Hi All, Maybe someone will find this useful: Attached is a flent config for exercising all of cake's diffserv tins in diffserv4 mode. Very much based on rrul, in essence it runs at least 1 tcp stream in each tin. 2 streams are used in each tin for upload, only 1 stream per tin for download - I was interested in upload fairness between tins & flows within tins in a 'full on, everyone competing for everything' type test. Well, it's kept me entertained for a few minutes :-) Kevin
