Hello. I''m newbie with QoS. I read some articles and I have a question
on You. If you have time to spare, it would be great
if you reply. Here is my problem. I''m on wireless network(no earnig
comunity). We got 2/2Mbit(soon 4/4) for 100 people(sharing link). Not long ago
people start
screaming that their games don''t work good(lagging). So I add to our
qos class games with highest prio. I don''t know much about game
traffic. So I add this class:
$TC class add dev eth0 parent 1:1 classid 1:3 htb rate 64kbit ceil 256kbit
burst 6k cburst 6k prio 0
Then I add every game port(War3 6112,CS 27015-6, OU, Quake3 etc.) :
$TC filter add dev eth0 parent 1:0 protocol ip prio 1 u32 match ip sport 6112
0xffff match ip protocol 0x11 0xff flowid 1:3
What do you think about this configuration? Do you know better setting for
gaming traffic on share connection line? I''d like to know your
opinions. I''m appreciating your comments.
Thank you in advance

I''m appreciating your comments. > Thank you in advanceI came to a similar conclusion with regard to games, and set up something similar myself. So far it''s worked ok. The only thing to watch out for is what happens to your latency as bandwidth levels approach the full capacity of your connection. Even if game traffic has high priority that won''t save you from high latency when the connection is saturated. You may have to reduce your overall ceil from 2048 to, say, 1900. Experiment to find a good value. -Corey

I''m appreciating your comments.I wouldn''t send interactive type traffic to sfq - perturb causes packet reordering, it''s meant for bulk traffic really. I would make one class for all interactive types and give it a much higher rate rather than spliting into game, ping, ssh etc and having low rates for each. Are the 2/2 and 4/4 internet link - you are OK for bandwidth on wireless? Andy.

I understand that sfq is not the best. Should I create interactive class with pfifo queue discipline and what about parent class? Leave it sfq? Our bandwith is fine and 2/2 is guaranteed internet link. Thx in advance

I understand that sfq is not the best. Should I create interactive class with pfifo queue disciplineI would - in a way it doesn''t matter that much as you should hope to have rates high enough so that interactive doesn''t queue anyway.>and what about parent class? Leave it sfq?Bulk traffic classes are OK for sfq - parent class doesn''t have qdisc only leafs.> Our bandwith is fine and 2/2 is guaranteed internet link.OK - do you shape incoming aswell. Andy.
