Problems solved by technology

[0005] It can be seen that since the timing call in the user state cannot achieve a high time schedule, and the call switching between business threads will also affect the accuracy of the timer, calling a system call for each data packet will cause frequent system calls , thus greatly consuming CPU resources, resulting in reduced overall system performance and overall streaming media service quality
[0006] Aiming at the problem that the streaming media file transfer method in the related technology is easy to reduce the performance of the entire system and the quality of the entire streaming media service, no effective solution has been proposed yet

Abstract

The present invention discloses a network data packet sending method and device. The method comprises: a Linux operating system kernel space receives a large network data packet sent by a user process, wherein the size of the large network data packet is larger than or equal to the size of network data packet capable of being sent by the kernel space; the kernel space splits the large network data packet into a plurality of small network data packets, wherein the size of each small network data packet is smaller than or equal to the size of network data packet capable of being sent by the kernel space; the kernel space uses a kernel space timer to send the plurality of small network data packets. The present invention reduces system CPU energy consumption and improves packet-sending performance as a whole.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and device for sending network data packets. Background technique [0002] In the application of the streaming media server based on the Linux operating system, a large number of streaming media files need to be delivered to the IP network. Streaming media packet transmission requires high stability and high time precision. Under the existing transmission mode, for each audio stream, a network socket needs to be used. After the user process packs the audio file into an RTP (Real-time Transport Protocol, Real-time Transport Protocol) packet, it calls the UDP (User Datagram Protocol, User Data Packet Protocol) data packet sending interface to send data packets out. [0003] The regular transmission of UDP data packets is realized through the timer in the user state. Due to the large number of threads in the user state and the complicated business process, it is diff...
