Method of configuring interfaces between a plurality of communication nodes
View Patent ↗One embodiment includes monitoring, for each communication node, at least one factor of interest and a plurality of potential influencing factors associated with the factor of interest. The factor of interest characterizes an operating condition of the communication node, and the plurality of potential influencing factors each have a potential influence on the operating condition. For each factor of interest for each communication node, a predictor coefficient for one or more of the potential influencing factors associated with the factor of interest is determined. The predictor coefficient indicates a predicted level of influence the potential influencing factor has on the factor of interest. For each communication node, interfaces are configured between the communication node and other communication nodes based on the determined predictor coefficients.
