RESOURCE RELEASE METHOD, SYSTEM, AND DEVICE, AND COMPUTER STORAGE MEDIUM

Abstract(summary):

The present invention relates to a resource release method, system, and device, and computer storage medium in a service function chain. The method comprises: a classifier constructs, upon detection of a flow being in a termination state, a flow release message packet carrying a flow release identifier and link information of the flow; the classifier sends, according to the link information, to a corresponding service function forwarder the flow release message packet; the service function forwarder forwards, according to the link information, to a corresponding function node the flow release message packet; and upon receiving the flow release message packet, the function node releases, according to the flow release identifier carried in the flow release message packet, a corresponding resource.
