One of the recent standards flaps in networking is the debate over MPLS-TP versus the older T-MPLS. Standards types can be incredibly obtuse at best, and in arguments they're likely to fall into jargon and acronyms and lose communication with the real world. The publicity on this particular...

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...
