Multiple different virtual Node Port (N_port) identifications (IDs) are allocated to each of multiple N_ports, of an N_port virtualization (NPV) switch, corresponding to an N_port ID of a remote node. Because a virtual N_port ID is allocated, to each remote node, for more than one N_port of the NPV switch, regardless of which N_port of these N_ports a node connected to the NPV switch is registered for, the node can obtain the virtual N_port ID that is of each remote node and that is corresponding to the N_port. Therefore, any node connected to the NPV switch can communicate with any remote node, thereby improving communication efficiency.
