Hi everyone, In the last OVN Community Meeting we talked about synchronizing connection tracking information.
Our primary goal is to ensure seamless failover during maintenance (preserve stateful connections to reduce disruptions) We have identified two key use cases, with the first being our priority: - Live Migration of VMs(openstack) with Multi-Chassis Port Bindings in OVN - LRP Failover on Gateway Chassis As we plan to move to DPDK in the future, the ideal mechanism would support the kernel and userspace datapath. During our conversation we had the following thoughts: - external agent such as conntrackd? how does it work with dpdk? - some syncing logic in ovs-vswitchd between nodes Has anyone else encountered this problem or has already a solution for dpdk conntrack sync Are there any existing or planned OVN/OVS features that might help address this? What architectural approach or layer do you think would be most suitable for this functionality? We are reaching out to the ovs community to gather more ideas and to hear your thoughts on this. -Max
