Detailed Description

Written by Osman Sarood This load balancing strategy is meant for temperature control.

It is mandotry to have access to frequency control to use it. It is a mixture of Refine and Comm LBs in addition to normalization being done according to frequencies. This load balancer can also cater for sensitivity to frequency that an applicaiton has to frequency.
