Abstract: A method, apparatus, and system for implementing node port virtualization on a fiber channel in the field of communication technologies are provided. 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.

Abstract: A communications method and system. When a central control point learns that a virtual machine of a tenant is deployed on a first server, the central control point delivers, to the first server, a first local virtual local area network identifier (VLAN ID) pre-configured for the tenant, so that a virtual switch (vSwitch) of the first server stores a correspondence between the tenant and the first local VLAN ID and can control, according to the correspondence, communication between virtual machines of the tenant in a ToR switch to which the first server belongs; the central control point delivers, to a first ToR, a first mapping relationship that is between a global VLAN ID and the first local VLAN ID and is pre-configured for the tenant, so that the first ToR can control communication between virtual machines of the tenant in different servers according to the first mapping relationship.

The method includes: receiving, by a first FEF, an entire network address request message sent by a second FEF, where the entire network address request message includes an MAC address and an FC network segment of the second FEF; parsing, by the first FEF, the entire network address request message, acquiring the MAC address and the FC network segment of the second FEF, and storing the MAC address and the FC network segment of the second FEF in a routing table of the first FEF; and sending, by the first FEF, a response message to the second FEF, where the response message includes a MAC address and an FC network segment of the first FEF. Thus, distributed routing of an FCoE network is implemented, and scalability of the FCoE network is improved.
