Purpose
• Carrier Ethernet Services Overview
– This presentation defines the MEF Ethernet
Services that represent the principal attribute of a
Carrier Ethernet Network
– This presentation is intended to give a simple
overview as a grounding for all other MEF
documents

MEF Carrier Ethernet Terminology
• The User Network Interface (UNI)
– The UNI is the physical interface or port that is the
demarcation between the customer and the service
provider/Cable Operator/Carrier/MSO
– The UNI is always provided by the Service Provider
– The UNI in a Carrier Ethernet Network is a physical
Ethernet Interface at operating speeds 10Mbs, 100Mbps,
1Gbps or 10Gbps

MEF Carrier Ethernet Terminology
• Ethernet Virtual Connection (EVC)
– Connects two or more subscriber sites (UNI’s)
– An association of two or more UNIs
– Prevents data transfer between sites that are not part
of the same EVC
– Three types of EVC
• Point-to-Point
• Multipoint-to-Multipoint

EVCs and Services
In a Carrier Ethernet network, data is transported
across Point-to-Point and Multipoint-to-Multipoint
EVCs according to the attributes and definitions of
the E-Line and E-LAN services

Services Using E-Line Service Type
• Ethernet Virtual Private Line (EVPL)
– Replaces Frame Relay or ATM services
– Supports Service Multiplexed UNI
(i.e. multiple EVCs per UNI)
– Allows single physical connection (UNI) to customer
premise equipment for multiple virtual connections

Circuit Emulation Services over Carrier Ethernet
• Enables TDM Services to be transported
across Carrier Ethernet network, re-
creating the TDM circuit at the far end
– Runs on a standard Ethernet Line Service (E-Line)

Related MEF Services Specifications
MEF 6 Metro Ethernet Services Definitions Phase I
Purpose Defines the Ethernet Services (EPL, EVPL, E-Line, ELAN, etc)
MEF 10.1 Ethernet Services Attributes Phase 2
Defines the service attributes and parameters required to offer the services
Purpose
defined in MEF 6. Updated from Original MEF 10 in October 2006
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
Audience
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.
