Re: [SLUG] Two modems, how to split the data stream?
> how do I split the data stream when using two modems?
Look on the web for a Linux product called EQL. I have never set
this up but it looks like it should work. Basically it puts up
a single slip interface as the default gateway on your linux host.
It catches the packets on the other side and routes them down
alternate modems. However the source address of all packets in a
tcp/ip session are all set to the same address, thus the returning
packets all come back on the one modem. Thus most of the benefit is
for outbound traffic. I "believe" however that if you have multiple
tcp/ip sessions running concurrently it will give different tcp/ip
sessions alternate return addresses, which means that a web page with
lots of images (I.E multiple tcp/ip sessions) should download via
both modems. Also beneficial if your linux box is a dial-up gateway
for you local lan. EQL doesn't require any co-operation from the
ISP and in fact it doesn't even matter if the modems are connected
to different ISP's.
BUT Like I said, that's the theory, I've not tried the practise.
The other product is multippp or mppp. It does require support at
the other end. I know less about this than EQL but the theory
is sound, basically each end of the dual connection binds both
modem lines to the one IP address. Obviously this means that the
dialup connection has to be to the same NAS.
If you do find out anything useful, please send it on. I'd like to
get this working as I'm one of those poor people whom telstra adsl
and optus cable forgot.
