Carrier Ethernet Defined

The MEF has defined Carrier Ethernet as A ubiquitous, standardized,carrier-class Service and Network defined by five attributes that distinguish it from familiar LAN based Ethernet

Carrier Ethernet is often referred to in Enterprise circles as Ethernet Business Services. The MEF is the industry’s defining body for Carrier Ethernet.

Carrier Ethernet Basics

Key Carrier Ethernet Terminology EVC: Ethernet Virtual Connection UNI: User Network Interface: the physical demarcation point

between the responsibility of the Service Provider and the responsibility of the Subscriber

Ethernet Private Line (EPL)

!Replaces a TDM Private line Port-based service with single service (EVC) across dedicated UNIs providing site-to-site connectivity Typically delivered over SDH (Ethernet over SDH) Most popular Ethernet service due to its simplicity

What is a service? MEF View

A service is the “connection with attributes” between 2 or more UNIs Point-to-point or multipoint-to-multipoint (everything else is a derivative)

Service Multiplexing allowed at UNI Example use: Internet access and corporate VPN via one UNI Every connection has an independent, service-specific SLA level

Private Cloud Services Example: Access to enterprise-grade business systems Secure, predictable, controlled, regulatory compliant

Additional BackgroundTerminology

CE 1.0 Original MEF Service Definition Certification of CE 1.0 is referred to as MEF 9 & 14 Certification Certification tests has many optional tests allowing a lot of variation in capabilities for those 9&14 certified

CE 2.0 Formally announced by the MEF in 2012 Builds on CE 1.0 Builds on specifications defined in CE 1.0 timeframe but not included in 9 & 14 tests Includes a suite of tests to verify compliance

Each topology is certified separately EP/EVP-LINE, EP/EVP-LAN, EP/EVP-TREE, and EP/EVP-ACCESS

Test suite has few optional components Test certification is more granular, allowing less variation among certified vendors.


CE 2.0 Basics


CE 2.0 BasicsEnhancements

Topologies are greatly enhanced from CE 1.0 !

E-LINE and EVP-LINE Increase in MTU, enhanced egress BWP, OAM, and enhanced L2CP

E-LAN and EVP-LAN Increase in MTU, enhanced egress BWP, OAM, and enhanced L2CP

E-TREE and EVP-TREE Now part of CE 2.0 certification Increase in MTU, enhanced egress BWP, OAM, and enhanced L2CP

ENNI and E-ACCESS services These topologies are all new


CE 2.0 BasicsUNI, BWP, and L2CP

UNI 2.0 is now required Enhancements over UNI 1.0 include MTU, OAM, and EVC Limits

Service classification at the UNI Essentially* unchanged from CE 1.0

L2CP Processing Greatly enhanced – MEF 6.1.1 is just L2CP

BWP Essentially* unchanged Still per UNI, EVC or Priority per EVC Now supported on OVC endpoints on ENNI

!!!!*There are some minor changes


ENNI and EP/EVP-ACCESS services added

CE 2.0 BasicsNew: Management and OAM

CE 2.0 includes “Service OAM” in most literature !

Link OAM (802.3ah) – Ethernet in the first (last) mile UNI-N to UNI-C In CE 2.0 !

CFM OAM (802.1ag) – CFM over EVC and OVC UNI-N to ENNI, UNI-N to UNI-N, and ENNI to ENNI CE 2.0 refers to this as “Service OAM” !

Performance Monitoring (Y.1731) - defined in MEF 35, 36 MEF standards exist, but are not included in CE 2.0

CE 2.0 BasicsMore on COS in CE 2.0

COS Definition (MEF 23.1) !

Defines COS models for EVC 3 COS model (High, Med, and Low)

High (EF for VoIP, MBH), MED and LOW (2 levels of AF) BE is also present (so technically 4 levels)

Coloring Specified support for both DEI, PCP, and (UNI-only) DSCP based coloring

Defines Performance Parameters and Tiers Valid Ranges for each tier of service are defined

Frame Delay Mean Frame Delay Inter-Frame Delay Variation Frame Delay Range Frame Loss Ratio


Metro Ethernet and Mobile Networks


Mobile Network Synchronization

Todays mobile networks need more than just frequency synchronization

Time of day for 1-way delay measurement Phase synchronization for reliable call handoff !

Delivering synchronization as a service offers transport providers an important revenue opportunity
