Abstract: The application provides a route synchronization method and an apparatus. 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.

Abstract: A peer enrollment method, a route updating method, a communication system, and relevant devices to improve security of a peer-to-peer (P2P) network. The peer enrollment method includes: receiving an enrollment request from a peer, where the enrollment request carries identity information of the peer; verifying the identity information of the peer, and if the verification succeeds, obtaining peer location information of the peer and generating a peer credential according to the peer location information; and sending the peer credential carrying the peer location information to the peer so that the peer joins the P2P network according to the peer credential. Embodiments of the present application further provide a route updating method, a communication system, and relevant devices. Embodiments of the present application may improve security of the P2P network effectively.

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.
