摘要： A method, apparatus and system for processing of a series of service messages. In one embodiment, the series of service messages is formed by a plurality of service messages, and at least two server instances provide real-time processing of the service messages and store the information provided by the service messages and results obtained from processing the service messages. The method includes the steps of: determining an activity that affects real-time processing of the service messages will occur in at least one server instance of the server instances; and dispatching subsequent service messages among the service messages to other server instance(s) other than the at least one server instance, so as to ensure that said activity will not affect message processing delay.

摘要： A method for rejecting received SIP messages which are redundantly retransmitted used in a Session Initiation Protocol (SIP) application architecture. In one embodiment, the method comprises: forwarding all the messages transmitted from a SIP application server to a SIP terminal, and dropping all the received SIP messages redundantly retransmitted from the SIP terminal to the SIP application server according to the transmission direction of said SIP messages; and correspondingly replying to the dropped SIP messages according to the message type thereof. The present invention also provides a corresponding retransmission rejection device and a network device comprising the same, and further provides a method and device for rapidly rejecting redundantly retransmitted SIP messages in the case where the memory space is limited. The present invention can be applied to a network device such as a SIP stateless proxy at a front end of a SIP application server cluster.

摘要： A method and system for garbage collection in a virtualization environment. The virtualization environment includes a virtual machine hypervisor, at least one guest operating system, and at least one application program that runs on each guest operating system. The application program performs memory management using a garbage collection mechanism. The method includes, in response to an operating environment of the application program initiating garbage collection, the garbage collector requesting the guest operating system to assign a memory space and in response, the guest operating system assigns the memory space to the garbage collector. Then garbage collector marks live objects in an original memory space of the application program, and replicates the marked live objects to the assigned memory space. Finally, the garbage collector releases the original memory space of the application program to the guest operating system.

摘要： A method and apparatus for protecting user information. The method includes receiving a request for accessing the user information from an application. When the request does not include an authorized token, the user is requested to temporally confirm the request for access. In response to the confirmation, a token is generated and the user on a mobile service platform is associated with the request for access by the token. The application is then allowed to access the user information based on the token associating the user with the request for accessing the user information from the application.
