Thanks - so you are suggesting we enable 802.3 flow-control /
pause-frames?
(it's currently disabled)

Subject: Re: TCP congestion control for fast, short-distance networks ?
* [EMAIL PROTECTED] <[EMAIL PROTECTED]> [070404 18:29]:
Hello,
We are currently using both 1 Gb & 10 Gb links, that interconnect
several
servers that are very *local* to
each other.
Typical RTT times range from 0.2 ms - 0.3 ms.
We are currently using TCP reno - is there a more suitable congestion
control
algorithm for our
application,
especially using the 10 Gb links ?
(Most of the High-Speed TCP algorithms seem suitable for large RTT,
long-distance networks).
I'm not aware of any tests for high speed links with very low RTTs, but
I suspect that the new algorithms will not change much, if the
connections you have are indeed local than the Ethernet pause mechanism
is more effective for the flow control you need.
