PCC PROBLEM

rini · April 1, 2011, 8:16pm

hi there
I have 5xDSL lines

conn1 5 Mbps
conn2 5 Mbps
conn3 3.5 Mbps
conn4 3.5 Mbps
conn5 2.5 Mbps

I see a problem that all of 5 dsl lines get the same traffic

/ip firewall mangle export

I know that my problem is to per connection classifier denominator/remainder

please tell me what should i put to this denominator/reminder for the 5 dsl lines i have

fewi · April 1, 2011, 8:23pm

For a completely even split, the smallest common denominator is 0.5 - 10 lines for 5 meg, 7 lines for 3.5 meg, 5 lines for 2.5 meg. That doesn’t scale well as that results in 39 lines total.

I would think it better to live with 2.5 meg splits, which will leave your 3.5 meg lines slightly underutilized:

add action=mark-connection chain=prerouting comment="" connection-mark=no-mark disabled=no dst-address-type=!local in-interface=LAN new-connection-mark=conn1 passthrough=yes per-connection-classifier=both-addresses:7/0

add action=mark-connection chain=prerouting comment="" connection-mark=no-mark disabled=no dst-address-type=!local in-interface=LAN new-connection-mark=conn5 passthrough=yes per-connection-classifier=both-addresses:7/6

For reference, the 39 lines would be:

But again: I wouldn’t use that.

On a sidenote, I hope this makes it clear how to derive those values. This is basic math, it’s very, very simple. You’re trying to find the smallest number that that 5, 3.5 and 2.5 cleanly divide by. That is 0.5. Then you need 5/0.5 = 10 lines for 5 meg pipes, 3.5/0.5 = 7 lines for 3.5 meg pipes, etc.

In your case that results in too many lines of configuration for packets to have to traverse, so it’s better to find a closer value that doesn’t completely fairly spread traffic, but results in less configuration. That value is 2.5 - it’s a clean division for 5 and 2.5, and 3.5 is a pretty close match for a factor of 1.

fewi i hope for you to respond

i understand this
please kindly tell me what is the best configuration for me?
you write a lot of rules here.
please please help me

if i make the all 5 lines 3.5mb what configuration can i put ?

I understand now
very very thanks fewi
