Hi All, I am working on splitting traffic by using multiple buckets in groups with select type. Some previous discussions related in the mailing list helped me understand it better, however, I would like to confirm a couple of facts.
1. Is the bucket selection only based on flows? If I am trying to split the udp traffic for a same source-destination pair in a forwarding switch to multiple output ports, does that mean the only way to enable buckets selection is to divide the udp traffic into multiple flows from the source host (e.g. use different udp source ports)? 2. I am using ovs 2.3.1. It does not support unequal weights for buckets, doesn't it? I found a project described on the wiki below, which implemented feature of unequal weights in group table. I followed the setup but only one bucket got selected. The author also posted in ovs mailing list with the similar question. I am wondering if the reason is because there is only one flow in the test. https://github.com/saeenali/openvswitch/wiki/Stochastic-Switching-using-Open-vSwitch-in-Mininet http://openvswitch.org/pipermail/dev/2014-February/036800.html 3. Suppose the bucket is selected based on flows and buckets have equal weight with actions of different output ports. In order to make sure load balancing is achieved, my understanding is we have to assume those flows have equal flow rate, because the selection method only hashes flows evenly. Is that correct? (I posted a question in dev mailing list, but later realized probably I had better ask here, sorry for that!) Thanks, Ning
