What Sadus is looking for is called link equalization IIRC. It's where you use different links of varying speeds and tie them up together for use as one connection. Traditionaly you'd use a round-robin method of sending packets out over multiple default routes. This is not always ideal, you'd need some kind of intelligence to spread the load more realistically, and the Linux EQL driver and TEQL device allows for that to happen. These two know the speed of each link in the equation, and delivers better control, albeit not perfect. Now, Sadus, my apologies. The thread I was referring to was on the LARTC list. The LARTC list is in any case the better list for these kinds of questions. iptables cannot perform this task, you need the iproute2 package, and LARTc is the definitive source for information and discussions on the topic. The website is http://lartc.org/ and http://lartc.org/howto. The thread I was referring to is available at http://marc.theaimsgroup.com/?l=lartc&m=111429252500344&w=2 Hope this helps, and share your experiences if you don't mind! > > > thanks > > > > On Sun, 2005-05-22 at 00:33 +0200, Kenneth Kalmer wrote: > > > On 5/21/05, Sadus . <sadus@xxxxxxxxxxxx> wrote: > > > > Hello, > > > > If i want to search for HOWTOs that can enable me to merge the > > > > connection speed of multiple providers (inboud/outbound), what should i > > > > search for? > > > > > > The nano howto if I'm not mistaken, and have a look at the eql qdisc > > > and teql device. > > > > > > > > > > > what i mean by merging is, lets say my connection is shaped at 100K and > > > > the other is also shaped at 100K, i want to be able using the 2 ISPs to > > > > have 200K (in/out), > > > > > > > > Does anyone have a HOWTO or Article about that Matter? > > > > > > I asked a similar question in the list not too long ago.
