The invention provides a node adjusting method.
Referring to fig. 2, fig. 2 is a schematic flow chart of the first embodiment of the present invention.
In a first embodiment, the method may comprise:
s10: determining a service node corresponding to the target video stream;
the shared computing is based on a block chain technology, resources such as idle bandwidth, storage and computing in a common household of the society are recorded and summarized through authorized intelligent hardware equipment, computing resources which are faster, easier to expand and more environment-friendly are provided through a cross-platform and low-power-consumption virtualization technology and an intelligent scheduling technology of near point-to-point access of nodes, in a live broadcast scene of shared computing, services such as transmission, playing, access and the like are generally provided for video streams through setting nodes, and the nodes are intelligent hardware deployed in the common household and have the advantage of low cost. For a certain specified video stream in a live broadcast scene, that is, the target video stream, the number of nodes providing services for the video stream is not unique, and this step is intended to achieve determination of the service nodes thereof, specifically, traversal is performed on the target video stream in the system network, that is, each service node corresponding to the target video stream can be determined.
S11: acquiring service parameters of each service node;
specifically, each service node may provide limited services for the video stream, and it is understood that the type of the service referred to herein is not unique, for example, the service may be an upstream bandwidth for transmitting the video stream, the number of SDKs for accessing the video stream, an operating memory for playing the video stream, a storage space for storing the video stream, and the like, and specifically, when a certain service exceeds a corresponding standard value during use, the service node may not provide a stable service for continuing the video stream. Therefore, the specified service parameter can be used as a basis for adjustment, and this step is intended to implement calculation on the current data of the specified service in the service node to obtain a corresponding service value, i.e., the service parameter, where the service parameter may be one or more of the services of the plurality of types.
S12: obtaining information of each service node to be adjusted according to the service parameters and a preset adjustment strategy;
specifically, a corresponding adjustment policy may be preset for the service parameter, so that after obtaining the service parameter corresponding to the target video stream, the service node to be adjusted, that is, the service node to be adjusted, may be determined in all the service nodes based on the preset adjustment policy, and then node information corresponding to each service node to be adjusted, that is, the service node information to be adjusted, may be obtained. The preset adjustment strategy is set by a technician according to actual conditions, and the specific content does not affect the implementation of the technical scheme, which is not limited in the present application.
Preferably, before the obtaining the information of each service node to be adjusted according to the preset adjustment policy, the method may further include: calculating and obtaining an average service parameter of each service node according to the service parameters; judging whether the average service parameter exceeds a preset threshold value; and if not, executing the step of obtaining the information of each service node to be adjusted according to the preset adjustment strategy.
In order to avoid unnecessary waste of running resources due to excessive adjustment, before node adjustment is performed, a judgment on whether node adjustment is required or not may be performed, specifically, an average service parameter of a service node is calculated according to a service parameter obtained based on S11, and if the average service parameter exceeds a corresponding preset threshold, it is indicated that loads of all service nodes of a target video stream are in a higher state, and even if node adjustment is performed continuously, it is difficult to improve the resource utilization rate of the service node, so node adjustment is not required any more; on the contrary, if the average service parameter does not exceed the preset threshold, it indicates that most of the service nodes of the target video stream are in a low load state, and the resource waste is high, so that node adjustment can be performed to concentrate the clients corresponding to the target video stream on fewer service nodes, and improve the resource utilization rate. The preset threshold may be set by a technician according to actual requirements, and the present application is not limited thereto, for example, global information may be referred to, and all video stream information with resources matched with bandwidth may be referred to.
Preferably, the obtaining of the service node information to be adjusted according to the preset adjustment policy may include: and taking the service node with the service parameter lower than the preset threshold value as a service node to be adjusted, and acquiring the information of the service node to be adjusted.
The preferred embodiment provides a specific preset adjustment policy, and specifically, a service node with a service parameter lower than a corresponding preset threshold value may be used as the service node to be adjusted, so as to obtain corresponding information of the service node to be adjusted. For example, when the uplink bandwidth is selected as the service parameter, the current uplink bandwidth of each service node may be counted, and the service node with the uplink bandwidth lower than the preset standard may be used as the service node to be adjusted.
