互联网服务提供商（ISP）使用复杂的对等策略，规定了与其他网络对等的各种规则。对等策略通常被认为是一种“黑艺术”，而不是科学，对等协商的结果可能取决于既不技术也不经济的因素。因此，ISP对他们应该对等的网络以及他们应该要求/提供的价格没有明确的想法，以确保稳定的对等链路。我们提出了一个定量框架的结算免费和付费对等链接，基于“价值”的对等链接，即，网络从这种联系中看到的好处。我们首先研究一种解决方案，其中集中式Oracle基于对每个网络的收入和成本的完美了解，为付费对等链路确定可证明稳定，最优和公平的价格。接下来，我们展示了在完美的知识下，集中式解决方案可以由对等网络单独实现。然后，我们研究了对等网络的对等价值的不准确估计的影响。最后，我们研究了基于价值的对等连接如何影响对等连接链路的密度，端到端路径的性质，以及全球互联网中各种网络类型的盈利能力。
Internet Service Providers (ISPs) use complex peering policies, stipulating various rules for peering with other networks. Peering strategy is often considered a “black art” rather than science, and the outcome of a peering negotiation can depend on factors that are neither technical nor economic. Consequently, ISPs do not have a clear idea of the networks they should peer with, and the price they should demand/offer to ensure a stable peering link. We propose a quantitative framework for settlement-free and paid-peering links, based on the “value” of a peering link, i.e., the benefit that networks see from that link. We first study a solution where a centralized oracle determines a provably stable, optimal and fair price for a paid-peering link, based on perfect knowledge of the revenues and costs of each network. We next show that with perfect knowledge, the centralized solution can be implemented individually by the peering networks. We then study the effects of inaccurate estimation of peering value by the peering networks. Finally, we examine how value-based peering affects the density of peering links, the nature of end-to-end paths, and the profitability of various network types in the global Internet.
