The bandwidth module determines a percentage of bandwidth allocated to one of a plurality of protocols at an enhanced transmission selection (ETS) enabled network switch. The resource module determines a number of resources allocated for a plurality of virtual machines, the number of resources classified between the plurality of protocols. The variance module compares the percentage of bandwidth and the number of resources to determine a variance. The adjustment module adjusts the percentage of bandwidth allocated to the one of the plurality of protocols based on the variance. ## Claims ### Claim 1 A method, comprising: determining a percentage of bandwidth allocated to one of a plurality of protocols at an enhanced transmission selection (ETS) enabled switch;
