Detailed Description
Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
First, the noun terms to which one or more embodiments of the present application relate are explained.
Live streaming: the transmission of the live audio and video data is transmitted as a stable continuous flow to a user for watching through a network;
live broadcasting and stream pulling: the method comprises the steps of pulling a live broadcast stream to a source site appointed by a user through a live broadcast cloud platform;
edge computing node: a service for receiving a push flow;
and (4) rolling and releasing: and taking out one or more servers to stop service, and putting the servers into use again after updating is carried out.
Fig. 1 is a flowchart illustrating a method for rolling distribution of a live push streaming service according to an embodiment of the present application, where as shown in fig. 1, the method includes the following steps:
step S101, obtaining real-time use bandwidth of each edge computing node in the edge cluster, and calculating to obtain a first bandwidth utilization rate.
In the live broadcast process, after the anchor is played, as shown in fig. 2, the anchor requests the scheduling service to obtain a push stream address. The method includes that the heartbeat reported by an edge computing node is timed so as to report that the node is normal to a scheduling service, the scheduling service generally selects an edge computing node IP reported by the normal heartbeat to be allocated to an anchor IP, the anchor pushes a stream to the edge computing node corresponding to the IP address, and a CDN (Content Delivery Network) returns a source from the edge computing node and pulls the stream to a user for viewing. Both the hosted push flow and the CDN back source occupy the bandwidth of the edge compute node. The bandwidth of the edge computing node is the amount of data that can be transmitted in a unit time (generally, 1 second), and when the used bandwidth of the edge computing node reaches the configured bandwidth, the edge computing node cannot continue to carry more traffic, otherwise, the quality of the main stream and the quality of the user viewing are very poor due to network congestion.
In the prior art, when a version of a push streaming service is released, edge computing nodes are often manually selected to be released in batches, for example, 10 edge computing node update versions are selected at one time, and then 10 edge computing node update versions are selected at intervals of several hours, so that the release period is long, and much labor is consumed to participate. When the version is updated, edge computing nodes are selected randomly, for example, a cluster in the XX area includes 2 edge computing nodes, and if the 2 edge computing nodes are selected simultaneously when the edge computing nodes are selected randomly, the edge computing nodes cannot be distributed nearby when the XX area is in anchor push, which causes that only the edge computing nodes in a far area can be pushed, which causes that a network link is lengthened, and further, the network link is very easily affected by network fluctuation.
Based on the above consideration, in the embodiment of the present application, when the live streaming service is published in a rolling manner, the streaming service is distributed in a rolling manner by taking each edge cluster as a unit, so that not only are edge computing nodes in the edge cluster ensured to be normally executed by the main streaming, but also version updating of the streaming service of the edge computing nodes can be realized. Specifically, the real-time bandwidth used by each edge computing node in the edge cluster is obtained first, so that whether the edge computing node has a link with a main broadcast, a CDN and the like can be determined, and whether the edge computing node is offline or not can be determined subsequently. Specifically, according to the real-time bandwidth of each edge computing node and the pre-agreed configuration bandwidth of each edge computing node, the first bandwidth utilization rate may be calculated, for example, the first bandwidth utilization rate = the sum of the real-time bandwidth of each edge computing node/the configuration bandwidth of the edge cluster, and the configuration bandwidth of the edge cluster is determined according to the sum of the configuration bandwidth of each edge computing node.
And step S102, determining a target edge computing node to be offline in the edge cluster according to the first bandwidth utilization rate.
The current real-time use bandwidth of the edge cluster can be determined according to the first bandwidth utilization rate, so that the consumed bandwidth meeting the requirements of main broadcasting push flow, source return and the like can be determined, edge computing nodes corresponding to other bandwidths can be used as target edge computing nodes to be offline, the target edge computing nodes to be offline do not influence the requirements of live broadcasting on the bandwidth, and the target edge computing nodes which continuously provide services can be ensured to exist in the edge cluster.
And step S103, downloading the target edge computing node, and updating the push flow service version of the target edge computing node.
After the target edge compute node is determined, it may be set offline. When the edge computing node is offline, the state of the target edge computing node may be marked as an offline state, or may be set in other manners of distinguishing different states of the offline target edge computing node and the normally operating edge computing node, which is not limited herein. And the offline target edge computing node does not continue to carry traffic any more so as to ensure that the live streaming is not influenced by the version updating of the streaming service. When updating, the new version can be directly issued to the offline target edge computing node, and the target edge computing node automatically updates the version.
And step S104, updating the target edge computing node on line.
After the version of the target edge computing node is updated, if the state of the target edge computing node is marked as the online state again, the updated target edge computing node is online again, and the like, the target edge computing node starts to bear the flow again.
