System and method for estimation of round trip times within a TCP based data network
Abstract:
A system and method for estimation of round trip times (RTTs) within a TCP based data network is described. The system provides for a passive monitoring of the network round-trip latency by simply observing existing TCP connections in operation. In this way, it is possible to measure RTT out to a remote site without having to send any traffic to that site with the result that there is no impact on the network, and it is possible to estimate what production traffic is experiencing.
Abstract(Chinese):

描述了一种用于估计基于TCP的数据网络内的往返时间（RTT）的系统和方法。 该系统通过简单地观察操作中的现有TCP连接来提供网络往返延迟的被动监控。 以这种方式，可以将RTT测量到远程站点，而不必向该站点发送任何流量，从而对网络没有影响，并且可以估计生产流量正在经历的情况。
