Conclusions
We have demonstrated several network analysis and
   a new method for monitoring ABw  and bottleneck
capacity in the range several Mbits to 1000 Mbits
ABwE is a non intrusive method which can be run in
     a continuous mode 24 hours a day 7 days a week
It can detect changes in the path capacity based on
heavy traffic and also discover dramatic changes in
routing. The usefulness of ABwE has been proven
several times since last summer
Unfortunately, ABwE still doesn’t exists as a publicly
used tool