Step S105, judging whether the push flow service of all edge computing nodes in the edge cluster completes version updating.
After the target edge computing node is updated online again, judging whether the push flow services of all edge computing nodes in the edge cluster finish the version updating or not, if so, finishing the version updating of the push flow service; if not, the steps S101-S104 are executed in a circulating manner, the target edge computing nodes which are determined to be offline are subjected to push flow service rolling release, namely after the versions of the push flow service are updated when partial target edge computing nodes in the edge cluster are offline, the target edge computing nodes are online again, then other target edge computing nodes are offline, and the versions of the push flow service are updated until the push flow service of all the edge computing nodes in the edge cluster is updated.
The overall processing flow is as shown in fig. 3, in the embodiment of the present application, the scheduling service executes the above steps, and after determining the target edge computing node, the scheduling service configures a corresponding target edge computing node to be offline, updates its plug flow service version, and automatically sends the version to the offline target edge computing node (i.e., the version service in fig. 3), thereby implementing automatic update of the plug flow service version of the edge computing node.
According to the live streaming service rolling release method, the target edge computing node is determined according to the first bandwidth utilization rate to carry out the rolling release of the streaming service, so that the influence on the anchor is avoided when the version is updated, and the existence of the available edge computing node is guaranteed. And the off-line and on-line of the target edge computing node and the version updating of the plug-flow service are automatically completed, so that the labor cost for manual version updating is saved.
Fig. 4 is a flowchart illustrating a method for roll publishing of a live push streaming service according to an embodiment of the present application, where the method includes the following steps, as shown in fig. 4:
step S401, determining whether the current time is the offline time of the preset edge computing node.
When the push flow service is updated, the offline time of the edge computing node may also be preset, that is, the update time of the push flow service is preset, for example, 12-00. The offline time of the preset edge computing node may be set according to implementation, and is not limited herein.
Judging whether the current time is the offline time of a preset edge computing node, if so, executing a subsequent step S402 to select a target edge computing node to be offline and updating the push flow service; if not, if the live broadcast late peak time period is 20-00, each edge computing node receives a large amount of push streams, and the push stream service version is updated at this time, which easily causes the problems of poor viewing experience of users and the like, and the target edge computing node to be offline can be selected to update the push stream service after waiting for the offline time of the preset edge computing node. Or, if the current time is determined to be the offline time of the preset edge computing node, and according to the historical data, the offline time of the edge computing node at the preset edge computing node does not carry traffic or carries less traffic, in the offline time period of the preset edge computing node, the edge computing node may be directly offline, and the push flow service version of the offline edge computing node is updated, which is not limited herein.
Step S402, obtaining real-time use bandwidth of each edge computing node in the edge cluster, and calculating to obtain a first bandwidth utilization rate.
This step can refer to the description of step S101, and is not described herein again.
In step S403, it is determined whether the first bandwidth utilization rate is lower than a preset first utilization rate threshold.
The first bandwidth utilization rate represents the bandwidth utilization condition of the edge cluster, and the first bandwidth utilization rates at different time are different according to the actual condition. Considering that when the first bandwidth utilization rate is higher, such as 80% or more, in order to provide better viewing effect for users, a part of idle bandwidth is reserved to avoid the problems of sudden bandwidth usage increase, insufficient bandwidth and the like. Therefore, in the embodiment of the present application, the first bandwidth utilization rate is determined, and when it is determined whether the first bandwidth utilization rate is lower than the preset first utilization rate threshold, if the preset first utilization rate threshold is set to 40%, if yes, step S404 is executed to determine the target edge computing node to be offline, and if not, the waiting may be continued, and after the first bandwidth utilization rate is lower than the preset first utilization rate threshold, processing and the like are performed.
Step S404, determining reserved use bandwidth according to the first bandwidth utilization rate and the configuration bandwidth of the edge cluster; determining idle bandwidth according to reserved use bandwidth and configuration bandwidth of the edge cluster; and determining a target edge computing node to be offline according to the idle bandwidth.
The current used bandwidth of the edge cluster may be determined according to the first bandwidth usage rate and the configured bandwidth of the edge cluster, for example, if the first bandwidth usage rate is 40%, and the configured bandwidth of the edge cluster is at most 20G, it may be determined that the current used bandwidth is 20 × 40% =8G. In order to guarantee the watching quality of users, the reserved use bandwidth needs to be larger than the current use bandwidth, and the users can be guaranteed to respond to various bandwidth use conditions in time, such as suddenly increasing the stream pushing flow and the like. The reserved usage bandwidth may be 2 times of the current usage bandwidth, such as 8 × 2 =1lg, which is set according to the implementation, and is not limited herein. According to the reserved use bandwidth and the configuration bandwidth of the edge cluster, the idle bandwidth can be determined. Free bandwidth = configured bandwidth of edge cluster-reserved used bandwidth, e.g. 20-16=4g.
