HTTP-based message broker architectures for communications between a cloud-based controller and network devices of a wireless communications network and related methods

1 . A method for a cloud-based controller to communicate with a network device of a wireless communications network, the method comprising:

forwarding a message from an application of the cloud-based controller to a message broker of the cloud-based controller;

translating the message into a translated message suitable for transmission to the network device;

transmitting, from the cloud-based controller, the translated message to the network device over a WebSocket tunnel; and

receiving an acknowledgment in response to transmitting the translated message at a gRPC proxy for the message broker, wherein the cloud-based controller comprises the gRPC proxy,

wherein the message broker is configured to receive additional messages from a plurality of different applications of the cloud-based controller, and

wherein the message broker includes a plurality of queues, and the message and the additional messages are routed to queues of the message broker based on destination addresses of the message and the additional messages.

2 . The method of claim 1 , further comprising forwarding the message to a WebSocket server prior to transmitting the message to the network device.

3 . The method of claim 1 , wherein the message and the additional messages are all routed to the network device through the WebSocket tunnel.

4 . The method of claim 1 , wherein the message is received at a WebSocket client of the network device and then forwarded to a message broker client library of the network device.

5 . The method of claim 1 , wherein the message broker comprises a fire and forget message broker.

6 . The method of claim 1 , wherein the acknowledgment is received at the message broker and passed to the application of the cloud-based controller.

7 . The method of claim 1 , wherein the acknowledgment is received at an ingress controller of the cloud-based controller and passed directly to the application of the cloud-based controller.

8 . The method of claim 1 , wherein the acknowledgment includes an address of the application of the cloud-based controller.

9 . A method of controlling a network device of a wireless communications network, the method comprising:

forwarding messages from a plurality of services of a cloud-based controller to the network device over a single, WebSocket tunnel between the cloud-based controller and the network device,

wherein a message broker of the cloud-based controller includes a plurality of queues, and the messages are routed to the queues of the message broker based on destination addresses of the messages, prior to forwarding to the network device.

10 . The method of claim 9 , wherein the messages are forwarded from the services to the message broker of the cloud-based controller prior to being transmitted over the single, WebSocket tunnel between the cloud-based controller and the network device.

11 . The method of claim 10 , wherein the messages are forwarded from the message broker of the cloud-based controller to a gRPC proxy of the cloud-based controller prior to being transmitted over the single, WebSocket tunnel between the cloud-based controller and the network device.

12 . The method of claim 11 , further comprising receiving an acknowledgment in response to a first of the messages at the gRPC proxy of the cloud-based controller.

13 . The method of claim 12 , further comprising forwarding the first of the messages to the gRPC proxy for the message broker prior to transmitting the first of the messages to the network device.

14 . The method of claim 9 , wherein the message broker comprises a fire and forget message broker.
