Re: [PATCH] ipvs: Add traffic statistic up even it is VS/DR or VS/TUN mode

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



especially in public cloud case, statistic is related to monitorring
and billing , both ingress and egress packets will go throught ipvs,
even dr/tun mode.
in dr/tun mode, ipvs need to do nothing except  statistic, so
skb->ipvs_property = 1

regards
