Abstract:
Troubleshooting TCP packet loss is a crucial problem for many network applications. TCP packets could be lost in different network segments for various reasons. Understanding the responsible parties for TCP loss is an important step for network operators to diagnose related problem. However, TCP is designed for end-to-end control. It is difficult for any third party to detect whether and where (even coarsely) TCP packet loss has occurred. We design TCPBisector, a lightweight efficient diagnosis tool to manifest responsible parties for TCP packet loss. TCPBisector divides the responsibility between “My” and “Other” parties or networks (denoted as Netm and Neto) conceptually delimited by a passive network measurement point (denoted as MP), and quantifies the responsibility by using TCP packet loss ratios on the corresponding networks. The evaluation shows that the TCPBisector can accurately estimate TCP packet loss ratios with estimation error rate 3.5-6.9%.
