OIF UNI and NNI, combined with GMPLS and ASTN enabled transport networks, allow rapid end-to-end connection provisioning
Most efficient data over SDH/SONET transportBased on ITU-T Standards
ASTN/GMPLS network
Decoupling of the data NE interface rate with the bandwidth of the connection in the transport network
Most efficient mappingof Ethernet in VC-x/STS-y;payload is transmitted only

Feedback
Performing the next step, after specification, is of paramount importance for carriersThese tests results are building the basis for:• Further activities, e.g. evaluations, field tests, pilots;
these steps are definitively needed on the roadmap towards implementation
• Design of new network servicesGetting a world wide overview of the status of interoperable implementationsClose cooperation with interoperability tests partners, carriers and vendors, giving manifold opportunities for upcoming OIF activities
