In addition to supporting a variety of features 21*4882a593Smuzhiyun expected in a traditional hardware switch, it enables fine-grained 22*4882a593Smuzhiyun programmatic extension and flow-based control of the network. This 23*4882a593Smuzhiyun control is useful in a wide variety of applications but is 24*4882a593Smuzhiyun particularly important in multi-server virtualization deployments, 25*4882a593Smuzhiyun which are often characterized by highly dynamic endpoints and the 26*4882a593Smuzhiyun need to maintain logical abstractions for multiple tenants. 27*4882a593Smuzhiyun 28*4882a593Smuzhiyun The Open vSwitch datapath provides an in-kernel fast path for packet 29*4882a593Smuzhiyun forwarding. It is complemented by a userspace daemon, ovs-vswitchd, 30*4882a593Smuzhiyun which is able to accept configuration from a variety of sources and 31*4882a593Smuzhiyun translate it into packet processing rules. 32*4882a593Smuzhiyun 33*4882a593Smuzhiyun See http://openvswitch.org for more information and userspace 34*4882a593Smuzhiyun utilities. 35*4882a593Smuzhiyun 36*4882a593Smuzhiyun To compile this code as a module, choose M here: the module will be 37*4882a593Smuzhiyun called openvswitch. 38*4882a593Smuzhiyun 39*4882a593Smuzhiyun If unsure, say N. 40*4882a593Smuzhiyun 41*4882a593Smuzhiyunconfig OPENVSWITCH_GRE 42*4882a593Smuzhiyun tristate "Open vSwitch GRE tunneling support" 43*4882a593Smuzhiyun depends on OPENVSWITCH 44*4882a593Smuzhiyun depends on NET_IPGRE 45*4882a593Smuzhiyun default OPENVSWITCH 46*4882a593Smuzhiyun help 47*4882a593Smuzhiyun If you say Y here, then the Open vSwitch will be able create GRE 48*4882a593Smuzhiyun vport. 49*4882a593Smuzhiyun 50*4882a593Smuzhiyun Say N to exclude this support and reduce the binary size. 51*4882a593Smuzhiyun 52*4882a593Smuzhiyun If unsure, say Y. 53*4882a593Smuzhiyun 54*4882a593Smuzhiyunconfig OPENVSWITCH_VXLAN 55*4882a593Smuzhiyun tristate "Open vSwitch VXLAN tunneling support" 56*4882a593Smuzhiyun depends on OPENVSWITCH 57*4882a593Smuzhiyun depends on VXLAN 58*4882a593Smuzhiyun default OPENVSWITCH 59*4882a593Smuzhiyun help 60*4882a593Smuzhiyun If you say Y here, then the Open vSwitch will be able create vxlan vport. 61*4882a593Smuzhiyun 62*4882a593Smuzhiyun Say N to exclude this support and reduce the binary size. 63*4882a593Smuzhiyun 64*4882a593Smuzhiyun If unsure, say Y. 65*4882a593Smuzhiyun 66*4882a593Smuzhiyunconfig OPENVSWITCH_GENEVE 67*4882a593Smuzhiyun tristate "Open vSwitch Geneve tunneling support" 68*4882a593Smuzhiyun depends on OPENVSWITCH 69*4882a593Smuzhiyun depends on GENEVE 70*4882a593Smuzhiyun default OPENVSWITCH 71*4882a593Smuzhiyun help 72*4882a593Smuzhiyun If you say Y here, then the Open vSwitch will be able create geneve vport. 73*4882a593Smuzhiyun 74*4882a593Smuzhiyun Say N to exclude this support and reduce the binary size. 75
