  1. Reducing Flow-Completion Time for Small Flows by Modifying Slow-Start Affan Rauf (05030063)

  2. Problem • Slow start stretches a small over several RTTs even if they are capable to complete in few • About 70% of the gateway traffic consists of Web transfers • About 85% of the packets are transferred by the server while flows are still in their slow start phase

  3. Recent Suggestions • RFC 3390 TCP’s initial window increased to 2-4 segments • Network Adaptive TCP Slow Start (closest to the idea I had in mind) Uses past history from other connections and the file size

  4. My Hypothesis • Why can’t we can guess if the congestion is decreasing based upon a few recent round trip delays • Being optimistic we can increase the window size e.g. by extrapolation

  5. Issues • How much to increase congestion window without adding to the congestion? • Is linear interpolation and the gradient of the line a good estimate? • Can we scale it for longer flows?

  6. Line of Action • Comparison with RFC 3390’s results (based on Flow-completion time) • Effect on throughput in the presence of AQM techniques.

  7. If you found that useless, please tell me NOW! Questions?
