How Does Carrier Ethernet Work?
As its name suggests, Carrier Ethernet is monitored and deployed by a carrier, usually an internet provider. Traditional Ethernet connections can perform poorly under heavy access; Carrier Ethernet, on the other hand, can be divided across copper cables, Wi-Fi, satellite internet and Ethernet cables as needed to deliver fast, versatile network access. This gives businesses more options in structuring their operations and more integration across multiple locations and devices.
Why do businesses use carrier Ethernet?
Businesses use Carrier Ethernet to overcome the slow data transmission associated with traditional Ethernet when too many computers or servers attempt to connect to the host.

What is carrier Ethernet demarcation?from en.wikipedia.org
Carrier Ethernet demarcation devices ( EDD) are required to support services, such as Ethernet Private Line (EPL), Ethernet Virtual Private Line (EVPL or E-LAN), and Ethernet Virtual Private Tree (E-Tree), as specified by the MEF. Such support needs to include service level agreement (SLA) management capabilities, with consistent performance over fiber, DSL, bonded PDH, and SDH/SONET access lines. As a result, must-have Carrier Ethernet demarcation features include sophisticated traffic management and hierarchical quality of service (QoS) mechanisms, standard end-to-end operations, administration and maintenance (OAM) and performance monitoring, extensive fault management and diagnostics, and SDH/SONET-like resiliency to reduce service provider operating costs and capital expenses.

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 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.
Why is Ethernet so popular?
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. In part, it is also due to ease of deployment, using its ability to self-configure based on the key concepts of "learning bridge" ( flooding, and associating learned destination addresses with bridge ports) and " spanning tree protocol " (the protocol used for avoiding bridging loops).

Why are competing protocols and cabling created?
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. Examples include FireWire and Light Peak. One motive to create competing standards has been to drive down the price of comparable-speed Ethernet devices. Once this purpose is achieved, competing standards tend to disappear or be confined to very specialized niches.
