I recalled a discussion of manipulating outgoing tcp windows in order to control return tcp traffic. I finally found at least some of that discussion in a thread with the subject above (of this message). But I thought someone announced an implementation and I don''t see it under this thread. If anyone else remembers or knows where I should look for it, please let me know. I''m also interested in other discussion of the idea and in implementations of related ideas such as delaying the acks etc.

You can get the paper and slides from the following URL: http://www.ens-lyon.fr/LIP/RESO/pfldnet2005/TechnicalProgram.php This software called PSPacer is avaiable. But, I am sorry, the current release version does not support TCP window based pacing whereas it supports static pacing. The web page is: http://www.gridmpi.org/ Thanks, TAKANO Ryousei.

PSPacer basically assumes the use of end-to-end traffic engineering. (PSPacer can also regulate bandwidth of through traffic at static target transmission rate on routers.) Thanks, TAKANO Ryousei
