Transfer of secure multicast data traffic over a computing network
Disclosed herein are systems and methods for scalable and secure transmission of multicast data over a public communication network. In exemplary embodiments of the present disclosure, a virtual overlay network can be presented as a single virtual interface to a computing device, for the receipt and transfer of multicast data in a secure and scalable manner across a public insecure communication network.
1. A method for transmitting multicast data over a public communication network by a first network appliance, the method comprising:
receiving at the first network appliance, designated as a rendezvous point for a multicast data transmission, a request from a second network appliance to receive the multicast data transmission;
determining that the second network appliance receives the multicast data transmission based on a multicast-compliant routing protocol associated with the request;
transmitting the multicast data transmission from a transmitting computing device to a virtual interface of the first network appliance;
encapsulating the multicast data transmission by the first network appliance into a virtual network overlay transmission;
transmitting the virtual network overlay transmission from the first network appliance over the public communication network to the second network appliance; and
transmitting the multicast data transmission by the second network appliance to a receiving computing device.
2. The method of claim 1 , wherein the second network appliance further duplicates the multicast data transmission and transmits to a plurality of receiving computing devices.
3. The method of claim 1 , wherein the receiving computing device requests to receive the multicast data transmission via an IGMP join message.
4. The method of claim 1 , wherein the second network appliance requests to receive the multicast data transmission from the first network appliance via a PIM-SM message.
5. The method of claim 1 , wherein the first network appliance and the second network appliance are connected via a virtual overlay network overlaying the public communication network.
6. The method of claim 1 , wherein the first network appliance and the second network appliance are in communication with an orchestrator device over a virtual overlay network overlaying the public communication network.
7. The method of claim 6 , wherein the orchestrator device is further configured to create one or more virtual paths in the virtual overlay network automatically.
8. The method of claim 1 , wherein the first network appliance and the second network appliance are located in disparate geographical locations.
9. A first network appliance, comprising:
a processor; and
a memory operatively connected to the processor, and including instructions that when executed, cause the processor to:
receive at the first network appliance, designated as a rendezvous point for a multicast data transmission, a request from a second network appliance to receive the multicast data transmission;
determine that the second network appliance receives the multicast data transmission based on a multicast-compliant routing protocol associated with the request;
transmit the multicast data transmission from a transmitting computing device to a virtual interface of the first network appliance;
encapsulate the multicast data transmission by the first network appliance into a virtual network overlay transmission;
transmit the virtual network overlay transmission from the first network appliance over the public communication network to the second network appliance; and
transmit the multicast data transmission by the second network appliance to a receiving computing device.
10. The first network appliance of claim 9 , wherein the second network appliance further duplicates the multicast data transmission and transmits to a plurality of receiving computing devices.
11. The first network appliance of claim 9 , wherein the receiving computing device requests to receive the multicast data transmission via an IGMP join message.
12. The first network appliance of claim 9 , wherein the second network appliance requests to receive the multicast data transmission from the first network appliance via a PIM-SM message.
13. The first network appliance of claim 9 , wherein the first network appliance and the second network appliance are connected via a virtual overlay network overlaying the public communication network.
14. The first network appliance of claim 9 , wherein the first network appliance and the second network appliance are in communication with an orchestrator device over a virtual overlay network overlaying the public communication network.
15. The first network appliance of claim 14 , wherein the orchestrator device is further configured to create one or more virtual paths in the virtual overlay network automatically.
16. The first network appliance of claim 9 , wherein the first network appliance and the second network appliance are located in disparate geographical locations.
17. A network appliance, comprising:
a memory; and
one or more processors configured that are configured to execute machine readable instructions stored in the memory to:
receive at the network appliance, designated as a rendezvous point for a multicast data transmission, a request from another network appliance to receive the multicast data transmission;
determine that the second network appliance receives the multicast data transmission based on a multicast-compliant routing protocol associated with the request;
transmit the multicast data transmission from a transmitting computing device to a virtual interface of the network appliance;
encapsulate the multicast data transmission by the network appliance into a virtual network overlay transmission;
transmit the virtual network overlay transmission from the network appliance over a public communication network to the other network appliance; and
transmit the multicast data transmission by the other network appliance to a receiving computing device.
18. The network appliance of claim 17 , wherein the network appliance and the other network appliance are connected via a virtual overlay network overlaying the public communication network.
19. The network appliance of claim 17 , wherein the network appliance and the network appliance are in communication with an orchestrator device over a virtual overlay network overlaying the public communication network.
20. The network appliance of claim 17 , wherein the first network appliance and the other network appliance are located in disparate geographical locations.
