Create 291 days ago | parent | on: UC Berkeley profs lambast new “black box” network ... Transparent monitoring for your protection In keeping with this spirit, here is a reminder of how we monitor (your) CERN activities. We monitor all network Traffic coming into and going out of CERN. Our new analysis infrastructure will be able to cope with the automatic live analysis of about one terabyte of data every day. All this data is stored for one year. http://cds.cern.ch/journal/CERNBulletin/2016/05/News%20Articles/2126902 http://cds.cern.ch/journal/CERNBulletin/2016/05/News%20Artic...

That's traffic analysis, not traffic metadata retention. The problem is not the computational load, but the storage capacity and bandwidth requirements. And what is stored at CERN is the analysis results of the data, not the data history itself. Also it's one TiB/day in total for the whole of CERN.

  _All_ this data is stored for one year.

    > _All_ this data is stored for one year. Which refers to the result of the analysis. If CERN would retain all the data that crosses their network, or just the metadata they'd have to roll in truckloads of HDDs each day.
