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. Views Read Edit View history. Please help improve it or discuss these issues on the talk page. One motive to create competing standards has been to drive down the price of comparable-speed Ethernet devices. The OIF and the Ethernet Alliance have also been working cooperatively with their members to enable future enhancements to Ethernet for the WAN while looking to the future speed of Ethernet technologies and services.

This page was last edited on 9 Septemberat Services that try to expand too fast lose money while those that wait too long lose customers.
The principal concept was to bring the simplicity and cost model of Ethernet to the wide area network. Retrieved 22 September Learn how and when to remove these template messages. Customer LAN networks are increasingly connected to wide-area telecommunications networks over Ethernet interfaces or to devices that bridge digital subscriber line DSL or wireless to these.
Archived from the original on Ethernet’s dominance is partly attributed to the simple advantages for the industry of adopting a single standard to drive up volumes and drive down prices.
Historically, competing protocols and cabling have been created in order to access higher speed devices than contemporary Ethernet-connected devices handled at an affordable llan. From Wikipedia, the free encyclopedia.
Archived from the original on 23 September The services are categorized as an E-Line service type, with an expectation of low frame delayframe delay variation and frame loss ratio. This article has multiple issues.
The industry has made a concerted effort to resolve the limitations e-p4bea9i Ethernet in the WAN described above, so as to allow the use of “native” Ethernet technologies by network providers. Ethernet family of local area network technologies. Bit rates have continued to increase, traditionally growing tenfold each time a new rate is ep-4beea9i.
Provider Backbone Bridging-Traffic Engineering rp-4bea9i 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.
Once this purpose is achieved, competing standards tend to disappear or be confined to very specialized niches. 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 article needs additional citations for verification. Ethernet’s ubiquitous presence in the LANs worldwide drives down the cost of Ethernet as a technology. Two types of technology have been widely used, while a third Carrier-Ethernet transport is rapidly emerging as a viable and logical option for Carrier-Ethernet services. Please help improve this article by adding citations to reliable sources. This dominance has led to high production-volume components, which in turn have allowed extremely low cost per bit.
Moreover, Ethernet has lacked some of the dependability features necessary in this application in la, mechanisms to isolate one customer’s traffic from another, to measure performance of a customer service instance, and to laj detect and repair failures in large networks.

For example, time domain capabilities are being added to IEEE 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.
The success of Metro Ethernet Services caught the imagination of the world when the concept expanded to include worldwide services traversing national and global networks: Examples include FireWire and Light Peak.

This article may be too technical for most readers to understand. Analogous definitions for wireless networks are defined in IEEE From the original copper coaxial cable format ” thicknet ” it has extended its scope to nearly all copper, optical fiber and wireless physical media.
