Megaflow cache
WebReprocessing a logical-flow uses a new conjunction ID (unless logical-flow cache is enabled) => All the M + N + 1 flows are changed => all deleted and reinstalled to OVS Control plane latency Dataplane impact - megaflow cache churns Now Logical-flow uuid based consistent conjunction ID allocation algorithm

Hidden flows in OVS are used by the controller to talk to the switch, you typically won't want these to show up in Netflow hence they are hidden by default. If you use the command; 'ovs-ofctl dump-flows br' you will get all flows except the hidden ones, if you use the command; 'ovs-appctl bridge/dump-flows br' you'll also get the hidden ones.
WebTSS算法原理. OVS 里的dpcls查询就是使用了元组空间搜索算法（Tuple Space Search，简称 TSS）进行流表查找， 元组空间搜索算法的核心思想是，把所有规则按照每个字段的前缀长度进行组合，并划分为不同的元组中，然后在这些元组集合中进行哈希查找 。. 我们举例 ... http://www.openvswitch.org/support/ovscon2024/
