Up: Sting: a TCP-based Network
Previous: Experiences
In this paper, we have described techniques for measuring packet loss
using TCP. Using these methods the sting tool can separately derive
measures for packet loss along the forward and reverse paths to a host,
and can be used to probe any TCP-based server. In the future we plan
to develop TCP-based techniques for estimating
bandwidth [LB99], and round-trip time, and for deriving queue
length distributions.
