摘要

主动监控TCP连接有助于在给定设置中研究此类连接的稳定性。随着旨在为最后一英里问题提供解决方案的接入技术的出现,需要有一种方法使ISP能够研究此类设备上的TCP连接。TCP本身被设计为稳定的,并且已被证明在许多访问技术中是稳定的。但在许多情况下,从客户的角度来看,这种联系不够稳定。我们一直致力于开发一种TCP连接监控方法,使ISP能够研究连接丢失的速率。我们开发了一个连接监控工具(common),除了检测连接中断之外,还可以测量往返时间和吞吐量。为了研究可能的连接中断的原因,还跟踪了到终点的路径。我们在有线局域网、电缆调制解调器和宽带无线技术上测试了该工具。

Broadband wireless local loop evaluation via an active TCP connection monitoring methodology
Active monitoring of TCP connections aids in the study of the stability of such connections over a given setup. With the advent of access technologies aiming to provide solutions to the last mile problem, there needs to be a method by which an ISP can study TCP connections over such equipment. TCP in itself has been designed to be stable and has been proven to be stable over many access technologies. But in many cases, the connections are not stable enough from a customer's perspective. Our effort has been to develop a TCP connection monitoring methodology that the ISP can study the rate at which connections are lost. We develop a connection monitoring tool (ConMon) that measures round trip time and throughput apart from detecting connections drops. The path to the end point is also traced in order to study reasons for possible connection drops. We test this tool over wired LAN, cable modem and broadband wireless technologies.
