asterisk users - Oct 2004 - Multiple Bandwidth Providers and Asterisk

This is a possible near future situation of ours: 10 different bandwidth
providers, each providing 2 T1s. 15 different call carriers about the US.

Each BW provider has its own Cisco 2610 into which the T1s go. Then 1
ethernet cable from each router goes into * box.

If caller A needs to go to carrier 1, can * tell how many calls are already
on ethernet cable #2?
Cause if ether #2 (the default) is full/close to full, * needs to send
caller A to carrier 1 via a different ethernet port/provider.

Any one in a similar situation with multiple bandwidth providers? How do you
handle BW choice?

Normally this would be done in a router. But the routers don't handle
"calls", they handle "packets". So if the router sends
packet #1 of call #1
out 1 provider and packet #2 out another, you get jitter.

Help/Advice appreciated.

Thanks,
Matthew

Just to make sure I understand: 

You want to know how to load balance your bandwidth among a number 
of ethernet interfaces with the emphasis on making sure that once a 
connection is established that it will use the same interface, right?  

If so here are a couple of links:

* http://lartc.org/howto/ - Linux Advanced Routing & Traffic Control
Howto
* http://lartc.org/howto/lartc.rpdb.multiple-links.html - Specific page 
	regarding multiple links

If that isn't your goal please disregard.

Good luck,
