Additionally, a project on OIF Neighbor Discovery plans to identify discovery requirements by OIF Carriers and expedite the deployments of OIF E-NNI and UNI standards in carrier optical transport networks.
This IA addresses updates for controlling and securing the generation, transport and storage of log data to enable an auditing capability for the OIF's UNI and E-NNI.
Connectivity solutions featured include private E-NNI, Ethernet exchange and white-label approaches.
Further control plane work on new OTN features is in progress under a separate OIF project titled UNI Signaling and E-NNI Signaling/Routing IA - G.
The ability to log signaling and routing messages as they traverse multiple UNI or E-NNI interfaces adds a useful and effective way to help assure correct and secure operation of the signaling and routing entities," said Doug Zuckerman, of Telcordia Technologies and the OIF's OAM&P Working Group chair.
Participating at Verizon's network laboratory (Waltham, Massachusetts) as part of the Optical Internetworking Forum's (OIF) 2009 Worldwide Interoperability Demonstration, Sycamore successfully demonstrated a wide range of Broadband On-Demand test configurations including dynamically switched Ethernet Virtual Private Line (EVPL), end-to-end service restoration using E-NNI (External Network-to-Network Interface) 2.
The test sites are linked via virtual or real E-NNI connections, forming a global test network topology.
Participants are also demonstrating multi-domain end-to-end service restoration utilizing E-NNI between vendor domains.
The new E-NNI implementation agreement and multilayer interoperability are key to enabling end-to-end Ethernet services requests and auto provisioning.
