channel bonding

[rweidman at watson.chemical.missouri.edu]

We have successfully configured a 4 node beowulf cluster on our way to 20
nodes. We are interested in experimenting with channel bonding.

Which kernel is best to implement channel bonding? 
Are  there any kernels that has what is needed to implement channel
bonding and where is the best palce to find information on channel
bonding?

thank you
