Please look at the ovs-ofctl man page. You should be able to figure it out with "add-flow" commands with appropriate matches and actions. They're of the form: ovs-ofctl add-flow ,actions= So if you want to match on the tos bits, you can use the "nw_tos" field. To modify the tos bit

I can't reduce the number of hops. We're doing large scale emulations using topologies that are synthesised from the Rocketfuel dataset. Therefore, the design can't be more efficient. The example above was used only to explain the conditions under which this problem occurs. All broadcast traffic

If you remove it at some point the machine will crash. I think your time is better spent reducing the number of hops that you have. I don't know what your goal is but your current design is extremely inefficient. On Tue, Jul 17, 2012 at 7:41 PM, Vjekoslav Brajkovic wrote: > Would you happen to