Preferably, the service parameters may include the number of client connections and the upstream bandwidth.
The preferred embodiment provides specific types of service parameters, namely client connection number and upstream bandwidth. It can be understood that the selection of the service parameter type is only one implementation manner provided in the present application, and may be other types, which do not affect the implementation of the present technical solution.
Preferably, the taking the service node with the service parameter lower than the preset threshold as the service node to be adjusted may include: sequencing the service nodes according to the ascending bandwidth from small to large; and selecting the service nodes in a preset range as the service nodes to be adjusted from the service nodes with the client connection number lower than the first threshold value.
Specifically, when the uplink bandwidth and the number of client connections of the designated service node are used as service parameters, the corresponding preset adjustment policy may be set as follows: firstly, counting the uplink bandwidth and the client connection number of each service node in a target video stream, and arranging each service node according to the sequence of the uplink bandwidth from small to large; further, selecting a service node to be adjusted from service nodes with the client connection number lower than a first threshold value, wherein the first threshold value is a standard value corresponding to a preset client connection number and is equivalent to the preset threshold value; further, when the service nodes to be adjusted are selected, because the number of the service nodes in one video stream is large, in order to ensure the adjustment efficiency, the adjustment efficiency can be achieved by a small-batch multiple adjustment method, that is, the service nodes in a preset range are selected as the service nodes to be adjusted from the service nodes of which the connection number of the client is lower than the first threshold, wherein the specific value of the preset range can be set according to the actual situation. Therefore, the service nodes which occupy lower uplink bandwidth and have fewer client connections in all the service nodes are taken as the service nodes to be adjusted so as to adjust the nodes, and resource occupation and resource waste are effectively avoided.
S13: and sending the information of each service node to be adjusted to the client so that the client adjusts the corresponding service node to be adjusted according to the information of the service node to be adjusted.
In this step, to implement adjustment of the service node to be adjusted, after the service node to be adjusted is determined based on S12, the obtained information of each service node to be adjusted may be sent to the client, so that the client may determine the service node to be adjusted based on the information of the service node to be adjusted and effectively adjust the service node.
In the node adjustment method provided by this embodiment, a service parameter specified in a service node of a video stream is used as an adjustment index, and node information of the service node that needs to be adjusted in the video stream, that is, the information of the service node to be adjusted, is determined according to a preset adjustment policy for the service parameter, so that a client dynamically adjusts the corresponding service node to be adjusted based on the information, and thus, for a certain specific video stream, corresponding SDKs are concentrated into fewer nodes, thereby implementing efficient utilization of the service node in a system and avoiding resource waste; meanwhile, due to the fact that resource release and node adjustment are conducted on the service node of the transferred SDK, service convenience is provided for other video streams, resource waste is further avoided, and the node utilization rate is maximized.
The invention provides another node adjusting method.
Referring to fig. 3, fig. 3 is a schematic flow chart of a second embodiment of the present invention.
In a second embodiment, the method may comprise:
s20: determining a service node corresponding to the target video stream;
s21: acquiring the client connection number and uplink bandwidth of each service node;
s22: sequencing the service nodes according to the ascending bandwidth from small to large;
s23: selecting service nodes in a preset range as service nodes to be adjusted from the service nodes with the client connection number lower than a first threshold value, and acquiring information of the service nodes to be adjusted;
s24: sending the information of each service node to be adjusted to the client so that the client adjusts the corresponding service node to be adjusted according to the information of the service node to be adjusted;
s25: counting the current adjusting time, and judging whether the current adjusting time reaches a preset timestamp; if yes, executing S26, otherwise, returning to S22 until the current adjustment time reaches the preset time stamp.
The embodiment of the application provides a specific node adjustment method, namely, a service node is dynamically adjusted by taking a timestamp as a standard. Specifically, taking the uplink bandwidth and the number of client connections as examples, after one node adjustment is completed based on a corresponding adjustment policy, statistics may be performed on the current adjustment time, and if the current adjustment time has not reached the preset timestamp, the operation returns to S22 to reorder the service nodes, and readjustment of the service nodes is performed until an iteration termination condition is satisfied, that is, the current adjustment time reaches the preset timestamp, and the node adjustment is ended. Therefore, through multiple dynamic adjustment in a small range, the SDK of the target video stream is stably concentrated into fewer service nodes as much as possible, and the resource utilization of the nodes is maximized.
