The invention discloses an MQTT server failover method, architecture, equipment and medium, a master node and a slave node communicate through a virtual routing redundancy (VRRP) protocol, and the master node periodically sends a VRRP heartbeat message to the slave node; when a host-level fault occurs and the slave node does not receive a VRRP heartbeat message of the master node within a preset timeout interval, the slave node takes over a virtual IP address and is upgraded to a master role; when a service-level fault occurs, the detection program running on the main node detects that the specified service is abnormal, and the main node actively reduces the priority of the main node and cancels the virtual IP address bound with the main node; and when detecting that the priority of the master node is lower than that of the slave node, the slave node immediately initiates election and becomes a new master node, and binds the virtual IP address to complete fault switching. By detecting the host-level fault and the service-level fault respectively, compared with single-point deployment, when the server fails, services can be continuously provided to the outside, and the continuity of services is ensured.

This invention provides a method, system, device, and medium for underwater multimodal hybrid cross-layer opportunistic transmission, enabling end-to-end differentiated transmission of multiple services under multiple heterogeneous transmission modes underwater. The method achieves accurate evaluation of the forwarding performance of heterogeneous transmission modes through an initial set of candidate relay nodes and a method for selecting the optimal candidate relay region.

To address the limitations of underwater resource-poor network environments, a reward update method with state-action space traversal is adopted, enabling nodes to simultaneously calculate simulated rewards corresponding to different service types and routing parameters based on feedback from a single service transmission, while simultaneously calculating rewards for actual actions.
