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

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.
