Summary:
For several years, many researchers have been working on reducing power consumption in telecommunication networks. All tasks undertaken in this area, called also "green energy" or "green communication", are very important because they provide a major contribution to the natural environment protection. Networks called "green networks" can be described as networks in which requested throughput, required delay, and the minimum required number of users are ensured, and simultaneously, power consumption remains at a minimal level. Moreover, green networks and their devices must be compatible with current native, energy intensive network environment. A switching node is an important element of a data transmission system such as a telecommunications network. Its task includes reliable and optimal (from the service quality point of view) data distribution to particular network areas as well as data exchange between autonomous networks. Each switching node is divided into a data plane and a control plane. In the data plane, each node contains a certain number of input and output interfaces through which end users in access networks or other switching nodes in backbone networks are attached. When an input interface receives a connection request, information about this event is sent to the control plane that is responsible for serving the received data. In my talk I will show that power consumption control plane can be reduced through several ways, for instance keeping a controller of the switching fabric as simple as possible or by using ternary content addressable memories (TACM). Regarding data plane, the reduction energy consumption can be done by adopting the structure of switching fabric to the intensity of traffic offered, providing lossless operation of the switching fabric at the same time.
