCSA ACCESS Instantiating a Prototype:Optical Services Peering New Technology Development and Deployment Movaz and DRAGON will be deploying early versions of new technology such as: - Wavelength Selective Switching - Reconfigurable OADMs - Alien wavelength conditioning - Tunable wavelength transponders and filters
