Abstract:
1. A method comprising: monitoring, by a layer-2 network switching system, a performance of a plurality of layer-2 network paths connecting a layer-2 network switch device to another layer-2 network switch device, the performance of the plurality of layer-2 network paths including a latency parameter and a congestion parameter for each of the plurality of layer-2 network paths; and selecting, by the layer-2 network switching system, an optimal one of the plurality of layer-2 network paths over which to forward data traffic based on a comparison of sums of parameter values for the plurality of layer-2 network paths, the sums including a calculated sum total of a financial cost parameter value, a latency parameter value for the monitored latency parameter, and a congestion parameter value for the monitored congestion parameter for each of the plurality of layer-2 network paths.
