OIF's UNI 2.0 Implementation Agreement Delivers to Emerging Carrier Ethernet Market

The Optical Internetworking Forum has ratified the UNI (User-Network Interface) 2.0 Implementation Agreement (IA), enabling users to signal for enhanced transport services from an optical network service provider. UNI 2.0 complies with the ITU-T ASON architecture, and supports all UNI 1.0 signaling with additional protocol extensions for the following new UNI 2.0 features:

  • Support for Ethernet clients, providing both Ethernet Private Line (EPL) and Ethernet Virtual Private Line (EVPL) services

  • Dynamic bandwidth modification, without service disruption

  • G.709 connection services for ODU and OTU switching layers

  • Low order SONET/SDH connection services

For network users, these improvements deliver more responsive and flexible services plus right-sized bandwidth for their dynamic traffic.

The OIF said these Improvements were gleaned from the OIF's Worldwide Interoperability Demonstration - On-Demand Ethernet Services held last summer between 7 carriers and 8 equipment vendors.
