Detailed Description
In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.
It is to be understood that, hereinafter, "at least one" means one or more, "a plurality" means two or more. "and/or" is used to describe the association relationship of the associated object, and indicates that there may be three relationships, for example, "a and/or B" may indicate: only A, only B and both A and B are present, wherein A and B may be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. "at least one of the following" or similar expressions refer to any combination of these items, including any combination of the singular or plural items. For example, at least one (one) of a, b, or c, may represent: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", wherein a, b and c may be single or plural.
Fig. 1 is a flowchart of a stream pulling method shown in an embodiment of the present disclosure, where the stream pulling method may be applied to, for example, stream pulling nodes, such as node 1, of a video live broadcast system shown in fig. 2, where each node, such as nodes 1 to node N, may specifically be, for example, a P2P live broadcast client, the live broadcast clients are in communication connection with each other and with a P2P cluster scheduling server, and the scheduling server may manage joining, leaving, and the like of each live broadcast client, such as a live broadcast client, in a cluster. A pull node, such as node 1, may obtain node information, such as node IP addresses, node names, etc., for other nodes, such as nodes 2-N, from the dispatch server. The pull flow node such as the node 1 sends a connection establishment request based on the acquired node information to establish a communication connection with other nodes such as the nodes 2-N, and then the information can be exchanged. Specifically, the stream pulling method may include the following steps:
step S101: and acquiring video playing positions and data transmission quality parameters of other nodes connected with the stream pulling node.
Illustratively, the data transmission quality parameter is used to indicate the data transmission quality of a node, and the larger the data transmission quality parameter is, the better the data transmission quality is. The video playing position may be determined by a playing time when a node plays a video or a video frame identifier, such as a unique ID, but is not limited thereto.
Specifically, after the stream pulling node, such as node 1, successfully establishes a communication connection with all or part of the other nodes, such as nodes 2-N, the video playing position and the data transmission quality parameter of the other nodes in communication connection with the stream pulling node may be interactively obtained.
Step S102: and selecting at least one target node which meets a preset pull stream condition from the other nodes based on the video playing position and the data transmission quality parameter of each node in the other nodes. The preset stream pulling condition comprises that the data transmission quality parameter of the node is larger than a preset transmission quality parameter threshold value, and the video playing position of the node leads the video playing position of the stream pulling node.
For example, the video playing position of the node in the preset pull stream condition leads the video playing position of the pull stream node, that is, for example, the video playing progress of the node a is greater than the video playing progress of the pull stream node, which means that the slice data of the live video obtained by the node a is greater than the slice data of the pull stream node.
Specifically, the stream pulling node determines whether the video playing position and the data transmission quality parameter of each of the other nodes satisfy the preset stream pulling condition, and determines the node satisfying the preset stream pulling condition as a target node, for example, determines the node 4 and the node 5 as target nodes.
Step S103: and acquiring slice data required by the pull flow node from the at least one target node.
Specifically, the pull flow node may generate a pull flow request, and send the pull flow request to each target node, where the pull flow request carries identification information of a slice required by the pull flow node.
In one example, after determining the target node, the pull flow node generates a pull flow request and sends the pull flow request to each of the target nodes, such as node 4 and node 5, where the pull flow request carries identification information, such as an index number, of a slice required by the pull flow node. For example, the identification information of the required slice may be an identification of the slice data, such as an index number, etc., for example, if the slice data currently obtained by the pull flow node is the slice data with index numbers 2, 4, 6, 8, 10, the required slice, i.e., the still worse slice, is the slice data with index numbers 1, 3, 5, 7, 9, the pull flow request will carry the index numbers of the required slices, such as 1, 3, 5, 7, 9.
Specifically, after each target node receives the pull flow request, the pull flow request is responded, and the slice data of the target node is returned to the pull flow node. For example, node 4 returns slice data with index numbers 1, 3, and 5, and node 5 returns slice data with index numbers 7 and 9.
