[LARTC] Two kinds of bandwidth ...

[Aldrin Martoq A. agm@cec.uchile.cl]

<PRE>Last week someone in my localnetwork &quot;abused&quot; from our link, making
everything slow... So I want to put the current Linux router as a traffic
shaper. The setup is:
                                                    +--- 128Kbit
                                                    |    &quot;International&quot;
Local net --- [Linux router with    ] -- ISP -- [magic routers]
              [transparent www proxy]               |
                                                    +--- 10MBit
                                                         &quot;National&quot;

It happens that 99.99% of the traffic is download of www, so the squid
proxy serves it automagically.

The problem is that the ISP link is a &quot;dual&quot; contract. 10MBit for
&quot;National&quot; traffic (By law in my country, all ISPs must be inter-connected
so the national traffic is not so bad). But there is only 128KBit for
&quot;International&quot; traffic, and that is managed by the &quot;magic routers&quot; out of
my access and control.

So I want to distribute the poor &quot;International&quot; traffic fairly in my
local network without slowing down the &quot;National&quot; traffic and having no
idea of which packet goes through national or International, a priori
(maybe I can ask my ISP); and everything pass between the squid proxy.

Any ideas? (Besides education). Is just impossible?
If I get the &quot;magic routers&quot; tables, can I do something useful ?
