White Paper Cost-Effective, High-Quality, Differentiated Service Bundles Evolve ISPs Executive Summary TRADITIONAL INTERNET SERVICE PROVIDER (ISP) ROLES ARE CHANGING. As basic Internet access becomes commoditized and margins decrease, ISPs must consider building and controlling their own metro and…

…Ethernet is currently under development in the ITU (Y.1731), the IEEE (802.1ag and 802.3) and MEF (MEF10/16). Connectivity OAM---as viewed by the service provider and network operator---is primarily supported by ITU-T Y.1731 and IEEE 802.1ag. The IEEE 802.3 Ethernet in the First Mile (EFM) standard (formerly…
