Problems solved by technology

[0013] (1) The processing power of the user equipment is limited
Since the main control board of the access device needs to process all the IGMP messages on the user side and the control messages sent to the network side, and when multiple users join a program source at the same time, the access device needs to process each user's IGMP request All packets are processed, and there is a lot of repetitive processing work. When a large number of users switch video service channels, the performance of the access device will not be able to handle it
[0014] (2) The processing and data delivery of edge devices requires a certain delay, which affects the switching speed of user programs and deteriorates customer experience
Obviously, this is unacceptable in practical applications
[0017] (2) If the access device adopts the tree-type distributed forwarding method, since it is impossible to push all the multicast traffic to the interface board within the entire system, this technical solution is not suitable for the tree-type distributed forwarding method Access equipment, poor network compatibility
[0018] In short, this technical solution has poor implementability and is not suitable for implementation and application

Embodiment 1

[0083] In this embodiment, the method of the present invention is illustrated by taking the processing of multicast inside the access device as an example.

[0084] Fig. 4 is the schematic flow chart of the method of this embodiment, as shown in the figure, this method comprises the following steps:

[0085] Step S401: Obtain the user's frequently used multicast channel.

[0086] Periodically record the multicast groups maintained by multicast and the time points when users join and leave each multicast group according to the multicast processing information received by each interface board and submitted to the multicast processing unit of the main control board for processing records, and collect statistics The frequency and time distribution of the program on-demand in each interface board, and the statistical results are further counted to obtain the distribution of channels in each time period in a relatively long period of time in the access device. Obtain the program fr...

Embodiment 2

[0113] In this embodiment, the method of the present invention is illustrated by taking the multicast processing inside the access device as an example.

[0114] In order to optimize the multicast processing inside the access device, an interface board multicast processing unit for multicast processing (such as the interface board multicast processing unit 313 shown in FIG. 7 ) is added in the interface board.

[0115] Fig. 5 is the method flowchart of this embodiment, as shown in the figure, this method comprises the following steps:

[0116] Step S501: Obtain the user's frequently used multicast channel.

[0117] This step is the same as step S401 in embodiment 1, the difference is that, because the interface board multicast processing unit for processing the user IGMP message received by the interface board is added in the access board, therefore The acquisition of the multicast channels commonly used by users is based on the multicast groups maintained by multicast record...

Embodiment 3

[0148] In Embodiment 2, an intelligent decision-making solution is used to count frequently-used channels inside the access device and push the counted frequently-used channels to corresponding interface boards. By the extension of the method in embodiment 2, the solution is applied to the multicast processing of the access network, specifically as follows:

[0149] In each access network within the access network, according to the time points when users in each interface board in each access device join and leave each multicast channel, collect statistics on the program-on-demand frequency and time in each interface board The statistical results of all interface boards in all access devices are further aggregated and statistically analyzed to obtain the commonly used channels in the access network, and the user's commonly used multicast channel order frequency or frequency weight is higher, or the use time Long access devices. The statistical method is the same as step S501 ...

Abstract

The invention relates to a method for treating multicast and relative system. Wherein, it uses intelligent decision, adds intelligent decider in multicast processing system, uses accumulation method to obtain the common multicast channel, to actively make the access device obtain the multicast flow of common multicast channel, to reduce the access delay and improve the processing efficiency.

Description

technical field [0001] The invention relates to the communication field, in particular to a multicast service processing method and system on a data network. Background technique [0002] Multicast technology is a point-to-multipoint network technology, and its purpose is to reduce the load of the network and the burden of the media server. Figure 1 is a schematic structural diagram of a multicast system. As shown in the figure, the multicast system consists of four parts: a video multicast service system, an IP metropolitan area network, an access network and a home network. The multicast service system implements video user management, CA / DRM, and video encoding functions, and then sends the video service stream to the IP MAN; the IP MAN sends the video service stream to the broadband access network through the IP multicast function; Network access realizes the control function of joining or leaving a video group, and sends the video stream required by the user to the use...
