The Optical Internetworking Forum (OIF) is hosting a “Worldwide Interoperability Demonstration – On-Demand Ethernet Services” to showcase interoperability in a multi-carrier environment. 
Participating vendors include Alcatel-Lucent, Ciena Corporation, Ericsson, Huawei Technologies, Marben Products, Sycamore Networks, Tellabs and ZTE.
Participating OIF Carrier members include AT&T, China Telecom, Deutsche Telekom, France Telecom Group, KDDI, Telecom Italia and Verizon.
OIF participating members are demonstrating end-to-end provisioning of dynamic switched Ethernet services over multiple, control-plane enabled intelligent optical core networks through the use of OIF implementation agreements UNI 2.0 and E-NNI including:
- Ethernet Private Line – allowing carriers to leverage existing TDM infrastructure to carry Ethernet
- Neighbor Discovery – automating what is currently a manual provision process between neighbors
- Control Plane Failure Recovery – an important carrier-class reliability feature
- Non-Disruptive Bandwidth Modification – optimizes network operation and resources by adapting to bursty data traffic flows.
The test phase of the event has been underway in Carrier labs since June 2007. The event will culminate in a public demonstration of the results at ECOC 2007, September 17-19, 2007 in Berlin.
