Embodiment Construction

[0019] The technical solution of the present invention will be explained more clearly and completely through the description of preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0020] The UDP live service optimization method based on kernel forwarding of the preferred embodiment of the present invention is characterized in that, comprising:

[0021] (1) Use the dropwatch tool to grab data packets from the kernel.

[0022] Such as figure 1 The debugging method shown, #:dropwatch -l kas.

[0023] (2) Judging the system packet loss function based on the code location where the packet is lost, and adjusting the corresponding system reading configuration parameters, thereby adjusting the performance bottleneck of the system sending and receiving network reports, such as figure 2 shown.

[0024] (3) Corresponding to the position of the protocol stack, judge the layer data packet in the TCP / IP network model, thereby directly adjustin...

Abstract

The invention provides a UDP (User Datagram Protocol) live broadcast service optimization method based on kernel forwarding. The UDP live broadcast service optimization method comprises the followingsteps: capturing a data packet from a kernel by adopting a dropwatch tool; judging a system packet loss function according to the code position of the packet loss, and adjusting the corresponding system reading configuration parameters, thereby adjusting the performance bottleneck of the system for sending and receiving the network newspaper; judging the layer data packet in the TCP / IP network model according to the position of the protocol stack so as to directly adjust and repeatedly debug the related kernel parameters of the protocol layer until a large amount of drop packet information does not exist. According to the method, the bottleneck problem of the UDP online live broadcast service can be clearly displayed, kernel parameters are adjusted in a targeted mode, and the packet loss problem is solved.

Description

technical field [0001] The invention relates to the field of network live broadcast, in particular to a method for optimizing a UDP live broadcast service based on kernel forwarding. Background technique [0002] With the development of broadband access technology, data communication technology and multimedia technology, the IPTV service, which is a broadband value-added service, has developed vigorously. In the IPTV business, the live broadcast service occupies a very important position and is one of the basic services. To carry out the live broadcast service in the IP network, the IP multicast mode is generally used to copy and transmit the video stream, and its transport layer protocol is the User Datagram Protocol (UDP protocol for short). The UDP protocol does not guarantee the reliability of communication, even if a packet is lost during transmission, it cannot be recovered. [0003] In order to solve the packet loss problem, there are two methods commonly used: firs...
