Abstract: A method and a device for directing traffic are provided. The method includes: determining whether a tag of a to-be-sent data packet is same as a reference tag configured in a preset matching rule; under situations where a determination result is that tag of the to-be-sent data packet is not the same as the reference tag configured in the preset matching rule, configuring the to-be-sent data packet with the reference tag by redirecting the to-be-sent data packet; sending the to-be-sent data packet configured with the reference tag.

Abstract: A data packet transmission method is provided, including: receiving, by a proxy program, a request data packet via a listening port of the proxy program, and after marking the request data packet, sending out, by the proxy program, the marked request data packet; receiving, by a local system, a plurality of request data packets sent by an application program or the proxy program, and matching, by the local system, a mark in the request data packet. When the matching is successful, the request data packet is forwarded out directly, and when the matching is unsuccessful, the request data packet is re-directed to the listening port. Further, a data packet transmission system is provided.

Abstract: A UDP protocol acceleration system includes a client terminal, an acceleration server, and a source station. The client terminal includes a local proxy at the application layer and one or more local applications to be accelerated, and a network filter at the IP layer. The local proxy identifies redirection requests from different local applications among requests received and, for each redirection request, queries an original destination address, and encapsulates and sends the original destination address and the redirection request to the acceleration server. The acceleration server parses the original destination, acts as a proxy for the redirection request, and sends a response back to the local proxy. The local proxy, after receiving the response from the acceleration server, queries acceleration records, and forwards the response to a corresponding local application.

Abstract: A method for managing traffic of application programs includes: reading attribute information of a data packet sent by an application program, where the attribute information indicates a source of the data packet; based on the attribute information of the data packet, determining whether the application program that sends the data packet is a designated broadcasting tool, thereby differentially managing a data packet from the designated broadcasting tool and a data packet not from the designated broadcasting tool.
