The fact that they could claim unused and available bandwidth doesn't change the fact that they are lower priority than conventional TCP. I agree with your point that this could in fact rapidly claim bandwidth faster than conventional TCP depending on the design but the priority consideration with relation to conventional TCP still remains. I was wondering how different or aligned the goals of TANA are with something like TCP-LP which also yields to conventional TCP but uses the available Unused bandwidth. Are we differentiating it based on the fact that TANA would be more aggressive in reclaiming unused bandwidth to the point of being higher throughput than a conventional TCP flow? Or is TCP-LP one of the solution points for consideration. Thanks Saumitra www.saumitra.info<http://www.saumitra.info>