According to the stream pulling method provided by the embodiment of the disclosure, the video playing positions and the data transmission quality parameters of the other nodes connected with the stream pulling node are obtained, then the target nodes meeting the preset stream pulling condition are screened based on the video playing positions and the data transmission quality parameters of the other nodes, and finally the slice data are obtained by interacting with the target nodes, so that the screened target nodes can be ensured to have the slice data required by the stream pulling node, and the data transmission quality of the target nodes is ensured to a certain extent, some unnecessary or invalid interaction processes and/or data processing processes in the node resource sharing process are avoided, the transmission efficiency of the shared slice data is improved, the overall sharing rate of the node resources is higher, the video playing quality of the nodes can be improved, and the transmission pressure of the P2P flow to the whole network is relieved to a certain extent.
Optionally, in some embodiments of the present disclosure, the data transmission quality parameter may include, but is not limited to, at least a data transmission speed and/or a data transmission ratio. The data transmission ratio represents the ratio of the data transmission amount of one node to the data transmission amount of the other nodes in a historical preset time. Correspondingly, when the pull flow node determines whether the data transmission quality parameter of each of the other nodes meets the preset pull flow condition in step S102, the node in which the data transmission speed is greater than the preset data transmission speed threshold and/or the data transmission ratio is greater than the preset data transmission ratio threshold in each node is determined as the target node. The preset data transmission ratio threshold and the preset data transmission speed threshold may be set according to specific situations, and the preset data transmission ratio threshold may be, for example, 50%, which is not particularly limited in this embodiment. Through the embodiment, the data transmission quality of the screened target node can be further improved, the transmission efficiency of the shared slice data is further improved, and the overall sharing rate of the node resources is further improved.
Optionally, on the basis of the above embodiments, in some embodiments of the present disclosure, with reference to fig. 3, the method may further include the following steps:
step S301: and acquiring the communication quality parameters of the target node connected with the stream pulling node.
For example, in some embodiments of the present disclosure, the communication quality parameter may include at least one or more of, but is not limited to, a communication link status parameter, a duration of time for which the target node has not returned slice data. The communication link status parameter may be "0" (indicating that the link is down) or "1" (indicating that the link is normal), but is not limited to this form. The duration that the target node does not return the sliced data, that is, the data is not returned after time out, indicates that the communication quality of the target node is poor, and the duration may be set according to needs, which is not limited in this embodiment.
Specifically, the stream pulling node may obtain a communication quality parameter of a target node in communication connection with the stream pulling node, such as a communication link state parameter, and a duration of the slice data not returned by the target node.
Step S302: and when the communication quality parameters meet the preset communication quality parameter conditions, sending a cancellation request to the target node, wherein the cancellation request indicates that the target node does not carry out stream pushing and returns the sliced data any more.
For example, the condition that the preset communication quality parameter is satisfied may be that the communication link state parameter is "0", or the communication link state parameter is "1" and the duration T that the target node does not return the slice data is greater than a preset maximum duration Tmax, which may be specifically set, which is not limited in this embodiment.
Specifically, when the obtained communication quality parameter of the target node meets the preset communication quality parameter condition, the stream pulling node sends a cancellation request to the target node to indicate that the target node does not perform stream pushing any more and returns slice data. For example, if the communication quality parameter of the target node, such as the node 4, meets the preset communication quality parameter condition, a cancellation request is sent to the node 4 to indicate that the node 4 no longer performs the push flow and returns the sliced data.
According to the scheme, the cancellation request can be sent to the target node which does not meet the communication quality requirement in time, so that unnecessary data interaction and data processing processes are avoided, the transmission efficiency of shared slice data is improved, and the overall sharing rate of node resources is improved to a certain extent.
Optionally, on the basis of the foregoing embodiment, in some embodiments of the present disclosure, after the cancellation request is sent to the target node in step S103, the method may further include the following steps: and forwarding a pull flow request which is sent to the target node by the pull flow node to other target nodes, wherein the pull flow request is used for requesting to acquire the slice data required by the pull flow node from the target node.
Specifically, for example, the pull flow node sends a cancel request to a target node, such as the node 4, which indicates that the communication quality of the target node is degraded, and then sends the pull flow request a, which was sent to the node 4 by the pull flow node, to another target node, such as the node 5, again. The pull flow node may then receive the slice data returned by node 5 in response to pull flow request a.
