The services are categorized as an E-Line service type, with an expectation of low frame delayframe delay variation and frame loss ratio. Ethernet family of local area network technologies.

Despite the advantages described above, Ethernet has traditionally had a number of limitations in the WAN application. Please update this article to reflect recent events or newly available information.

Historically, competing protocols and cabling have been created in order to access higher speed devices than contemporary Ethernet-connected devices handled at an affordable price. Retrieved August 6, In part, it is also due to ease of deployment, using its ability to self-configure based on the key concepts of “learning bridge” floodingand associating learned destination addresses with bridge ports and ” spanning tree protocol ” the protocol used for avoiding bridging loops.

This page was last edited on 9 Septemberat One motive to create competing standards has been to drive down the price of comparable-speed Ethernet devices. All these services provide standard definitions of such characteristics as bandwidth, resilience and service multiplexing, allowing customers to compare service offerings and facilitating service level agreements SLAs.


Ethernet’s ubiquitous presence in the LANs worldwide drives down the cost of Ethernet as a technology.

The MEF was formed in in order to develop ubiquitous business services for Enterprise users principally accessed over optical metropolitan networks ep-4ea9i order to connect their Enterprise LANs. February Learn how and when to remove this template ep-4bea9k. Carrier Ethernet is a marketing term for extensions to Ethernet to enable telecommunications network providers to provide Ethernet services to customers and to utilize Ethernet technology in their networks.

Archived from the original on To create a market in Ethernet services, it is necessary to clarify and standardise the services to be provided. Archived from the original on 23 September Moreover, Ethernet has lacked some of the dependability features necessary in this application in particular, mechanisms to isolate one customer’s traffic from another, to fp-4bea9i performance of a customer service instance, and to rapidly detect and repair failures in large networks.

Carrier Ethernet – Wikipedia

Carrier-Ethernet Transport CET usually involves an evolution of conventional Ethernet and comprises multiple technology components.

The industry ep-4bea9u made a concerted effort to resolve the limitations of Ethernet in the WAN described above, so as to allow the use of “native” Ethernet technologies by network providers.

Please help improve it or discuss these issues on the talk page.

For example, time domain capabilities are being added to IEEE Customer LAN networks are increasingly connected to wide-area telecommunications networks over Ethernet interfaces or to devices ep-b4ea9i bridge digital subscriber line DSL or wireless to these.

Moreover, customers are familiar with the capabilities of Ethernet networks, and would like to extend these capabilities to multi-site networks. Ethernet is a fairly simple protocol which has scaled to hundreds of thousands of times faster speeds and consistently been able to adapt to meet the needs and demands of new markets. Provider Backbone Bridging-Traffic Engineering is allowing such an Ethernet to be controlled by an external control or management application for example, a network management application or a transport control plane such as GMPLS IETF RFCso as to allow the full range of traffic engineering policies and strategies to a network provider.

Ethernet has a long history. Please help improve it to make it understandable to non-expertswithout removing the technical details. November Learn how and when to remove this template message. The principal concept was to bring the simplicity and cost model of Ethernet to the wide area network.
