Abstract

The embodiment of the application provides a functional addressing routing method, a device and gateway equipment, wherein the method comprises the steps of receiving a functional addressing request, and determining request information corresponding to the functional addressing request, a target node and a shared queue; and transmitting the request information in the isolation layer to the target node based on the special queue corresponding to the target node. By adding the isolating layer, after the isolating layer receives the function addressing request, the shared queue is actively released, so that the resource can be reused without waiting for the processing result of the target node, and the problem of functional addressing route blocking caused by unreleased shared queue is solved.
