Abstract: The present invention discloses a data stream distribution method and apparatus. In the method, a load balancer may access data in a data stream according to an instruction in a distribution rule that is sent by an application server according to an interface protocol or configured on the load balancer according to an interface protocol; determine, according to a keyword generated according to the accessed data, an application server that processes the data stream; and send the data stream to the determined application server. Therefore, the load balancer may access the data in the data stream according to an instruction in a common distribution rule, to distribute the data stream, thereby reducing complexity of data stream distribution performed by the load balancer.

Abstract: This application discloses a disaster recovery deployment method, apparatus, and system, and relates to the field of network application technologies. The method includes: obtaining, by a master data center and a backup data center, disaster recovery control information; sending, by the master data center, the data corresponding to the service of the master data center to the at least one backup data center based on the disaster recovery control information; and deploying, by the backup data center, a disaster recovery resource for the master data center based on the disaster recovery control information, and backing up the received data. In other words, the master data center and the backup data center automatically back up resources and data based on the disaster recovery control information, and therefore, manual operation steps in a disaster recovery deployment process are simplified, and efficiency of disaster recovery deployment is improved.

Abstract: This embodiment provides a user packet forwarding control method and a processing node. A processing node receives a processed user packet sent by a first target value-added server (VAS), and the processing node correspondingly generates a target processing identifier according to the processed user packet, so that the processing node determines, according to the target processing identifier, that the user packet has been processed by the first target VAS. Each processing node can determine VASs that have processed the user packet, without the need to change the original user packet, thereby effectively ensuring that each VAS provides a normal value-added service to the user packet, and avoiding a fault in a process of forwarding the user packet between value-added servers.
