In addition to supporting a variety of features 24ccb1352eSJesse Gross expected in a traditional hardware switch, it enables fine-grained 25ccb1352eSJesse Gross programmatic extension and flow-based control of the network. This 26ccb1352eSJesse Gross control is useful in a wide variety of applications but is 27ccb1352eSJesse Gross particularly important in multi-server virtualization deployments, 28ccb1352eSJesse Gross which are often characterized by highly dynamic endpoints and the 29ccb1352eSJesse Gross need to maintain logical abstractions for multiple tenants. 30ccb1352eSJesse Gross 31ccb1352eSJesse Gross The Open vSwitch datapath provides an in-kernel fast path for packet 32ccb1352eSJesse Gross forwarding. It is complemented by a userspace daemon, ovs-vswitchd, 33ccb1352eSJesse Gross which is able to accept configuration from a variety of sources and 34ccb1352eSJesse Gross translate it into packet processing rules. 35ccb1352eSJesse Gross 36ccb1352eSJesse Gross See http://openvswitch.org for more information and userspace 37ccb1352eSJesse Gross utilities. 38ccb1352eSJesse Gross 39ccb1352eSJesse Gross To compile this code as a module, choose M here: the module will be 40ccb1352eSJesse Gross called openvswitch. 41ccb1352eSJesse Gross 42ccb1352eSJesse Gross If unsure, say N. 43
