Data communications are renowned for the variety of communication protocols and interfaces. In the decades of its development there were created different interfaces for transmitting data and all of these interfaces are dependent on communication protocols and devices connected to them. For each new interface the complexity of the network increased and its maintenance was and is extremely demanding. If we need to transmit the service, whether to the customer or internally within the organization, each additional physical interface makes transmitting service more difficult and expensive. The ideal solution would be to have one physical interface, which can transmit various services.
Carrier Ethernet meets the requirement; one physical interface is transmitting different service with require SLA. It is possible to transmit Ethernet frames through the most available media. With transport can be used several E1 link, some copper pair or even several SDH interfaces STM-1, STM-4 capable transmit 1GB Ethernet. Radios have on their output Ethernet with EDD functionality.
Carrier Ethernet allows us to create a wrap around our heterogeneous network with united interface for all of the transmitting service – Ethernet. Every service can have their own SLA without any heed on transmission technology. All connected devices will have one interface - Ethernet. For example, Ethernet router connection is significantly cheaper than SDH.
