Major Accomplishments  Multi-layer call/connection control of UNI-N devices Orchestrates actions between client and server layers Controls Ethernet adaptation using GFP-F/VCAT/LCAS  Creation of end-end calls and connections across: Multiple data plane layers Multiple vendors’ equipment Multiple carrier labs  The major features (1) Ethernet over SONET/SDH adaptation and (2) distributed optical control planes have each been demonstrated before However, this is the first event bringing both together in an integrated fashion on a global scale

Interoperability: Carrier Benefits  Provision end-to-end dynamic connections for flexible data services over multiple, control plane enabled SDH/SONET domains  Deploy at faster pace innovative network technologies  Select cost effective and leading edge network elements, platforms and multi-vendor solutions  Reduce operations overheads and simplify provisioning of new services

OIF and ITU-T Collaboration  Promotes the global development of optical internetworking products  Recognized by ITU-T  Study Group 15 is the focal point for studies on optical and other transport networks, systems and equipment.
