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

Carrier Ethernet Network

UNIUNI

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

CE: Customer Equipment, UNI: User Network Interface. MEF certified Carrier Ethernet products

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

6

Carrier Ethernet: Two Service Types Using EVCs

• 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)

Related MEF Services Specifications

Purpose Defines the Ethernet Services (EPL, EVPL, E-Line, ELAN, etc)

MEF 6MEF 6

PurposeDefines 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.
