The Metro Ethernet Forum introduced a set of “Carrier Ethernet 2.0” specifications aimed at revolutionizing the efficiency and usability of Ethernet service delivery through the addition of three standardized features: Multi-class-of-service (Multi-CoS), Interconnect and Manageability.
Carrier Ethernet 2.0 is defined by its ability to deliver differentiated applications over interconnected, managed networks globally. Whereas the first generation of Carrier Ethernet standardized E-Line and E-LAN services, CE 2.0 standardizes Multi-CoS over eight interconnected services, including two versions of E-Line, E-LAN, E-Tree and E-Access.
Newly defined Multi-CoS extensions will now ensure standardized performance objectives across geographic boundaries, resulting in improved QoS and optimized efficiency on a global scale. New interconnect specifications extend the reach between carriers, and new management specifications provide scalability and measurability not previously possible. A new Mobile Backhaul Implementation Agreement creates a standard for 4G mobile backhaul services through Multi-CoS-enable interconnects.
The Metro Ethernet Forum cited several benefits for enterprises and Service Providers, most notably better service level agreements (SLAs) per location regardless of location.
Key standards and implementation agreements supporting CE 2.0 were completed by the MEF in January. The Metro Ethernet Forum is also planning to offer CE 2.0 certifications.
