Internet connection is now as matter of course, whether it is a home, small business or large corporation. Internet throughput in comparison with its beginnings is enormous. From a user perspective the goal is reached when movies in high quality is pulling out faster than we can watch. High bandwidth network enables us to move most of the data in different data centres and clouds. Increasingly we use applications that are not on our local servers, but running directly from the private or public cloud. We are becoming dependent on a data connection; we can’t work without it.
The flexibility that cloud solutions deliver to us significantly increases the demands on data connections. Throughput is certainly no longer the only requirement on operators. We are interested in the availability and quality of data lines. Each application has different requirements. While some are dependent on the delay, others require minimal packet loss. The requirement on operators is offering different services on a single data connection. We require a service with different SLA, but only that one we can monitor and guarantee in the critical time.
Ethernet is an ideal medium for transmitting services with SLA. EDD (Ethernet Demarcation Device) can transmit multiple services on a single Ethernet port or split of the services on dedicated ports. For example, you can assign one port for transmissions requiring minimal delays and other port for services with minimal packet loss. On the network side the EDD may have different transmission technologies, from optics, xDSL to wireless links. Properties of EDD ensure quality of service and its measurement needs for the required SLA. Measurements and guaranteed service can be provided between two EDD, or against a defined point within the network.
