Sorry... previous mail was sent unintentionally in HTML format... ************************************************ Has anyone successfully patched HFSC (ported by Alex Goldney) into linux kernel and tested it? I''m doing an analysis on the various queueing algo (red,cbq,wrr,tbf), Diffserv and I hope to put hfsc into the picture... There is also CSZ but it was claimed that it is inoperational. is this still true?? Regards.