It should be noted that, in the process of each iterative adjustment, values of the corresponding preset ranges may be the same or different, and the implementation of the technical scheme is not affected. In addition, the specific value of the preset timestamp also does not affect the implementation of the technical scheme, and the application does not limit the specific value.
As a preferred embodiment, the node adjustment method further includes: when the current adjusting time reaches the preset timestamp, if the client connection number of the service node is lower than a first minimum threshold and the uplink bandwidth is lower than a second minimum threshold, a forced disconnection instruction is sent to the client so that the client is disconnected with the service node.
Specifically, when the current adjustment time reaches the preset timestamp and one iteration adjustment is completed, statistics of the uplink bandwidth and the number of client connections of each service node can be continuously performed, if a service node with a low number of client connections and a low uplink bandwidth still exists, in order to ensure effective utilization of node resources, a forced point quitting strategy can be executed on the part of service nodes, namely, clients connected to the part of service nodes are forced to quit, and the part of service nodes are recovered. It can be understood that the specific values of the first minimum threshold and the second minimum threshold may be set by user according to actual situations, and the implementation of the technical scheme is not affected.
As a preferred embodiment, the node adjustment method further includes: selecting a preset number of service nodes as connectable service nodes from the service nodes with the uplink bandwidth higher than the average uplink bandwidth, and acquiring corresponding connectable service node information; and sending the connectable service node information to the client so as to establish connection between the client and the connectable service node.
Specifically, the node adjustment aims at connecting the client to a small number of service nodes in a centralized manner so as to reduce the occupation of the service nodes, so that in the node adjustment process, before the client is disconnected from the corresponding node to be adjusted based on the information of the node to be adjusted, the connectable service node can be selected and connected with the connectable service node, and the service on the node to be adjusted is transferred to the connectable service node so as to avoid service interruption. Further, in a specific implementation process, an average uplink bandwidth is calculated and obtained based on the uplink bandwidth of each service node, a preset number of service nodes are selected from the service nodes with the uplink bandwidth higher than the average uplink bandwidth to serve as connectable service nodes, information of the connectable service nodes is obtained, and the information is sent to the client side so that the client side can establish connection with the corresponding connectable service nodes based on the information. The specific value of the preset number is set according to the actual situation, and the method is not limited in the application.
In addition, for the specific implementation process of S20-S24, reference may be made to the previous embodiment, and details of this embodiment are not described herein again.
The invention provides a node adjusting method.
Referring to fig. 4, fig. 4 is a schematic flow chart of a third embodiment of the present invention.
In a third embodiment, the method may comprise:
s30: receiving service node information to be adjusted sent by a management end; the service node information to be adjusted is obtained by the management terminal through obtaining the service parameters of each service node corresponding to the target video stream and according to a preset adjustment strategy;
s31: and adjusting the corresponding service node to be adjusted according to the information of the service node to be adjusted.
In this embodiment, a node adjustment method provided by the present application is introduced from a client perspective, and specifically, after obtaining service node information to be adjusted based on a preset adjustment policy, a management end may issue the service node information to be adjusted to the client, so that the client may adjust a corresponding service node to be adjusted according to each service node information to be adjusted.
Preferably, the adjusting the corresponding service node to be adjusted according to the service node information to be adjusted may include: receiving connectable service node information issued by a management end; establishing connection with the corresponding connectable service node according to the connectable service node information; and disconnecting the service nodes to be adjusted.
Specifically, after the client obtains the connectable service node information issued by the management terminal, the client can establish connection with the corresponding connectable service node based on the connectable service node information, and disconnect the information with the service node to be adjusted from the corresponding service node to be connected, thereby completing node adjustment.
Preferably, the node adjusting method may further include: and when receiving a forced disconnection instruction issued by the management end, disconnecting the service node specified by the forced disconnection instruction and establishing connection with the edge server.
