网络运营商在对等点将其骨干网络连接在一起。众所周知，对等点是骨干网络中最拥塞的部分。网络运营商没有动力去很好地配置它们，也没有什么工具来决定如何最好地通过它们路由流量。在本文中，我们提出了对等网络如何实现无拥塞，只要我们知道它们之间的总流量。特别是，我们建议使用 valiant 负载均衡（VLB），之前已经针对各个骨干网络进行了研究。在我们的方法中，骨干网络不需要在内部使用 VLB - 它们只需通过对等链路对流量进行负载平衡。我们的分析显示了应该如何进行负载平衡，并且我们得出的结论是，在实现无拥塞网络方面，没有其他方法比 VLB 更有效。
Network operators connect their backbone networks together at peering points. It is well known that the peering points are the most congested parts of the backbone network. Network operators have little incentive to provision them well, and have few tools to decide how best to route traffic over them. In this paper we propose how peering networks can be congestion free, so long as we know the total amount of traffic between them. In particular, we propose the use of valiant load-balancing (VLB), which has been previously studied for individual backbone networks. In our approach, the backbone networks do not need to use VLB internally - they simply load-balance traffic over their peering links. Our analysis shows how the load-balancing should be done, and we conclude that no other method is more efficient than VLB in achieving a congestion-free network.
