perfsonar development work

[Andreas Hanemann <>]

Hi Stephan,

Based on your proposal the business logic in the visualisation could 
then look as follows.

- Traceroute output should be transformed to router locations (for my 
own convenience ignoring the proposal from Jeff at the moment).
- The router locations are checked against the LS whether there are 
HADES measurement locations (I am assuming that the registration of 
HADES MA to the LS then lists all the measurement locations).
- For all location pairs that are derived from the locations, the 
traceroute MP is asked for actual routes.
- Finally, the HADES MA is asked for actual measurement data for 
interesting location pairs.

I will work on the document to integrate this.

Best regards
Andreas
