Overlaying virtual broadcast domains on an underlying physical network
Operations include determining that a subset of devices, from a plurality of devices, are executing a same application, located in a same geographical location, or correspond to a same user. Responsive to the determining operation, a group with the subset of devices is created and communication between the devices is supported.
1. A method, comprising:
determining that a network device is a member of two or more member virtual broadcast groups of network devices, wherein:
the member virtual broadcast groups are governed by a same group of virtual broadcast domain policies,
each network device in a virtual broadcast group of the two or more member virtual groups shares a common property, and
the common property is a property that network devices on different networks domains have in common;
utilizing a service-based policy by which the virtual broadcast group is dynamically created to include a first network device based upon use of a same network service to propagate data packets during a same time period as a second network device, without direct participation of the first and the second network devices,
wherein use of the same network service during the same time period is the common property from the service-based policy; and
transmitting a message to the first network device that shares the common property and withholding transmission of the message to another network device of the two or more member virtual broadcast groups of network devices that is without the common property.
2. The method of claim 1 , wherein transmitting further comprises transmitting a broadcast message to the network device that shares the common property.
3. The method of claim 1 , further comprising deriving the common property from a broadcast group membership policy.
4. The method of claim 3 , wherein the broadcast membership policy further includes a user-based policy, and the method further comprises deriving the common property from the user-based policy.
5. The method of claim 3 , wherein the broadcast membership policy further includes a role-based policy, and the method further comprises deriving the common property from the role-based policy.
6. The method of claim 3 , wherein the broadcast membership policy further includes a location-based policy, and the method further comprises deriving the common property from the location-based policy.
7. The method of claim 3 , wherein the broadcast membership policy further includes an application-based policy, and the method further comprises deriving the common property from the application-based policy.
8. A network control device, comprising:
a processor; and
a memory having instructions stored thereon, which when executed by the processor, cause the computing device to:
determine that a network device is a member of two or more member virtual broadcast groups of network devices, wherein:
the member virtual broadcast groups are governed by a same group of virtual broadcast domain policies,
each network device in a first virtual broadcast group of the two or more member virtual broadcast groups shares a common property, and
the common property is a property that network devices on different network domains have in common;
utilize a service-based policy by which the first virtual broadcast group is dynamically created to include a first network device based upon use of a same network service to propagate data packets during a same time period as a second network device, without direct participation of the first and the second network devices, and
wherein use of the same network service during the same time period is the common property from the service-based policy; and
transmit a message only to network devices that share the common property and withhold transmission of the message is to another network device of the two or more member virtual broadcast groups of network devices that is without the common property.
9. The computing device of claim 8 , wherein the network control device is a network controller.
10. The computing device of claim 8 , wherein the network control device is a router.
11. The computing device of claim 8 , wherein the network control device is an access point.
12. The computing device of claim 8 , wherein the network devices are client devices.
13. A non-transitory computer readable medium comprising instructions which, when executed, causes a processor to:
determine a common property among network devices, wherein the common property is a property that network devices on different layer 2 network domains have in common;
determine that a network device is a member of two or more member virtual groups of network devices, wherein:
the member virtual broadcast groups are governed by a same group of virtual broadcast domain policies, and
each network device in a virtual broadcast group of the two or more member virtual groups shares the common property;
utilize a service-based policy by which the virtual broadcast group is dynamically created to include a first network device based upon use of a same network service to propagate data packets during a same time period as a second network device, without direct participation of the first and the second network devices, and
wherein use of the same network service during the same time period is the common property from the service-based policy; and
transmit a broadcast message only to network devices that share the common property and withhold transmission of the broadcast message to another network device in another member virtual broadcast group of the two or more member virtual broadcast groups of network devices that is without the common property.
14. The medium of claim 13 , further comprising instructions to:
determine that a network device in a virtual member group of the two or more member virtual groups ceases to share the common property with the other network devices of the virtual group; and
dynamically update the virtual group in response to the determination that the network device ceases to share the common property.
15. The method of claim 1 , wherein the different network domains comprise different network broadcast domains.
16. The network control device of claim 8 , wherein the different network domains comprise different network broadcast domains.
17. The medium of claim 13 , wherein the different network domains comprise different network broadcast domains.
