Hi , i am trying to understand how RED queue discipline works but i am having a few troubles. The parameters are MIN , MAX , LIMIT , BURST I put LIMIT = 64Kb, so if i am not wrong it should PDROP anything over this value , right ? i put MIN = 8Kb , so no drops at all below this value, right ? i put MAX = 16Kb, starts to early drop anything above this using probability P. I put probability at 0.5 [very high , just for test] i PUT burst at 20 [actually , no idea what really put in here] but after a while downloading at full speed i still get no drops at all. Using 50% probability i should get at least 1 early drop shouldnt i ? qdisc red 3: limit 64Kb min 8Kb max 16Kb Sent 5023410 bytes 3817 pkts (dropped 0, overlimits 0) marked 0 early 0 pdrop 0 other 0 -- []''s Salatiel "O maior prazer do inteligente é bancar o idiota diante de um idiota que banca o inteligente".
