Create a Linux packet splitter

Question

I am looking for some hints to build a network packet splitter. What i want is some sort of tools/code that split the packets of a logic link (tcp/ip connection for ex.) over several network interfaces.

I used with success the Linux bonding driver, however the best performance is only achieved when the bandwidth/latency of the several network interfaces is similar, since the bonding driver uses round robin packet splitting.

Anyone know any tool that can effectively split packets (not logical links) over network interfaces using a weighted manner, instead of round robin manner?

Answer 1

You can use sysfs to change your bonding mode to a more effective choice for your setup.
/sys/class/net/bond0/bonding/mode

You may have some luck also changing the queue_id in the same place to make different adapters more important.

Take a look at the Linux bonding documentation for information about the settings.
