Abstract: A method for realizing an Internet protocol (IP) multimedia subsystem (IMS) disaster tolerance includes the steps as follows. An S-CSCF receives a user registration, and backs up necessary data which is required when a user service processing is restored on a storage entity in a network. An I-CSCF of user's home domain receives a service request of the user, and if it is found that the S-CSCF currently providing a service for the user fails, assigns a new S-CSCF to the user, and forwards the service request to the newly assigned S-CSCF. The newly assigned S-CSCF interrogates and acquires subscription data of the user and the necessary data backed up by the original S-CSCF from the storage entity, and then restores the user service processing according to the subscription data and the backup data. A device for realizing an IMS disaster tolerance is also provided.

Abstract: A method for analyzing a network transmission characteristic, includes: receiving, by an intermediate network element, a service packet sent by a first service network element through the intermediate network element to a second service network element, where the service packet carries a service stream identifier, service stream information, and a control rule, where the service stream identifier is used to identify a service stream, the service stream information is used to provide a parameter that is required during transmission characteristic analysis, and the control rule is used to determine a type of the transmission characteristic analysis; and determining, by the intermediate network element, the type of the transmission characteristic analysis according to the received control rule, and performing, according to the service stream information, the transmission characteristic analysis on the service stream identified by the service stream identifier in a network application.

Abstract: A method, a device and a system for evaluating network reliability are disclosed in the embodiments of the present invention. The method includes: determining an analysis object by acquiring network topology information; acquiring a network failure mode of the analysis object; and analyzing and evaluating reliability of the analysis object in a hierarchical and overall way with respect to the failure mode. As the concept of a hierarchical analysis is introduced into the analysis, analysis properties of analysis objects (for example, a node and a connection) are divided according to hierarchies, so that the network is effectively decomposed, an overall decomposing analysis is ensured, and the difficulty of the analysis is reduced.
