The MEF Certification Program for Carrier Ethernet services which are certified to conform to the MEF specification ensures the services conform to the five attributes specified. In view of the Carrier Ethernet standardisation, these Carrier Ethernet services can be delivered to the customer without the need for the customer to change the network or LAN equipment. The standardised include: Ethernet Private Line (E-Line), Ethernet Private LAN (E-LAN services), Ethernet Virtual Private Line and Ethernet Virtual Private LAN services. Standardised services: One key advantage of Carrier Ethernet is that the services are standardised enabling easy implementation and interfacing wherever the user is located.In order to understand the benefits of using Carrier Ethernet, it is necessary to look at the five key attributes mentioned int he MEF definition. It is these aspects rather than the technical definitions of the bearer technology that differentiate Carrier Ethernet from the basic technical Ethernet standard. These affect the way it can be used and aspects like reliability, latency, and the like are particularly important. Instead they are far more concerned with the levels of performance that are achieved. Users are not particularly concerned about the technical method that is used to carry the data. The reason is that the Ethernet standard works very well and this is the reason why it has been adopted, but carriers or operators and their users need more than just a technical standard that defines the technical aspects.įor Carrier Ethernet, it is necessary to define other operational aspects as well. The question may be asked about the reason for having Carrier Ethernet when there is a perfectly good technical standard to define the technical aspects of the Ethernet interface used. It is useful to have the Carrier Ethernet definition because it enables users of Ethernet to understand exactly what CE is when compared to basic Ethernet. These attributes are standardized services, scalability, reliability, management and quality of service. The MEF has defined Carrier Ethernet as a ubiquitous, standardized, carrier-class service and network with five attributes that distinguish it from familiar LAN-based Ethernet. The Metro Ethernet Forum has set out a definition of what carrier Ethernet is. This industry body has over 200 members of companies associated associated with the Carrier and Metro Ethernet industries as service providers, manufacturers, developers and the like. In order to promote and coordinate the technology and the relevant standards for carrier and Metro Ethernet, the Metro Ethernet Forum, MEF was set up in 2001. With business local area network requirements increasing and requiring different business LANs of different sites to be connected, as well as other areas like mobile backhaul needing an effective communications protocol, the concept of first Metro Ethernet and then Carrier Ethernet arose. As a result, it has become the standard of choice for most computer networking applications. It is also widely used for direct links between various computer nodes.Įthernet provides both speed and low level of cost because of its wide deployment and in addition to this, the Ethernet protocol is straightforward and easy to use, and its use is easily scaleable. Carrier Ethernet developmentĮthernet has been available for many years and has become the protocol of preference for local area networks for business and home. Traditionally the terms Metro Ethernet and Carrier Ethernet have been used interchangeably, but now Carrier Ethernet is normally the term that is used to signify a system that has additional facilities, and greater reliability, although in some areas there still might be distinctions between two implementations. Typically Carrier Ethernet is used to provide point to point data links, links between local area networks, backhaul for mobile communications base stations and many other applications. What is Carrier Ethernet - the basics Carrier Ethernet basics - an Ethernet system that is used by carriers or service providers for high speed links for point to point links, LANs, mobile backhaul, etc.Įthernet introduction Standards Ethernet data frame structure 100Mbps Fast Ethernet Gigabit Ethernet, 1GE 10 Gigabit Ethernet, 10GE Single Pair Ethernet, SPE Ethernet cables How to buy Ethernet cables Routers, hubs, switches - the differences Ethernet switch How to buy best Ethernet switch Ethernet industrial switch Power over Ethernet, PoE Ethernet splitter Carrier Ethernet Ethernet Products Shopping PageĬarrier Ethernet is a term that is used to describe Ethernet communications links that enable telecommunications network providers to provide Ethernet services to utilise Ethernet technology in their networks.
