Re: [ledbat] New Version Notification for draft-ietf-ledbat-congestion-07.txt

[Rolf Winter <[e-mail]>]

Hello,

could Dario, Bob, Gorry and Arjuna please check whether your comments are resolved. This would help us make progress.

Thanks,


Rolf

> Abstract:
>     LEDBAT is an experimental delay-based congestion control algorithm
>     that attempts to utilize the available bandwidth on an end-to-end
>     path while limiting the consequent increase in queueing delay on
> the
>     path.  LEDBAT uses changes in one-way delay measurements to limit
>     congestion that the flow itself induces in the network.  LEDBAT is
>     designed for use by background bulk-transfer applications; it is
>     designed to be no more aggressive than TCP congestion control and
> to
>     yield in the presence of any competing flows when latency builds,
>     thus limiting interference with the network performance of the
>     competing flows.
