In addition to supporting a variety of features 24 expected in a traditional hardware switch, it enables fine-grained 25 programmatic extension and flow-based control of the network. This 26 control is useful in a wide variety of applications but is 27 particularly important in multi-server virtualization deployments, 28 which are often characterized by highly dynamic endpoints and the 29 need to maintain logical abstractions for multiple tenants. 30 31 The Open vSwitch datapath provides an in-kernel fast path for packet 32 forwarding. It is complemented by a userspace daemon, ovs-vswitchd, 33 which is able to accept configuration from a variety of sources and 34 translate it into packet processing rules. 35 36 See http://openvswitch.org for more information and userspace 37 utilities. 38 39 To compile this code as a module, choose M here: the module will be 40 called openvswitch. 41 42 If unsure, say N. 43
