21 21 Related MEF Services Specifications PurposeDefines the Ethernet Services (EPL, EVPL, E-Line, ELAN, and E-Tree) MEF 6.1 Purpose Defines the service attributes and parameters required to offer the services defined in MEF 6. Updated from Original MEF 10 in October 2006 Audience Appropriate for equipment vendors, service providers, and business customers, since it provides the fundamentals required to build devices and services that deliver Carrier Ethernet. For Enterprise users it gives the background to Service Level Specifications for Carrier Ethernet Services being offered by their Service Providers and helps to plan Ethernet Services as part of their overall network.