According to the idle bandwidth and the configuration bandwidth of the edge computing nodes, target edge computing nodes to be offline can be determined, such as the idle bandwidth 4G, the configuration bandwidth of each edge computing node is 2G, and the number of the target edge computing nodes to be offline is 4/2=2. Because a plurality of edge computing nodes exist in the edge cluster, when a target edge computing node to be offline is determined, the real-time use bandwidths of the edge computing nodes of which the versions are not updated can be sequenced from small to large, namely the edge computing nodes with more idle bandwidths are sequenced first, so that the influence on a main broadcast and a user during offline is reduced as much as possible, a plurality of edge computing nodes which are sequenced first and meet the offline number are selected as the target edge computing nodes to be offline, and the lower line number is 2 for example, 2 edge computing nodes which are sequenced first are selected as the target edge computing nodes to be offline; or, the flow borne by the edge computing node may be a push flow of 1 anchor, or may be a push flow of multiple anchors, the push flow time durations of different anchors cannot be determined, and the affected user groups cannot be determined, and multiple edge computing nodes with the number of downlinks and with the version not updated may be randomly selected as target edge computing nodes to be downlinked. For example, the specifically selected target edge computing node to be offline may be set according to an implementation situation, and is not limited herein.
And step S405, downloading the target edge computing node, and updating the push flow service version of the target edge computing node.
And marking the state of the target edge computing node as an offline state to finish the offline of the target edge computing node. After the stream is off line, considering that the target edge computing node may still have the situation that the anchor stream is not finished or the user still watches at present, directly updating the version of the stream pushing service may also affect the anchor or the user, and therefore, before updating the version of the stream pushing service, whether the target edge computing node meets the preset updating check condition is judged. The preset updating verification conditions include whether the second broadband utilization rate of the target edge computing node is lower than a preset second utilization rate threshold value or not, whether the real-time user watching number of the live stream of the target edge computing node is lower than a preset number threshold value or not and the like. The second bandwidth usage rate is determined according to a ratio of a real-time usage bandwidth of the target edge computing node to a configuration bandwidth of the target edge computing node, for example, the second bandwidth usage rate = real-time usage bandwidth of the target edge computing node/configuration bandwidth of the target edge computing node. If the preset second utilization rate threshold is set to 1% (here, considering that 24-hour stream pushing may exist, the preset second utilization rate threshold is set to 1%), and when the second bandwidth utilization rate is lower than the preset second utilization rate threshold, it is determined that the preset update verification condition is met; or the preset number of people threshold is set to be 10 people, the real-time user watching number of each live stream on the target edge computing node is obtained, when the number of the live streams is lower than the preset number of people threshold, the influence on the users is small, and the judgment is made to accord with the preset updating verification condition; or when all the conditions are met, judging that the preset updating verification condition is met, and not limiting the situation.
And after judging that the preset updating and checking conditions are met, issuing an updating version to the target edge computing node for updating the push flow service version.
Step S406, the updated target edge computing node is online.
When the target edge computing node updates the push stream service version, the scheduling service can also acquire heartbeat information reported by the target edge computing node in real time, wherein the heartbeat information comprises version information. Judging whether the version information is the updated version information or not, if so, comparing the version information with the issued updated version information, and judging whether the version information is consistent with the issued updated version information; or comparing the version information with the version information of the previous heartbeat information, judging whether the version information is inconsistent or not, and the like, thereby determining whether the version information is updated version information or not. And if the version information is judged to be updated version information, determining that the push flow service version of the target edge computing node is updated, marking the state of the target edge computing node as an online state, and online the target edge computing node after updating the push flow service version to enable the target edge computing node to bear the flow again.
Step S407, after the target edge computing node is updated online, acquiring heartbeat information reported by each edge computing node in the edge cluster in real time, and determining whether version information in the heartbeat information is updated version information.
After the target edge computing node is updated online, acquiring heartbeat information reported by each edge computing node in the edge cluster in real time, judging whether version information in the heartbeat information is updated version information, if not, indicating that edge computing nodes with un-updated versions exist, repeatedly executing the steps S402-S406, and performing rolling release on the edge computing nodes with un-updated versions until version information in the heartbeat information reported by all edge computing nodes of the edge cluster is updated version information, and updating the push flow service versions of all edge computing nodes of the edge cluster is completed.
According to the live streaming service rolling publishing method, the target edge computing node to be offline is selected within the offline time range of the preset edge computing node, and the influence on the anchor and the user is reduced.
