Today there are a number of access technologies also referred to as “first-mile” or “last-mile” technologies that are used to deliver MEF-compliant Carrier Ethernet services.

Enterprise set of customers are looking up to Service Providers to provide them with uninterrupted Ethernet access and deliver a ubiquitous Carrier Ethernet service can and should deploy a number of available access technologies to ensure they can reach all of their end customers’ locations.

The Metro Ethernet Forum has defined Carrier Ethernet as a ubiquitous, standardized, carrier-class service and network with five attributes that distinguish it from familiar LAN-based Ethernet. These attributes are standardized services, scalability, reliability, management and quality of service.

The basic Carrier Ethernet service building blocks are E-Line (Ethernet Private Line and Ethernet Virtual Private Line), E-LAN and E-Tree.
Point-to-Point Ethernet Virtual Connections
Carrier Ethernet Network
Ethernet Virtual Private Line (EVPL)

A large number of corporate IT managers are exploring ways to add network capacity while maintaining or reducing their recurring operating expenses. And as a result increasingly, enterprise customers are moving away from traditional TDM, Frame Relay or ATM circuits and increasingly turning towards the Carrier Ethernet way with Ethernet Services to address these apparently ever changing needs.

Service providers have responded with rich offerings that combine hereto fore unmatched scalability and flexible bandwidth options with reliability and quality of service previously only available with old fashioned communications focused telecom circuits.

Industry forums and standards bodies like the MEF, IEEE, ITU-T and IETF have developed the necessary extensions to the original Ethernet protocol, making it suitable for service provider applications. For its part, the MEF has documented a  number of technical requirements for building and managing feature-rich business-class Ethernet services for the operators.

With enterprise customers always looking up to uninterrupted connectivity access, that can support them with next generation access, carrier grade Ethernet is turning out to be the answer for their issues and challenges that relate to communications infrastructure and moving forward this is likely to get further deployed within the enterprise segment.
