Carrier Ethernet demarcation is a key element in Carrier Ethernet services and transport networks for business, wholesale and mobile backhaul applications, as it enables service providers to extend their control over the entire service path, starting from the hand off points.
This happens in Ethernet links because of the way nodes "back off" from the link and attempt to re-access it. In the Ethernet protocol, when a communication collision happens (when two users of the medium try to send at the same time), each user waits for a random period of time before re-accessing the link.
The challenge of carrier Ethernet is to add carrier-grade functionality to Ethernet equipment without losing the cost-effectiveness and simplicity that makes it attractive in the first place. To meet this challenge, common connection-oriented Ethernet solutions have chosen to rid themselves of the complex parts of packet transport to achieve ...
A metropolitan-area Ethernet, Ethernet MAN, carrier Ethernet [1] or metro Ethernet network is a metropolitan area network (MAN) that is based on Ethernet standards. It is commonly used to connect subscribers to a larger service network or for internet access .

The increased overhead of extra MPLS and Ethernet headers means that the support for frames up to 1600 bytes is required in Carrier Ethernet networks. [ 19 ] Jumbo frames for PPPoE is defined in RFC 4638, with the purpose of removing the old 1492-byte limit (originally defined because PPP needs 8 more bytes of overhead), so that normal 1500 ...
In telecommunications, a network interface device (NID; also known by several other names) is a device that serves as the demarcation point between the carrier's local loop and the customer's premises wiring. Outdoor telephone NIDs also provide the subscriber with access to the station wiring and serve as a convenient test point for ...
A standalone Carrier Routing System is deployed with a Line card chassis (LCC). The three main functional units of this LCC are the Line cards, Switching fabric and Route processor. The Line card consists of the physical interface card and a modular services card. The physical connectivity could be using fiber-optic cables or using Twisted pair ...