Specifically, after the client disconnects from the designated service node based on the forced disconnection instruction issued by the management terminal, in order to ensure normal operation of the user service, the client may establish connection with the edge server, so as to transfer the service in the disconnected service node to the edge service for continuing operation, thereby ensuring user experience.
It can be seen that, in the node adjustment method provided in this embodiment, a service parameter specified in a service node of a video stream is used as an adjustment index, and node information of a service node that needs to be adjusted in the video stream, that is, the information of the service node to be adjusted, is determined according to a preset adjustment policy for the service parameter, so that a client dynamically adjusts the corresponding service node to be adjusted based on the information, and thus, for a certain specific video stream, corresponding SDKs are concentrated into fewer nodes, thereby implementing efficient utilization of the service nodes in a system and avoiding resource waste; meanwhile, due to the fact that resource release and node adjustment are conducted on the service node of the transferred SDK, service convenience is provided for other video streams, resource waste is further avoided, and the node utilization rate is maximized.
In another embodiment of the present invention, the method includes the following steps:
(1) data summarization:
in this embodiment, the SDK number (the number of client connections) and the uplink bandwidth are set as the specified resource indexes, i.e., the service parameters, where the uplink bandwidth is used as the main adjustment index, the SDK number is used as the auxiliary reference index, and meanwhile, according to the online situation, the upper threshold, i.e., the preset threshold, is set for the SDK number and the uplink bandwidth.
(2) Establishing and executing a node adjustment strategy:
firstly, determining a service node corresponding to each video stream, and acquiring the current SDK number and the current uplink bandwidth in each service node, thereby calculating and acquiring the total SDK number and the total uplink bandwidth of the corresponding video stream, and finally calculating and acquiring the average SDK number and the average uplink bandwidth corresponding to the video stream.
Further, whether the average SDK number of each video stream exceeds the corresponding preset threshold or not or whether the average uplink bandwidth exceeds the corresponding preset threshold or not is judged, if yes, node adjustment is stopped, and if not, node adjustment is started.
Furthermore, all service nodes of the video stream to be adjusted are arranged according to the ascending bandwidth from small to large, the ordered node queues are traversed, and respective corresponding adjustment strategies are formulated. Specifically, for any node queue, the node proportion of the current iterative adjustment is preset, namely the preset range is obtained, the service node with the current SDK number lower than the preset threshold value in the range is selected as the service node to be adjusted, and the service node with the current uplink bandwidth higher than the average uplink bandwidth is selected as the connectable service node, so that SDK transfer can be performed, node replacement is completed, and one iterative operation is completed; and stopping iteration by carrying out iteration for multiple times until the preset time stamp is met, and finishing node adjustment.
Further, after the iteration is finished, a forced point quitting strategy is adopted for service nodes with the current SDK number and the current uplink bandwidth both lower than the corresponding preset threshold value, and the SDK in the service nodes is forced to be disconnected. In addition, for the same SDK, a merging strategy can be adopted to transfer to the same service node.
(3) And (3) SDK transfer completion node adjustment:
after receiving the adjustment request, the SDK marks the service node to be adjusted connected with the SDK, then tries to connect with the connectable service node, and acquires the data information in the service node to judge whether the connectable service node meets the use requirement, if so, the marked service node is released. In addition, when a forced back point strategy needs to be executed, the service node directly connected with the service node can be disconnected, and further, the service node can be automatically connected to the edge server to ensure the normal operation of the service.
It can be seen that, in the node adjustment method provided in this embodiment, a service parameter specified in a service node of a video stream is used as an adjustment index, and node information of a service node that needs to be adjusted in the video stream, that is, the information of the service node to be adjusted, is determined according to a preset adjustment policy for the service parameter, so that a client dynamically adjusts the corresponding service node to be adjusted based on the information, and thus, for a certain specific video stream, corresponding SDKs are concentrated into fewer nodes, thereby implementing efficient utilization of the service nodes in a system and avoiding resource waste; meanwhile, due to the fact that resource release and node adjustment are conducted on the service node of the transferred SDK, service convenience is provided for other video streams, resource waste is further avoided, and the node utilization rate is maximized.
