Guys,
Please don't get pissed off reading my signature... :)
It is very simple logic. What I did was simplistic but it gave what my
boss wanted rather than what I wanted. :)
Anyway you just switch between the 7 links when you are sending data in
a round robin fashion. Of course there is more to it. But if I get 7 IP
datagrams , I shove it on each of the 7 links and the next packet goes thro'
the first link and so on.
TCP takes care of assembling the packets as long as all interfaces are
on the same network. You might want to take care of some routing details here.
If you do this thing at the other end, then your download will get
aggregated but if you want this happening for both uploads and downloads do it
at both ends.
My problem space was completely different and it was no UNIX at all.
So I am sure when there are standard RFC compliant protocols to achieve
your goal, you should go for that instead.
If a link goes down, you ignore that. I did that over wireless links,
so it may not apply in your case.
Please try and read up either of the protocols I mentioned in the last
mail(MLPPP & BGP).
Best of luck!
regards,
Girish