By the scheme of the embodiment, after the cancellation request is sent to the target node which does not meet the communication quality requirement, the slice data can be obtained from other target nodes in time, the slice data sharing efficiency is improved to a certain extent, and the overall sharing rate of node resources is further improved.
Optionally, on the basis of the foregoing embodiments, referring to fig. 4, in some embodiments of the present disclosure, the method may further include the following steps:
step S401: and acquiring the service type of the live video at the current moment of the video live broadcast system.
Illustratively, the service type may be a live video service with high real-time requirement, such as live news, or a live service with low real-time requirement, but is not limited thereto. The service types can also be divided according to the clear height of the live pictures. The stream pulling node can acquire the parameter information of the service type of the current live video from the scheduling server, and the service type can be determined based on the parameter information.
Step S402: configuring the preset transmission quality parameter threshold value based on the service type; wherein, different service types correspond to different preset transmission quality parameter thresholds.
Illustratively, the mapping relationship between different service types and corresponding different preset transmission quality parameter thresholds can be preset, so that parameter configuration can be conveniently realized. Specifically, after determining the service type of the current live video, the stream node configures a preset transmission quality parameter threshold in a preset stream pulling condition based on the service type, and then may jump to execute step S101.
In this embodiment, the preset transmission quality parameter threshold in the preset pull-stream condition may be adjusted according to different live broadcast service types, so that the screened target node more matches the corresponding live broadcast service, thereby reducing the potential influence on the live broadcast service, further improving the transmission efficiency of node shared slice data, and making the overall sharing rate of node resources higher.
Optionally, on the basis of the foregoing embodiments, in some embodiments of the present disclosure, the method may further include the following steps: and when a refusal request sent by the target node is received, the pull flow request is not sent to the target node. The rejection request is generated by the target node when the load of the target node is greater than a preset load threshold, and the preset load threshold is related to at least one of the number of pull stream nodes supported by the target node and the type of service of the live video.
Specifically, the target node may determine whether to support the new pull request according to a load condition of the target node, and if the load is too large, the target node may not support the new pull request, and at this time, the target node may change state information of the target node in time, and send a reject request to the pull node, and reject the new pull request.
Illustratively, the target node generates the reject request when its own load is greater than a preset load threshold. The preset load threshold may be determined by the number of pull stream nodes supported by the target node and/or the service type of the live video, but is not limited thereto, and may be flexibly set according to the need, which is not limited in this embodiment. For example, a target node only supports the pull requests of two pull nodes, and when a third pull node sends a pull request, the pull request of the third pull node is rejected. When the real-time requirement of the service type of live video is high, the preset load threshold may be set to a first value, and when the real-time requirement is low, the preset load threshold may be set to a second value, where the second value is greater than the first value, and the first value may be set according to specific needs, which is not limited in this embodiment.
In this embodiment, video playing positions and data transmission quality parameters of other nodes connected to the stream pulling node are obtained, then a target node meeting a preset stream pulling condition is screened based on the video playing positions and the data transmission quality parameters of the other nodes, and finally slice data is obtained by interacting with the target node, so that it can be ensured that the screened target node has slice data required by the stream pulling node, and the data transmission quality of the target node has certain guarantee, some unnecessary or invalid interaction processes and/or data processing processes in a node resource sharing process are avoided, the transmission efficiency of shared slice data is improved, the overall sharing rate of node resources is higher, the video playing quality of the node can be improved, and the transmission pressure of P2P traffic on the whole network is relieved to a certain extent.
It should be noted that although the steps of the methods of the present disclosure are depicted in the drawings in a particular order, this does not require or imply that the steps must be performed in this particular order or that all of the depicted steps must be performed to achieve desirable results. Additionally or alternatively, certain steps may be omitted, multiple steps combined into one step execution, and/or one step broken into multiple step executions, etc. Additionally, it will also be readily appreciated that these steps may be performed synchronously or asynchronously, e.g., among multiple modules/processes/threads.
