Description
Technical Field

Background
At present, provincial and major prefectural broadcast television stations in China are in the exploratory stage of upgrading to ultra-high-definition systems. The SDI (serial digital interface) baseband technology is increasingly difficult to meet the requirements of service development in response to transmission, distribution and scheduling of ultra-high definition signals. In the related art, because the uncompressed media stream has a large data volume, a problem of network congestion may occur, and in order to achieve normal scheduling of the uncompressed media stream, there are two schemes for implementing processing of an ultra-high-definition signal, that is, the uncompressed media stream.
In the first related technology, the stream receiving device may be directly utilized to communicate with the network device receiving the media stream, and this way may occupy two signal bandwidths of the stream receiving device to implement stream pulling and address changing for different multicast addresses, which wastes bandwidth resources of the stream receiving device and results in a problem that the working efficiency of the receiving device is halved, although the scheduling of uncompressed media streams may be implemented.
In the second related technology, a multifunctional router is used to implement scheduling of uncompressed media streams, and although this method does not occupy twice the bandwidth of a stream receiving device, the router capable of implementing the above scheme is expensive, which results in high cost of the whole scheduling system, and is not suitable for the scenes of medium and small-sized scheduling systems (e.g., application scenes such as studios, relay carriages, etc.).

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a schematic view of a scene interaction of a media stream scheduling system based on a network device according to an embodiment of the present application, where the media stream scheduling system based on a network device may include a network device 200, a computer device 100 communicatively connected to the network device 200, and a plurality of media stream receiving devices 300, and the network device 200 further receives a plurality of media streams. In other embodiments of the present application, the network device based media stream scheduling system may also be composed of more or less components, which is not limited herein.

Wherein the target weight is used for characterizing the push order of the target media stream.
Step S203, receiving a pull request initiated by the target media stream receiving device 300, and pushing the target media stream to the target media stream receiving device 300 according to the pull request and the pushing sequence represented by the target weight.
In the embodiment of the present application, the computer device 100 may refer to a control device operated by a user, including but not limited to a mobile phone, a computer, or a server. Network device 200 may refer to a general-purpose network device 200 such as a switch or a general router. It should be understood that in the embodiment of the present application, the media stream received by the network device 200 may be from a media device, and the media device may be a device that generates a media stream in a media stream production scene (e.g., program production), such as a camera, a switching station, a gateway, and a server.

