网络间更加对等的趋势通常与互联网扁平化的趋势混为一谈，即互联网路径上中介组织数量的减少。事实上，直接对等互连绕过了第三层传输提供商，使互联网更加平坦。本文研究了一种分离这两种趋势的新兴现象：我们首次系统地研究了远程对等，即远程网络通过第二层提供商对等的互连。我们的测量结果显示，在全球范围内，ixp（互联网交换点）上存在着显著的远程对等。基于地面真实流量，我们还表明远程对等具有卸载过境流量的巨大潜力。在总结经验结果的基础上，我们分析得出了远程对等网络相对于传输对等网络和直接对等网络的经济可行性条件。由于远程对等服务是在第2层提供的，因此我们的研究结果挑战了在建模互联网经济结构时对第3层拓扑的传统依赖。我们还讨论了远程对等对互联网研究的可靠性、安全性、可问责性和其他方面的广泛影响。
The trend toward more peering between networks is commonly conflated with the trend of Internet flattening, i.e., reduction in the number of intermediary organizations on Internet paths. Indeed, direct peering interconnections bypass layer-3 transit providers and make the Internet flatter. This paper studies an emerging phenomenon that separates the two trends: we present the first systematic study of remote peering, an interconnection where remote networks peer via a layer-2 provider. Our measurements reveal significant presence of remote peering at IXPs (Internet eXchange Points) worldwide. Based on ground truth traffic, we also show that remote peering has a substantial potential to offload transit traffic. Generalizing the empirical results, we analytically derive conditions for economic viability of remote peering versus transit and direct peering. Because remote-peering services are provided on layer 2, our results challenge the traditional reliance on layer-3 topologies in modeling the Internet economic structure. We also discuss broader implications of remote peering for reliability, security, accountability, and other aspects of Internet research.
