Hi:
I've just spend many time probing and searching for equalize traffic load
between som routers.
For example this scenary:
a lot of bits_of_traffic-hungry machines in a LAN
two or many ISDN routers to the internet attached to a LAN
Would it be possible to use a Linux Load Balancer box to redirect traffic to
different routers as the traffic in the LAN increases?, so you can a certain
bandwith/user when the number of users of internet increases?. The idea is use
ISDN b-channels when its really necesary, and don't have to pay more than
necesary.
I think that something that:
In the load balancer 10.1.2.254 put these lines:
ipfwadm -F -a m 10.1.2.0/24 -D 0.0.0.0/0
ippfvsadm -A -t 0.0.0.0/0:80 -R 10.1.2.1:80
ippfvsadm -A -t 0.0.0.0/0:80 -R 10.1.2.2:80
Where:
10.1.2.254 is the default gateway for the 10.1.2.0 subnet
10.1.2.1
10.1.2.2 are ISDN dial on demad routers calling to a ISP
Then when a user in 10.1.2.0 try to connect to a outside IP destination the
load balancer redirect it to one of the ISDN router.
With a correct load-balance algorythm in the load balancer box this should
work as I describe, using a new ISDN router when a lot of users are using the
first and redirecting new users to the second ISDN router.
Is it possible?
if not ,could be implemented in a near future?
Is there another solution?, I don't want to buy a ISDN primary access router
with intelligent load balancing to do it, I wan't to do it with my linux
system.
Thanks in advance.
Andres.
