Designing a Predictable Internet Backbone with Valiant Load-Balancing
Abstract. Network operators would like their network to support current and future traffic matrices, even when links and routers fail. Not surprisingly, no backbone network can do this today: It is hard to accurately measure the current matrix, and harder still to predict future ones. Even if the matrices are known, how do we know a network will support them, particularly under failures? As a result, today’s networks are designed in a somewhat ad-hoc fashion, using rules-of-thumb and crude estimates of current and future traffic. Previously we proposed the use of Valiant Load-balancing (VLB) for backbone design. It can guarantee 100% throughput to any traffic matrix, even under link and router failures. Our initial work was limited to homogeneous backbones in which routers had the same capacity. In this paper we extend our results in two ways: First, we show that the same qualities of service (guaranteed support of any traffic matrix with or without failure) can be achieved in a real...
