Hi all and Stef
i been working with TC to get of the setup to make my network stable with
Quality
i was testing with my PC, limit rate and Ceil rate are same
when i try to upload and download the data from my test FTP Server
my setuup looks like this
MyIP----Crosscable--eth1(Bridge(br0)eth0---Switch--FtpServer
|
|
--------------G/W Router----Internet
1. iam able to achive the data control while iam upload the data from myip
to ftp Server, and same back
2. but i get lot of latency while iam upload the data or downloading the
data like 1000ms
3. when there is no data transfer the latency is 2ms
4. when iam upload or downloading the data, when i try to retrive pop
access, i get message from out look express wait, until i complete my upload
and download
i keep getting wait, once its finished, then iam able to get all the
mails which is pending in my box
5. but iam looking for good latency,
6. i have several kind of clients in the network, where iam looking to
control up+down b/w ( since IMQ is not working with me for total B/W)
7. iam looking to give to the customer raw 64kbps or 128kbps.... do i need
to shape the traffic while iam giving them RAW
8. what is the best ways to do the shaping id required, i just use SFQ, for
the classid to check
my script is below for test setup
thanks
