摘要:
A method for distributing node information, including an optical node generating an information bit stream based on its own node information and distributing the information bit stream it generates and a wavelength sequence corresponding to the node information. According to various embodiments, an information bit stream is generated based on the node information of an optical node so as to reduce the volume of data in the node information distributed by an optical node.

A method, a system, and a device for processing failure is provided; the method is applicable to a label switched path (LSP) including a first node, a second node, and at least one third node. The first node and the second node are adjacent nodes suffering communication breakdown. The first node restarts. The third node is a normal node closest to the restarted first node. When the communication between the first node and the second node is broken, the third node maintains control state information of the LSP in certain time. When the communication between the first node and the second node is recovered in the certain time, the first node, the second node, and the third node recover the control state information of the LSP. A failure processing system and a device on LSP are further provided. Therefore, when several nodes on the LSP suffer communication failures, the LSP can be reliably recovered.

A resource state monitoring method, device and communication network are provided. The method includes: acquiring network event state information of a node in a network running process, detecting a data plane resource state of the node and a control plane resource state of the node when it determines that the network event state information of the node meets a resource state detection triggering condition, and reporting a detection result to a management plane of the node. The device includes an acquiring unit, a checking unit, a triggering unit, a detecting unit and a reporting unit. The network includes several nodes, a communication control device and a resource state monitoring device.

摘要:
The present invention provides a method, device and system for implementing a VPN configuration service. According to the invention, a VPN configuration request message is received at a network side and a verification is performed on the VPN configuration request message with a directory service table; and the directory service table is updated after the verification is passed; and, thus, a VPN configuration is implemented. Thus, the efficiency of the VPN service is improved. Through configuring the VPN policy information, the VPN connection request of the user is limited within a closed user group and a corresponding control is performed on the VPN connection request of the user. Thus, a flexible management mode is achieved.
