[LARTC] Per-Packet Load Sharing

[LARTC] Per-Packet Load Sharing

Hi All,
 
Have a quick question, I have been looking / trying for some time now to
figure out away to do Per-Packet Load sharing.  What I have is two
10Mbps Connection between two buildings, I want to configure the router
on each side to load share on a per-packet basis.  Currently I can do
this with some Cisco routers, and simply enable load share per packet on
the interfaces.  Is there a way to do this with Linux somehow?  I have
tried all kinds of patches, etc that I have found but with no success.  
 
I may also want to use this across other types of interfaces like
multiple ppp links (no multilink, just two ppp links) so I guess I need
it to be based on the routing, not on a bonded interface, like it does
with TEQL, etc.
 
Thanks in advance.

If they're both linux, would this work:

Host0: Bridge interface #1 with interface #2. This assumes they're on
the same subnet
Host1: Bridge interface #1 with interface #2. This assumes they're on
the same subnet

On each machine add the following:

iptables -t mangle -m nth --every 2 --packet 0 -m mark ${MY_FIRST_ROUTE}
iptables -t mangle -m nth --every 2 --packet 1 -m mark
${MY_SECOND_ROUTE}

Add ip rule's and ip route's to facilitate the forwarding of the packets
through the lines.
Since the route to whatever you are travelling to is the same on both
physical interfaces, you'll need to specify the dev ${my_if1} or
${my-if2} in order to properly route through the correct device.

Hi, do u know how to implement per-connection load-sharing over bridge 
into linux?

thanks...
