A peer enrollment method, a route updating method, a communication system, and relevant devices to improve security of a peer-to-peer (P2P) network are provided. 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.

Route updating method, communication system, and relevant devices

Methods, devices, and systems for registering and discovering a service. An access point (AP) may receive and maintain service information registered by an associated station (STA), and serve as a proxy for a STA to discover service information in a network, and further discover a direct association service and manage direct communication between STAs, thereby meeting a user's demand of selecting a network according to a service requirement.

The present invention discloses a method and an apparatus for configuring a network policy of a virtual network. The method includes: receiving, by a server, a network policy message sent by a virtual machine management center and used for creating a virtual network, where the network policy message for creating a virtual network includes a virtual network identification (VNID) of a virtual network to be created and network policy configuration information corresponding to the virtual network to be created; and sending, by the server, a network policy synchronization message to a network device, where the network policy synchronization message includes the VNID of the virtual network to be created and the network policy configuration information corresponding to the virtual network to be created. Consequently, processing overheads can be reduced.

Method and apparatus for configuring network policy of virtual network

The present invention provides a method and an apparatus for migrating virtual machine parameters and a virtual machine server. The method includes receiving a virtual machine parameter migration message at a not-running stage of a virtual machine, where the virtual machine parameter migration message is used to cause an upstream network device of the virtual machine to migrate virtual machine parameters of the virtual machine at the not-running stage of the virtual machine, and the virtual machine parameter migration message includes an identifier of the virtual machine. The present invention may implement migration of the virtual machine parameters correctly and solve a service interruption problem in virtual machine migration.

Method, migration management apparatus, network device, and virtual machine server for migrating virtual machine parameters

A method, an apparatus, and a system for network address translation related to the field of communications technologies. A NAT control apparatus receives a network address migration message after a first data center migrates a NAT mapping entry corresponding to a migrated virtual machine VM to a second data center, verifies the network address migration message, and updates home information of the NAT mapping entry in a network address mapping table from the first data center to the second data center according to the network address migration message. In this way, NAT address resources in each data center can be properly planned, and a release attack problem caused by a fact that applying and using of a VM are not performed in a same data center can be solved.

Method, apparatus, and system for network address translation

A method implemented by a network component is provided. The method includes receiving a Virtual Station Interface (VSI) Discovery Protocol (VDP) request from an Edge Virtual Bridging (EVB) station and transmitting, to the EVB station, a VDP Response in response to the request. The VDP Response includes a VDP Type-Length-Value (TLV) having a Filter Information field. The Filter Information field is configured to specify a Priority Code Point (PCP) value associated with one or more Virtual Local Area Network (VLAN) Identifier (VID) values carried by the VDP Response. The PCP value is carried in a PCP field and adopted by the EVB station as a default PCP value associated with the VSI and at least one VID. The Filter Information field further contains a PCP Significant (PS) field associated with each PCP field, and wherein the PS field indicates whether the PCP field carries the PCP value.

Specifying priority on a virtual station interface discovery and configuration protocol response

An apparatus comprising an Edge Virtual Bridging (EVB) bridge coupled with an EVB station wherein the EVB bridge is configured to communicate to the EVB station a Filter Information (Info) field of a virtual station interface (VSI) discovery and configuration protocol (VDP) Associate Response message, and wherein the Filter Info field specifies a default Priority Code Point (PCP) value associated with at least one or all of a plurality of VID values carried by that VDP TLV Response.

Embodiments of the present invention disclose 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.
