Carrier Ethernet, Metro Ethernet, PBT
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.
