Hi all, I'm testing "weighted select groups" behaviour on ovs2.5 stable, I'm using this command: ovs-ofctl -O OpenFlow15 add-group ovs0 "group_id=1,type=select, selection_method=hash,fields(nw_src,nw_dst,tcp_src,tcp_dst), bucket=bucket_id=1,actions=output:11,weight=$1, bucket=bucket_id=2,actions=output:12,weight=$2" $1 and $2 correspond to the weights column below: Weights Measured Deviation 50/50 50/50 0 40/60 34/66 6 30/70 22/78 8 20/80 13/87 7 10/90 5.6/94.4 4.4 50/950 97/3 2 Traffic pattern (using pktgen_dpdk and only tcp packets): dst.ip 2.0.0.1 -> 2.255.255.255 src.ip 1.0.0.1 -> 1.255.255.255 dst.port 1 -> 65000 src.port 1 -> 65000 pkt.size 1500 I believed that given enough traffic diversity, weights would be closer to the configured ones! I tested against narrower and more realistic traffic patterns but still having similar results, any suggestions? Thanks, Ibrahim
