先前的文献已经对 ISP 之间的对等和传输互连的经济方面进行了广泛的研究。先前的研究主要集中于与在 ISP 之间建立对等和传输连接以建模互连策略相关的经济问题。另一方面，性能分析虽然可以直观地理解，但尚未根据经验进行量化并纳入此类模型中。为了填补这一空白，我们对对等互连和传输互连策略进行了基于大规模测量的性能比较。我们使用 JavaScript 在 900 个接入 ISP 的 510K 客户端和位于全球 33 个 IXP 的多宿主 CDN 服务器之间进行应用层延迟测量。总体而言，我们发现数据中 91% 的自治系统 (AS) 的对等路径优于传输路径。与超过 95% AS 的传输路径相比，对等路径的传播延迟更小。由于路径长度较短，对等路径在传播延迟方面优于传输路径。与超过 50% AS 的传输路径相比，对等路径的排队延迟也更小。
The economic aspects of peering and transit interconnections between ISPs have been extensively studied in prior literature. Prior research primarily focuses on the economic issues associated with establishing peering and transit connectivity among ISPs to model interconnection strategies. Performance analysis, on the other hand, while understood intuitively, has not been empirically quantified and incorporated in such models. To fill this gap, we conduct a large scale measurement based performance comparison of peering and transit interconnection strategies. We use JavaScript to conduct application layer latency measurements between 510K clients in 900 access ISPs and multi-homed CDN servers located at 33 IXPs around the world. Overall, we find that peering paths outperformed transit paths for 91% Autonomous Systems (ASes) in our data. Peering paths have smaller propagation delays as compared to transit paths for more than 95% ASes. Peering paths outperform transit paths in terms of propagation delay due to shorter path lengths. Peering paths also have smaller queueing delays as compared to transit paths for more than 50% ASes.
