Hi Jerome, > What protocol are you considering to duplicate states? I plan to use no protocol. Instead of that, I will use 2 methods for member selection (Determining which one is active or standby) First one is liveness-probe (health check) on the VPP machine. It will automatically switch active member. Second one is manipulation via API by outer control-plane, which manage any requests. I'll do PoC on my machine whether it will work as I expected.
Thanks, Yusuke. ________________________________ 差出人: Jerome Tollet (jtollet) <jtol...@cisco.com> 送信日時: 2019年5月9日 18:07 宛先: 立見 祐介; vpp-dev@lists.fd.io 件名: Re: [vpp-dev] VPP Load Balancer with active-standby Hi Yusuke Tatsumi, What protocol are you considering to duplicate states? Jerome De : <vpp-dev@lists.fd.io> au nom de Yusuke Tatsumi <ytats...@yahoo-corp.jp> Date : mercredi 8 mai 2019 à 07:24 À : "vpp-dev@lists.fd.io" <vpp-dev@lists.fd.io> Objet : [vpp-dev] VPP Load Balancer with active-standby Hi all, We've already used VPP LB plugin as active-active L3DSR load balancer, and It works well in our environment. In addition to the above, I'm now interested in supporting active-standby load balancer for some particular cases, mysql for example which support only single active node. So I plan to enhance LB feature to support active-standby. In consideration of robustness of feature, adding member-selection-weight function is suitable I think. With this method, VPP will do as follows, - no weight setting (default): active-active - weighted setting (ex. 6:4): active-active with 6:4 weighted - weighted setting (ex. 10:0): active-standby Do you have any option or much good idea?
