> Sting is unique because it can estimate "one-way" loss rates through
> careful manipulation and observation of TCP behavior. In addition, using
> TCP allows us to leverage the existing Internet infrastructure -- any TCP
> server can be used as a de facto measurement service -- and it avoids
> increasing problems with ICMP-based network measurement (blocking,
> spoofing, rate limiting, etc...).

> An initial no-frills source release is available at:
> http://www.cs.washington.edu/homes/savage/sting/
> It currently supports FreeBSD and (I think) Linux.
>
> A paper (from the 1999 USITS) describing the techniques and some initial
> measurements of loss asymmetry can be found at:
> http://www.cs.washington.edu/homes/savage/papers/Usits99.ps
> or

>
> We are currently developing additional tools that estimate one-way queuing
> delays and bandwidths using similar techniques.
