perfsonar development work

[Stephan Kraft <>]

Hi Andreas,

i added some comments on the document (attached). Main point for HADES 
and BWCTL will be, that it is not foreseen to put the "business logic" 
for finding related MPs into the HADES MA or the BWCTL MP. The point is 
to find a way to correlate the traceroute information with the topology 
service (cNIS), together with the lookup service.

A proper way may be a "Traceroute MA" containing the information about 
traceroute of N=n(n-1) measurement paths (50 boxes representing 2450 
measurements, _not_ containing additional measurements like IPv6, ToS 
etc.). This Traceroute MA can be requested by cNIS, LS etc.. Starting 
and ending point will be the measurement box (HADES, BWCTL other ...), 
the work will be to match the paths between the boxes and the paths 
between the corresponding routers. This should not be done by HADES MA 
(not only because it then just works for the HADES MA).

Best

Stephan
