英文摘要: Abstract(#br)This paper proposes and evaluates a novel, edge-based approach, which we call the k -set Traffic Engineering (TE) method, to perform traffic engineering in OSPF networks by partitioning traffic into uneven k -traffic sets. The traffic partitioning and splitting takes place only at network edges, leaving the core simple. We theoretically prove that if k is large enough, the k -set TE method achieves the general optimal traffic engineering where full-mesh overlaying and arbitrary traffic splitting, such as in MPLS, have to be used. We give an upper bound of the smallest k that achieves such a general optimum. In addition, we provide a constant worst case performance bound if k is smaller than the optimal k . Finding the optimal traffic splitting and routing for a given k is...
