[Tmrg] Towards a Common TCP Evaluation Suite - traffic generator question

[Lachlan Andrew]

Greetings,

I've contacted the Tmix team asking for their measured traces, and
hope to generate suitable short traces from them.  If they don't reply
soon, I'll try to generate some synthetic traffic (probably Poisson
arrivals and Pareto file sizes).

However, if we need to resort to that, I'd suggest that we go back to
using  Harpoon  which actually exists for Linux.  The minor increase
in realism it allows will be lost if we have to use synthetic data
anyway.

The Full-TCP issue also applies to the main set of "general tests".
One one hand, I think that the authors of a modification to TCP should
be willing to write it for the Full-TCP module.  On the other hand,
this is another reason to go back to  Harpoon,  especially if people
want to compare their enhancements to the existing enhancements.

Cheers,
Lachlan
