A ubiquitous, standardized, carrier-class Service and Network defined by five attributes that distinguish it from familiar LAN-based Ethernet. Enterprise users more typically refer to Carrier Ethernet as Ethernet Business Services.

CE 2.0

CE 2.0 supercedes CE 1.0.  Since 2012 CE 2.0 - a new generation of Carrier Ethernet defined below - is having a significant impact on the market. CE 2.0 greatly expands from 3 services in CE 1.0 to

  • 8 services, 2 of each respectively in E-Line, E-LAN, E-Tree, and E-Access (defined in MEF Standards MEF 6.1, 22.1, 33)
  • The industry's first standardized Multi-CoS with application-oriented CoS Performance Objectives, new metrics (MEF 6.1, 10.2, 20, 23.1)
  • Interconnect through the integrated delivery of MEF Service Attributes (MEF 10.2, 26.1, 33) allows ubiquitous deployment spanning multiple providers
  • Manageability, (MEF 7.1, 16, 17, 30, 31) plus additional specifications

For Service Providers: CE 2.0 is set of MEF CE 2.0 Certified network elements that connect to transport Carrier Ethernet services for all users, locally & worldwide. Carrier Ethernet services are carried over physical Ethernet networks and other legacy transport technologies.

Further details are shown on the Carrier Ethernet Services page.


CE 1.0

The original Carrier Ethernet (now termed CE 1.0) delivers: standardized carrier-class services over one provider’s network.

Impact of Carrier Ethernet

  • Transformation of the delivery of business services from legacy TDM, SONET, and STM
  • In 2012, Bandwidth of Ethernet services exceeded all other legacy technologies, worldwide
  • Uninterrupted double digit service revenue growth since its inception (on track to exceed $100bn in 2017)
  • Enables key applications from Cloud Services to Mobile Backhaul over all technologies using traditional or SDN approaches
The evolution of Carrier Ethernet

What is Carrier Ethernet?

Bob Metcalfe, Inventor of Ethernet narrates the fascinating story of the Evolution of Ethernet to a Carrier Class Technology


"The approval of key MEF specifications and implementation agreements in 2012 marked the tipping point that a new generation of services and networks could be confidently deployed as a new industry standard. CE 2.0 provides a new dimension for industry growth and prosperity.” - Nan Chen, MEF President.

Standardized Services

  • E-Line, E-LAN provide transparent, private line, virtual private line, and LAN services
  • A ubiquitous service providing globally and locally via standardized equipment
  • Requires no changes to customer LAN equipment or networks and accommodates existing network connectivity such as, time-sensitive, TDM traffic and signaling
  • Ideally suited to converged voice, video, and data networks
  • Wide choice and granularity of bandwidth and quality of service options


  • The ability for millions to use a network service that is ideal for the widest variety of business, information, communications, and entertainment applications with voice, video, and data
  • Spans Access & Metro to National & Global Services over a wide variety of physical infrastructures implemented by a wide range of Service Providers
  • Scalability of bandwidth from 1Mbps to 10Gbps and beyond, in granular increments


  • The ability for the network to detect and recover from incidents without impacting users
  • Meeting the most demanding quality and availability requirements
  • Rapid recovery time when problems do occur, as low as 50ms

Quality of Service

  • Wide choice and granularity of bandwidth and quality of service options
  • Service Level Agreements (SLAs) that deliver end-to-end performance matching the requirements for voice, video, and data over converged business and residential networks
  • Provisioning via SLAs that provide end-to-end performance based on CIR, frame loss, delay, and delay variation characteristics

Service Management

  • The ability to monitor, diagnose, and centrally manage the network, using standards-based vendor independent implementations
  • Carrier-class OAM
  • Rapid service provisioning
