In addition to supporting a variety of features 2362306a36Sopenharmony_ci expected in a traditional hardware switch, it enables fine-grained 2462306a36Sopenharmony_ci programmatic extension and flow-based control of the network. This 2562306a36Sopenharmony_ci control is useful in a wide variety of applications but is 2662306a36Sopenharmony_ci particularly important in multi-server virtualization deployments, 2762306a36Sopenharmony_ci which are often characterized by highly dynamic endpoints and the 2862306a36Sopenharmony_ci need to maintain logical abstractions for multiple tenants. 2962306a36Sopenharmony_ci 3062306a36Sopenharmony_ci The Open vSwitch datapath provides an in-kernel fast path for packet 3162306a36Sopenharmony_ci forwarding. It is complemented by a userspace daemon, ovs-vswitchd, 3262306a36Sopenharmony_ci which is able to accept configuration from a variety of sources and 3362306a36Sopenharmony_ci translate it into packet processing rules. 3462306a36Sopenharmony_ci 3562306a36Sopenharmony_ci See http://openvswitch.org for more information and userspace 3662306a36Sopenharmony_ci utilities. 3762306a36Sopenharmony_ci 3862306a36Sopenharmony_ci To compile this code as a module, choose M here: the module will be 3962306a36Sopenharmony_ci called openvswitch. 4062306a36Sopenharmony_ci 4162306a36Sopenharmony_ci If unsure, say N. 4262306a36Sopenharmony_ci 4362306a36Sopenharmony_ciconfig OPENVSWITCH_GRE 4462306a36Sopenharmony_ci tristate "Open vSwitch GRE tunneling support" 4562306a36Sopenharmony_ci depends on OPENVSWITCH 4662306a36Sopenharmony_ci depends on NET_IPGRE 4762306a36Sopenharmony_ci default OPENVSWITCH 4862306a36Sopenharmony_ci help 4962306a36Sopenharmony_ci If you say Y here, then the Open vSwitch will be able create GRE 5062306a36Sopenharmony_ci vport. 5162306a36Sopenharmony_ci 5262306a36Sopenharmony_ci Say N to exclude this support and reduce the binary size. 5362306a36Sopenharmony_ci 5462306a36Sopenharmony_ci If unsure, say Y. 5562306a36Sopenharmony_ci 5662306a36Sopenharmony_ciconfig OPENVSWITCH_VXLAN 5762306a36Sopenharmony_ci tristate "Open vSwitch VXLAN tunneling support" 5862306a36Sopenharmony_ci depends on OPENVSWITCH 5962306a36Sopenharmony_ci depends on VXLAN 6062306a36Sopenharmony_ci default OPENVSWITCH 6162306a36Sopenharmony_ci help 6262306a36Sopenharmony_ci If you say Y here, then the Open vSwitch will be able create vxlan vport. 6362306a36Sopenharmony_ci 6462306a36Sopenharmony_ci Say N to exclude this support and reduce the binary size. 6562306a36Sopenharmony_ci 6662306a36Sopenharmony_ci If unsure, say Y. 6762306a36Sopenharmony_ci 6862306a36Sopenharmony_ciconfig OPENVSWITCH_GENEVE 6962306a36Sopenharmony_ci tristate "Open vSwitch Geneve tunneling support" 7062306a36Sopenharmony_ci depends on OPENVSWITCH 7162306a36Sopenharmony_ci depends on GENEVE 7262306a36Sopenharmony_ci default OPENVSWITCH 7362306a36Sopenharmony_ci help 7462306a36Sopenharmony_ci If you say Y here, then the Open vSwitch will be able create geneve vport. 7562306a36Sopenharmony_ci 7662306a36Sopenharmony_ci Say N to exclude this support and reduce the binary size. 77
