Abstract: A method for processing presence information is disclosed. Presence information includes different values of a presence element, classes corresponding to the values and presentity information. Authentication configuration information of a presentity is obtained according to the presentity information. A right rule is obtained by resolving the authentication configuration information. The right rule includes a correlation configured by the presentity between a watcher identity and a class of a group that the watcher identity pertains to. A value of the presence element is sent to a corresponding watcher according to a correlation between the class corresponding to the value in the presence information and the class derived from the right rule obtained from the authentication configuration information.

Abstract: The present disclosure discloses a method and apparatus for processing network protocol stack data. The method includes: extracting, from a to-be-processed data packet, an identifier used to indicate a data flow to which the to-be-processed data packet belongs; when a pre-generated rule matching table includes the identifier, processing, according to a protocol-stack layer jump processing policy that is corresponding to the identifier and that is in the rule matching table, the to-be-processed data packet on a target layer indicated by the protocol-stack layer jump processing policy. By using the method and apparatus in the present disclosure, unnecessary processing may not be performed on some data packets that do not need to be processed on all protocol-stack layers, so as to reduce or even avoid unnecessary consumption of computing resources and transmission resources.
