In the images presented we can clearly see that the traffic is very stable and is distributed in a very predictable as day and time, decreasing a bit Saturday and Sunday.

Measures are done once a day at 5:00 Chilean Local Time. By this data we got the following indicators: text/html 2010-11-08T18:42:59-03:00 Pablo Sepulveda http://www.niclabs.cl/terremoto/en/calculo_visibilidad?rev=1289252579&do=diff Measurement Procedure After obtaining all the AS Paths from all collectors to all networks we have to filter to get only the Chilean networks. This process is not as simple as doing a search on Chilean network list, it is also correct to announce subnetworks, i.e. a subset of the network that is owned.
