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 (UNIs)
• 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

Carrier Ethernet Two Service Types Using EVCs
E-Line Service type

• E-Line Service used to create
• Ethernet Private Lines
• Virtual Private Lines
• Ethernet Internet Access
• E-LAN Service used to create
• Multipoint L2 VPNs
• Transparent LAN Service
• Foundation for IPTV and Multicast networks etc.

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 Private Line (EPL)
• Replaces a TDM Private line
• Dedicated UNIs for Point-to-Point connections
• Single Ethernet Virtual Connection (EVC) per UNI

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)

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.
