I guess it can't hurt, but I'm not sure of the value. We only shift traffic if there's a significant amount of it, in which case the next-hop switch will find out that the MAC has moved at just the right time anyhow. I guess it will make a difference if the traffic has actually stopped abruptly and we're just exponentially timing out the byte counter, so maybe it's worthwhile for that reason. Did you look at Citrix's kernel implementation of SLB to see if it does that? If it doesn't, should we follow the implementation or the documentation? _______________________________________________ dev mailing list [email protected] http://openvswitch.org/mailman/listinfo/dev
