WebSep 4, 2015 · The threshold is a type of limit on the number of flows that are cached in the kernel. OVS will handle as many flows as can be processed through ovs-vswitchd. If the number of newly created connections reaches this limit, in a 5 second window, OvS attempts to keep the memory consumption under the limit by evicting older flow entries. Webovs-vswitchd in particular accepts a number of additional commands documented in ovs-vswitchd(8). The ovs-appctl program provides a simple way to invoke these commands. The command to be sent is specified on ovs-appctl's command line as non-option arguments. ovs-appctl sends the command and prints the daemon's response on standard output.
