Internet connection is now commonplace, whether it is a home, a small business or a large corporation. Compared to its early times, Internet bandwidth is enormous. The goal has been reached from the user’s perspective, as we can stream HD movies faster than we can watch them. Thanks to high network bandwidth we can move most of the data to various data centers and clouds. Increasingly we are using applications running directly at the private or public cloud rather than our local servers. We are becoming dependent on data connection and we cannot work without it.
The flexibility delivered by cloud solutions results in rapidly increasing demand on data connections. Bandwidth is certainly no longer the only requirement that must be met by operators. We are interested in the availability and quality of data lines. Each application features different requirements. While some are delay sensitive, others require minimum packet loss. The requirement on operators is to offer different services through a single data connection. We require services with different SLAs, but only those that can be monitored and guaranteed within the critical time.
Ethernet represents an ideal medium to provide SLA-based services. Ethernet Demarcation Device (EDD) can deliver multiple services via a single Ethernet port, or split individual services to dedicated ports. For example, we can dedicate one port for transmission operations requiring minimum delay times, and another port for services requiring minimum packet loss. On the network side the EDD may employ various transmission technologies, from optics, to xDSL to wireless connections. EDD properties ensure service quality and its metering for SLA purposes. Service measurements and guaranteed SLA can be provided between two EDDs, or for a defined point within the network.
