Abstract

The invention provides a packet receiving method, device and system for a network media stream. The method comprises the steps of receiving an instruction for acquiring data packets at a user side, wherein the instruction comprises the preset packet receiving number; and sending the preset packet receiving number of data packets to a user receiving buffer at the user side after the preset packet receiving number of data packets are acquired from a core receiving buffer in a core space. The problem that the performance of a stream media server is severely degraded due to the fact that the system frequently calls network data packets is solved, thereby improving the outgoing service capability of the stream media server.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method, device and system for receiving network media stream packets. Background technique [0002] In operating systems such as Unix / Linux, network packets are generally received through network sockets using system calls. In the process of receiving data packets, it is necessary to fall into the kernel state through relevant system calls, and copy the data packets received by the network card from the kernel receiving buffer to the user buffer. For the User Data Protocol (UDP) code stream, the system call recvfrom for receiving packets can only return one packet at a time. [0003] In related technologies, an Internet Protocol Television (IPTV for short) streaming server may need to receive live code streams of more than two hundred channels from an encoder. Calculated on the basis of 200 channels with a code rate of 8Mbps for each channel, the traffic to be received will...
