Claim One:
1. A method of optimizing traffic in an internetwork, the method comprising: selecting a subset of flows in the internetwork for monitoring, wherein the subset of flows includes one of one flow, some flows, and all flows; measuring performance characteristics of the subset of flows in at least a portion of the internetwork, the performance characteristics including one or more of: a plurality of one or more round trip measurements for each of the subset of flows and a plurality of one or more one-way measurements for each of the subset of flows, the measuring performance characteristics including: encoding material within a first plurality of one or more flows, causing a second plurality of one or more flows to be generated, wherein the first plurality of one or more flows traverses a first path of the internetwork, and the second plurality of one or more flows traverses a second path of the internetwork, wherein at least a portion of the first path of the internetwork and at least a portion of the second path of the internetwork are equal, and measuring a subset of the second plurality of one or more flows; calculating at least one performance metric for the subset of flows in the at least a portion of the internetwork, the at least one performance metric at least partly determined from the measured performance characteristics; and in response to calculating the at least one performance metric, rearchitecting the internetwork to optimize one or more of the least one performance metric.
