Hello, everyone!

The goal of Open vSwitch is to make a multi-layer virtual switch with product quality.

OpenvSwitch, or OVS for short, is a virtual switching software used primarily for virtual machine VM environments as a virtual switch.
Xen/XenServer, KVM, and VirtualBox are multiple virtualization technologies.

The composition of OpenvSwitch

Ovs-vswitchd: daemon, implements switching, and implements stream-based exchange flow-based with Linux kernel compatible modules 

Switching.

Ovsdb-server: Lightweight database service, which mainly saves the configuration information of the entire OVS, including interface, exchange content, VLAN
Ah, wait. Ovs-vswitchd works based on the configuration information in the database.

Ovs-dpctl: A tool to configure the switch kernel module to control forwarding rules.

Ovs-vsctl: mainly to get or change the configuration information of ovs-vswitchd, this tool will update the number in ovsdb-server
According to the library.

Ovs-appctl: Mainly to send commands to the OVS daemon, generally not used.

Ovsdbmonitor: GUI tool to display data information in ovsdb-server.

Ovs-controller: a simple OpenFlow controller

Ovs-ofctl: Used to control the content of the flow table when OVS works as an OpenFlow switch.

That's all, thanks!
