[ndnSIM] Measuring a download time

Hi Sharvari,

There is no simple answer to your question.  Download times, besides multi/single path forwarding depends on client request pattern and congestion control (hop-by-hop and end-to-end).

ConsumerCbr may not be a great consumer to measure what you want, as it is sends interest at constant rate.  If it can retrieve set of data packets over single path, it will take the same amount of time (minus reduced interest reexpressing) to fetch of multipath.   You can try ConsumerWindow, but it has a very rudimentary logic that is trying to adjust client strategy to the available network capacity.

May be you should try to use different measurement parameter, which shows the effect of mutlipath strategy, without adding dependency on client requests.
