Data communications are known for the variety of their communication protocols and interfaces. Throughout the decades of their development, various interfaces have been created for data transmission, while all these interfaces are dependent on communication protocols and devices connected to them. With each such new interface the complexity of the network has increased, while its maintenance has been extremely demanding. When we need to provide a service, whether to the customer or internally within the organisation, each new type of a physical interface makes service provisioning more complicated and expensive. Ideally, we would have a single physical interface able to provide various services.
This requirement is fulfilled by Carrier Ethernet, with a single physical interface providing different services under the applicable SLA. We can transmit Ethernet frames through the most media currently available. E1 links can be employed for data transfer, as well as metallic links, SDHs or microwave connections.
Through Carrier Ethernet we can create a single interface for all services within our heterogenous network. Each service can use its own SLA regardless of the transmission technology being employed. All devices connected will work with a single interface – the Ethernet. Furthermore, Ethernet interface is less expensive than SDH interface.
