Problems solved by technology

[0005] In the existing technical solution, when controlling the video stream, the forwarding of the video stream is mostly realized according to the multicast forwarding table, and the limitation of the terminal is placed on each air interface. The basic flow chart is as follows Figure 5 As shown, this function is divided into two parts, one part is placed in the kernel to learn the multicast table, and the other part is to record terminal information in the SDK. The above solution is implemented in the kernel, and the disadvantages are as follows: (1) The current function does not support multicast sources The control of the number and multicast address, the control of the multicast source needs to increase the kernel interface, which may destroy the system stability
(2) The limit on the number of multicast to unicast is only valid on one air interface, and there is no global limit

Embodiment 1

[0047] The embodiment of the present invention mainly relates to a method for realizing wireless access device to control video stream, monitor and intercept the IGMP (Internet Group Management Protocol, Internet Group Management Protocol) data packet sent by the terminal on the wireless access device, and configure the ebtables rule Formally restricts video streams to achieve the purpose of restricting multicast sources and limiting the number of terminals receiving video streams by combining multicast to unicast time air interface to record terminal information.

[0048] Internet Group Management Protocol (IGMP) is a protocol responsible for IP multicast member management in the TCP / IP protocol suite, and is used to establish and maintain multicast group membership between an IP host and its directly adjacent multicast routers.

[0049] Ebtables is the Ethernet bridge firewall, the Ethernet bridge works at the data link layer, and ebtables filters the data link layer data pac...

Embodiment 2

[0090] Figure 4 It is a structural diagram of a system for realizing wireless access equipment to control video streams in this embodiment, as shown in Figure 4 As shown, in this embodiment, a system for realizing wireless access device control of video stream includes:

[0091] The receiving module 10 is used to receive the Internet group management protocol data packet sent by the terminal, and the data packet includes: the port information of the terminal and the multicast source address information of the video stream;

[0092] The first judging module 20 is configured to judge whether the multicast source is allowed to multicast according to the address information of the multicast source;

[0093] The second judging module 30 is used to judge whether the current number of multicast terminals of the multicast source is lower than the maximum number of multicast terminals;

[0094] The third judging module 40 is used for judging whether the port already exists.

Abstract

The invention discloses a method and a system for a wireless access device to control video streams. The method comprises the following steps of S1.receiving an Internet group management protocol data packet sent by a terminal; S2.judging whether multicast of a multicast source is allowed according to multicast source address information, if yes, executing the next step; S3.judging whether the number of the current multicast terminals of the multicast source is lower than the maximum number of the multicast terminals, if yes, executing the next step; and 4.judging whether a port exists, if no, creating a corresponding table of the multicast source and the port and recording port information. According to the embodiments of the invention, the video streams can be limited according to the forwarding performance supported by the wireless access device, so that the playing fluency of a terminal video is guaranteed; in addition, the video streams can be limited through an ebtables rule, the dependence on the support of a switch chip and the increase of a kernel configuration interface are not needed, and the configurability is strong.

Description

technical field [0001] The present invention relates to the technical field of video stream control, in particular to a method and system for realizing wireless access device control of video stream. Background technique [0002] With the development of Internet technology and intelligent mobile terminal equipment, various Internet products have brought a lot of convenience and entertainment to people's work and life. Since the existing wireless WiFi communication system generally can only accommodate video data transmission of limited users at the same time, Therefore, in the process of data transmission, there is often a problem of multi-user competition for channels, which makes it impossible to meet the transmission of multi-user high-definition video data streams. With the increasing demand of mass consumption, this simply cannot meet the demands of multi-user multi-program transmission and playback of high-definition video at the same time. [0003] For example, the "...
