Neutron 里面的 security group 是作用在 VM 对应的 neutron port 上面,因为 OVS internal port 不能经过 Linux 协议栈,所以不能直接通过 iptables 来做 security group,加上 OVS 2.4.0 以前都不支持 conntrack(Linux kernel netfiler 的一个功能,可以记录连接状态,是有状态访问控制和 NAT 的必备条件),如果单独...
Northbound DB收集业务数据,而Southbound DB收集底层网络的实时数据,这和ODL MD-SAL中DB的设计是类似的,尽管OVN中的Northbound DB和Southbound DB目前好像是用一个ovsdb-server实例实现的。 具体点说,Northbound DB负责把Neutron中的数据结构(如network、subnet、port、securitygroup等等)转换为OVN的数据结构(如logical swi...
