It makes use of a number of basic transport protocols, including SDH and increasingly Ethernet. This is achieved by connecting customer premises equipment CPE to the network with provider-owned demarcation devices that are deployed at customer locations, thereby enabling a clear separation between the user and provider networks. 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.

It makes use of a number of basic transport protocols, including SDH and increasingly Ethernet. 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. Parts of this article those related to Carrier Ethernet 2. Unsourced material may be challenged and removed.
From the original ep-4bea9ii coaxial cable format ” thicknet ” it has extended its scope to nearly all copper, optical fiber and wireless physical media. Ethernet family of local area network technologies. Analogous definitions for wireless networks are defined in IEEE Accordingly, carriers must expand their services conservatively and pay close attention to Quality of Service QoS. The principal concept was to bring the simplicity and cost model of Ethernet to the wide area network.
These standards allow for Ethernet networks of planetary scale. Once this purpose is achieved, competing standards tend to disappear or be confined to very specialized niches.
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.
Carrier Ethernet – Wikipedia
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 particular, mechanisms to isolate one customer’s traffic from another, to measure performance of a customer service instance, and to rapidly detect and repair failures in large networks.
This is achieved by connecting customer premises ep-4bae9i CPE to the network with provider-owned demarcation devices that are deployed at lna locations, thereby enabling a clear separation between the user and provider networks. It has become dominant in enterprise networks. Services that try to expand too fast lose money while those that wait too long lose customers.
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. This page was last edited on 9 Septemberat They are also constrained as services cannot be migrated from local to wide area services too fast lest they exceed the total provisioning ep–4bea9i and result in unacceptable quality.
Bit rates have continued ep-4bsa9i increase, traditionally growing tenfold each time a new rate is defined. Please help improve it or discuss these issues on the talk page.
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. Retrieved from ” https: Moreover, customers are familiar with the capabilities of Ethernet networks, and would like to extend these capabilities to multi-site lwn. Ethernet has a long history.

Examples include FireWire and Light Peak. For example, time domain capabilities are being added to IEEE Retrieved 22 September Thus, the use of Ethernet in a metro network allows service providers to take advantage of volumes that a much larger enterprise segment commands.
