Abstract

A farm of network processors can be power controlled or clock frequency controlled according to the load they are exposed to. Frequency control has a linear impact on power consumption whereas power amplitude control even has a square impact on power consumption. Network processors can be driven at a frequency or power amplitude level demanded by the traffic. This idea can be extended to load balancing over a number of network processors. The network processors are switched on according to network traffic demand. Such a system, especially combined with load balancing, has extremely desirable properties such as reliability, plug and play, power consumption. The system can also be combined with traffic estimation in order to determine when to increase/decrease frequency or power. This technique also has the property of smoothing traffic (avoiding burst). 1
