Title: NODE SWITCHING METHOD, DEVICE, AND SYSTEM
Abstract:
A node switching method, a device, and a system are disclosed, belonging to the field of communication technology. The method comprises: receiving a protocol configuration request message sent by a target access node, the protocol configuration request message including Quality of Service (QoS) parameters of a UE service; according to the QoS parameters, determining the functional module that the UE service corresponds to; according to the network topology and the functional module that the UE service corresponds to, configuring the functional module for a target node; according to the network topology and the functional module configured for the target node, determining a first set of forwarding table entries required for data stream transmission between a source node and any one of the target nodes; according to the network topology and the functional module configured for the target node, determining a second set of forwarding table entries required for data stream transmission between any one of the target nodes and a gateway. The present invention solves the problem of the function of an SDP network system being relatively simple, achieving the effect of enriching the functions of the SDP network system. The present invention is used in node switching.
