CSEC OLYMPIA software analyzed
The Top Level Communications blog has published a detailed and convincing analysis of the functions and capabilities of CSEC's OLYMPIA target development software, as revealed in a leaked June 2012 powerpoint presentation (part of the Snowden documents): OLYMPIA: How Canada's CSEC maps phone and internet connections (13 March 2014).
The topics discussed are way beyond my very limited technical knowledge, so there's very little I can add, but FWIW the explanations provided do seem to ring true.
One small note: While I agree that the TAO referred to in the presentation is most likely NSA's Tailored Access Operations unit, there is some reason to believe that CSEC's parallel unit may also use the name "Tailored Access".