For example, the target media stream is a video/audio media stream of a program without compression from a camera, and needs to be scheduled to a switching station for processing, so that the switching station is the target access device. After determining the target media stream to be processed and the corresponding target media stream receiving device 300, the access control list sent by the computer device 100 may be received.
Upon receiving the access control list, the target media stream may be weighted using parameters configured in the access control list. In this embodiment of the present application, the target weight may represent a push sequence of a target media stream, and it should be noted that, a media stream scheduling scheme performed in this embodiment of the present application may not only process one target media stream, but also process a plurality of lossless and uncompressed media streams, and in a case of network congestion, the configured target weight determines a processing sequence of the target media stream by the network device 200, so that a target media stream that a user wants to process preferentially can be scheduled to the target media stream receiving device 300 for processing smoothly.
Through the scheme, the configured static routing list and the access control list are utilized, the network equipment 200 performs weighting processing on the target media stream, and then performs ordered scheduling, so that the problem that bandwidth of the media stream receiving equipment 300 needs to be occupied or expensive professional routing equipment needs to be introduced to realize lossless media stream scheduling in the related technology is solved, and non-blocking stream-by-stream scheduling of lossless and uncompressed audio and video IP streams is realized.
In one possible embodiment, please refer to fig. 3 in combination, the network device 200 includes a plurality of media stream inlets and a plurality of media stream outlets, the network device 200 receives a media stream through the media stream inlets, the network device 200 is communicatively connected to the media stream receiving device 300 through the media stream outlets, the static routing table includes a first corresponding relationship between the media stream inlets and the media stream outlets; the foregoing step S201 can be implemented by the following specific embodiments.
Substep S201-1 determines a target media stream inlet from the plurality of media stream inlets and a target media stream outlet from the plurality of media stream outlets corresponding to the target media stream inlet based on the first correspondence.
And a substep S201-2, determining the media stream accessed through the target media stream inlet as the target media stream.
Sub-step S201-3, the media stream receiving apparatus 300 communicatively connected through the target media stream outlet is determined as the target media stream receiving apparatus 300.
In this embodiment, the network device 200 may have a plurality of network ports, and may include a plurality of media stream inlets and a plurality of media stream outlets, where the media stream inlet may be a network port through which the network device 200 is communicatively connected to the aforementioned media device, and the multimedia stream outlet may be a network port through which the network device 200 is communicatively connected to the media stream receiving device 300, and may determine, according to the first corresponding relationship included in the static routing table, a target media stream that needs to be processed and a network port at which the target media stream receiving device 300 is located, so as to perform positioning of the target media stream and the target media stream receiving device 300. In the embodiment of the present application, the static routing table may be an IGMP (Internet Group Management Protocol) static routing table, so as to achieve the above-mentioned purpose.
In one possible embodiment, please refer to fig. 4 in combination, the access control list includes a second correspondence relationship between a plurality of priority identifiers and a plurality of weights, and the target media stream includes a pre-configured target priority identifier; the aforementioned step S202 may be implemented by the following steps.
The substep S202-1 determines a comparison priority flag identical to the target priority flag from the plurality of priority flags.
And a substep S202-2 of using the weight corresponding to the comparison priority mark as a target weight according to the second corresponding relation.
Sub-step S202-3, weighting the target media stream based on the target weight.
In this embodiment of the present application, the target media stream may be configured with a priority identifier in advance, and the network device 200 may determine the target weight matched with the priority identifier carried by the target media stream by using the access control list including a second corresponding relationship between a plurality of priority identifiers and a plurality of weights. In the embodiment of the present application, the Access Control list may be an Access Control List (ACL) policy, so as to determine and configure the target weight of the target media stream. For example, for a video stream and an audio stream, the video stream is relatively important, and the configured priority identifier may have a higher weight relative to the configured priority identifier of the audio stream. In addition, for the target media stream, the priority identifier of the main stream may also be higher than the corresponding weight of the priority identifier of the standby stream, and in other embodiments of the embodiment of the present application, the priority identifier may also be configured according to other criteria in advance, which is not limited herein.
In one possible embodiment, there are a plurality of target media streams, and a plurality of target media stream receiving devices 300; the embodiment of the present application also provides the following implementation modes.
Step S204, receiving the static routing table, determining a plurality of target media streams from the plurality of media streams according to the static routing table, and determining a plurality of target media stream receiving devices 300 corresponding to the plurality of target media streams from the plurality of media stream receiving devices 300.

As described above, the network device 200 can process a plurality of lossless, uncompressed audio/video streams in the same time period, and since the data amount of the plurality of media streams in this state is large, it is necessary to perform a sorting process. The static routing table may include a plurality of target media streams and a corresponding relationship between each target media stream and the target media stream receiving device 300 corresponding to each target media stream, based on which, the network device 200 may receive an access control list, and the access control list may also include a corresponding relationship between a priority identifier pre-configured for the plurality of target media streams and a weight corresponding to the priority identifier. Through the above steps, the network device 200 determines the corresponding relationship between each target media stream and the target media device, and determines the push sequence according to the target weight of each target media stream. Then, after receiving the pull stream request, the target media stream can be scheduled according to the determined push sequence. It should be noted that, in the case that a plurality of target media stream receiving devices 300 exist, each target media stream receiving device 300 may issue a pull stream request to the network device 200, and the network device 200 implements scheduling according to the determined push sequence, so as to solve various problems caused by network congestion.
In a possible implementation manner, the access control list further includes a sorting criterion, the network device 200 is configured with a plurality of push queues, and before the foregoing step S203, the following steps are further provided in this embodiment of the present application.
Step S207, classifying the plurality of target media streams according to the classification standard to obtain a classification result of each target media stream.

Accordingly, the foregoing step S206 may be implemented by the following steps.
Sub-step S206-1, receiving the pull request, determining a dequeuing order of the plurality of push queues according to the push order according to the pull request, so as to push the plurality of target media streams to the plurality of target media stream receiving devices 300.
It should be understood that, in an actual application scenario, after receiving a target media stream, the network device 200 classifies the target media stream into a push queue, in order to improve subsequent processing efficiency, the target media stream with a consistent classification result may be allocated to the same queue, and a specific classification criterion may be the same source IP address, destination IP address, source port number, destination port number, protocol number, and so on, without limitation, after the classification, the priority identifier configured for each target media stream is combined to perform weight allocation on the target media stream, so as to determine a dequeue sequence, and the target media stream is pushed to the corresponding target media stream receiving device 300 according to the dequeue sequence. In the embodiment of the present application, the above scheme may be implemented based on WFQ (Weighted Fair Queuing), and may also be implemented with reference to QoS (Quality of Service) technology.
