Abstract: A method for determining a network optimization policy, an apparatus, and a system are provided. A network optimization device can process a performance parameter of a network and a service requirement of a target service flow by using a network optimization algorithm, to obtain a target network optimization policy, and can apply the target network optimization policy to the target service flow, to enable transmission performance of the target service flow to satisfy the service requirement. Because the network optimization device can automatically determine the network optimization policy based on the network optimization algorithm, efficiency of determining the network optimization policy is effectively improved. In addition, when determining the network optimization policy, the network optimization device further considers the performance parameter of the network.

Abstract: A packet processing method and system, and a network device are disclosed, and belong to the field of network technologies. A first network device sends a first packet to a second network device through a first tunnel, and sends a second packet to a third network device through a second tunnel. The second network device forwards the first packet to the third network device through a third tunnel. The third network device processes the first packet and the second packet. The first network device is located at a first site. The second network device and the third network device are located at a second site. The first site and the second site are connected through a wide area network. Wide area network multipath transmission may be implemented in a multi-gateway scenario.

Abstract: A media stream sending method, apparatus, and system includes a proxy server that receives a first live broadcast room request message and a second live broadcast room request message that are sent by a same proxy client; the proxy server receives a first live media stream that is sent by a media server to a first client and a second live media stream that is sent by the media server to a second client; and when a role of the first client is a master user and a role of the second client is a slave user, the proxy server sends the first live media stream to the proxy client such that the proxy client sends the first live media stream to the first client and the second client.

Abstract: Embodiments of this application disclose a chunking method and an apparatus for implementing the method. According to the method provided in the embodiments of this application, a first data segment of a first length may be determined starting from a header of a to-be-chunked data flow, a data distribution characteristic of the first data segment is determined based on character values of all characters in the first data segment, and then a chunking position is determined for different data distribution characteristics by using different methods. In this way, a data flow can be better chunked, so as to enhance a deduplication effect.
