AW: [squid-users] Re:[squid-users] Re:Re: [squid-users] How to setup two ADSL line on a single linux box?

Ok, for now i don't paste any answers, but i think it was very useful even
it's posted in the squid list isn't?

Agreed.

However, with two dry loops or live lines (or more) it is possible to
bond the circuits together for aggregate bandwidth. That being said,
the sum is not simply the bandwidth of each link * number of links.
There is some bandwidth lost to the overhead of the bonding.

FWIW, here is an isp in UK which does just this:
http://www.upstreaminter.net/

But this is really straying from the topic of squid ;-)

Note this remark

What this will not do:
"This type of spanning will not aggregate bandwidth for a single user. By this 
I mean that if you have two 5 meg DSLs you won't magically have a single 10 meg 
connection. This is because it routes destination IPs via one of the two ISP 
connections, so if you're downloading a single file from freshmeat.com all 
requests for freshmeat.com will go in and out one of the two interfaces (until 
the kernel's routing cache expires). It will not try to open two connections to 
the IP using both lines at the same time."

as i described below:

it's not possible (at the moment) to open 2 ADSL Ports on the same telefony 
wire... so if you have 2 5 MB Lines you will have still 2 5MB Lines after 
implementing this solution more not) If the Line is open (on the DSLAM which is 
managed by the telefony carrier, you have normally one port configured for ADSL)

So its a illusion to think, that you can do this
