MEF Carrier Ethernet 2.0


On February 23 in Los Angeles, Bob Metcalfe, the inventor of Ethernet and advisory director of the Metro Ethernet Forum (MEF), announced the launch of Carrier Ethernet 2.0 (CE 2.0). What exactly is CE 2.0?

CE 1.0 introduced standardized Ethernet services over a single provider’s network. CE 2.0 goes beyond that by introducing three powerful and standardized features – multiple classes of service (Multi-CoS), interconnect and manageability – over eight services: two each for E-Line, E-LAN, E-Tree, and E-Access. Furthermore, CE 2.0 carries newly standardized and powerful Multi-CoS service features with performance objectives, interconnect and manageability.

Fault management, for example, will be standardized at a level that was not previously possible for services delivered across multiple providers. This enables the sectionalization of faults down to individual virtual connections.

CE 2.0 will more efficiently support cloud services and address the future needs of large enterprises, small and medium-sized businesses, retail and wholesale service providers, and mobile operators.

Service efficiency and application differentiation translate directly into cost savings and quality delivery of high performance applications. For the first time, enterprises will be able to validate that the services being offered closely match the performance and QoS requirements of each application and collectively meets its needs. This will facilitate network planning, and understanding how new applications will function.

For small and medium-sized businesses, Multi-CoS allows Internet and hosted services to be accessed via a single Carrier Ethernet connection, but with improved SLAs. For mobile operators and transport providers, Multi-CoS will ensure greater Quality of Service, lower operating costs and increased revenue opportunities.

In addition, CE 2.0 lays the foundation for additional efficiencies and cost-savings for mobile operators by implementing backhaul-specific performance objectives, packet and network-based synchronization, resiliency performance, and service OAM fault management. It is anticipated that this will have a significant impact on 4G/LTE build-outs.

As a member of the MEF, RAD Data Communications has taken an active role in the formulation and propagation of MEF standards. The company’s new ETX-5300A Ethernet Service Aggregation Platform is one of the first devices in the market to conform to emerging 2.0 specifications.
