Carrier Ethernet work continues for inter-provider connections

Vendors and the Metro Ethernet Forum (MEF) are working to correct an Ethernet omission that may or may not have much relevance to customer interest or service success—the inter-provider NNI. Ethernet standards have not addressed this issue fully because there has been relatively little interest in using Ethernet for long-haul connections, but some believe that the BT interest in PBT for leased-line and frame relay replacement indicate that Ethernet could have a future at a national/international level. This may also spark more interest in pan-provider service management work being done by the IPsphere Forum.

Telefonica has joined the ranks of operators who acknowledge they are testing PBT. As we have indicated, 10 out of 10 of our service provider survey base is conducting or planning PBT tests, but the majority have still not made their commitment public. We believe that there will be five more public announcements of PBT activity among major national providers in 2008.
