Hi Varun, This looks interesting - it would be nice to see self-fairness performance as well. What model did you use for the codec in ns2 (EvalVid or mpeg_traffic or other) ? I (and probably others) would be interested to have access to the ns2 RRTCC implementation - would it possible to release the source code? (Though I'd be surprised if Google haven't already implemented it in ns2/3 already as well ...) Thanks, Piers On 2 Aug 2012, at 08:47, Varun Singh wrote:
Hi,
Following up on the discussion of fairness between interactive real-time flows and TCP. I've implemented the RRTCC in NS-2 and attached within are the preliminary results.
The scenarios that we simulated are: 1. RRTCC flow shares a bottleneck with short TCP. 2. two RRTCC flows share a bottleneck with with short TCP flows.
The short TCP flows are modelled as on/off flows. The size of the data is obtained from a uniform distribution between 100KB and 1.5MB, and the idle periods are obtained from an exponential distribution with the mean as 10.
The results are available as a short presentation at: http://bit.ly/rrtcc-tcp
I would appreciate any comments and/or feedback.
Cheers, Varun _______________________________________________ Rtp-congestion mailing list Rtp-congestion@alvestrand.no http://www.alvestrand.no/mailman/listinfo/rtp-congestion
