Hi Jonathan Thanks for your quick answer. REally appreciate it!!! I wil try later the cake statement (is it the same as codel)?. I am starting with Codel. So I need to have a better understanding of codel. I have the following scenario [image: image.png] Where client asks for a FTP file to server. Link between router-server has a 150MBit speed with a delay of 250 ms. Then link between client and router has 10 Mbit and the Codel algorithm. So I am checking the differences between having codel or not. *Do you have an advice to have a good scenario for testing Codel properly? Or a document to know how the differences parameter can affect to the communication?* In my scenario it seems it is better not having Codel. See attached ClientFTPCodelNO-NO-NO (nocodel) versus ClientFtpCodel1000.. where a Codel Algorithm of 1000 packets, 13 ms target and 100 interval is configured Regards.
