background

In the prior art, a Content Delivery Network (CDN) is adopted to realize video data delivery, so that a client can obtain requested video data for playing, storing, or the like. A conventional content delivery network generally uses a server of an IDC room as a node of a content CDN. The server of the IDC machine room is used as a node for content distribution, although the service is relatively stable, the number of the nodes is small, and the generated bandwidth cost is high, so that the cost of video service is high, and the phenomenon of blocking is easy to occur.

In order to save cost, shared computing is now applied in CDNs for video services, i.e. a shared node is introduced to provide content delivery services. These shared nodes are deployed at the edge of the network for storing and distributing video data, and these nodes have a low service cost, and are generally called low-cost nodes. In an application scenario of shared computing, an application program deployed on a client obtains part of data originally provided by a traditional CDN from a plurality of low-cost nodes (such as intelligent hardware) through peer-to-peer transmission, so as to achieve the purpose of saving part of bandwidth. Currently, the scheduling system is responsible for allocating nodes to all applications meeting the requirements, and the nodes meeting the network conditions are allocated according to the sequence of arrival of requests of application nodes.

In the above allocation strategy, there are many disadvantages in allocating nodes based on the order of arrival of the application node requests: the high-quality nodes may be used up first, so that only the low-quality nodes can be used by the subsequent application programs, and the node distribution is unbalanced.

Detailed Description

the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In the prior art, a scheduling system is responsible for allocating nodes to all applications meeting requirements, and the nodes meeting network conditions are allocated according to the sequence of arrival of requests of application nodes. Under the allocation strategy, the high-quality nodes may be used up first, so that the application programs in the later sequence can only use the nodes with slightly poor quality, and the node allocation is unbalanced.

therefore, the embodiment of the application discloses a node allocation method, which avoids that high-quality nodes are allocated early and improves the balance of node allocation.

Referring to fig. 1, a node allocation method disclosed in the embodiment of the present application includes:

S11: acquiring a request for applying for a node;

in this step, a request for applying for a node is obtained, where the request may be a request initiated by an application program, and the node may specifically be an intelligent hardware device, and the intelligent hardware device may be a personal storage device (such as a guest playing cloud, a money making device, and the like), an intelligent television, a television box, a network storage device (NAS), a router, and the like.

s12: determining an initiator of the request, and acquiring historical node use information of the initiator;

After a request for applying for a node is obtained, an initiator of the request is further determined, and the use information of the initiator history for the node is obtained.

specifically, the process of obtaining the historical node usage information of the initiator may specifically include: acquiring network characteristic information of an initiator and node characteristic information of a history node used under the current network characteristic; the node characteristic information includes but is not limited to the connection power and/or the service goodness of the node, and also includes whether a UPNP mapping exists; the network characteristic information includes but is not limited to the type of NAT located, geographical location information, operator information, and the like.

It can be understood that, in this embodiment, after the network feature information of the initiator and the node feature information of the history node used under the current network feature are obtained, the network feature information and the node feature information may also be subjected to association recording, so that after a subsequent request of another application node is obtained, the history node use information of the request initiator does not need to be obtained again, and the node feature information of the required node may be determined directly according to the network feature information of the request initiator.

s13: determining a pre-allocation node which is allocated for data corresponding to the request in advance based on node available information;

It should be noted that, in this embodiment, a node is pre-allocated in advance, specifically, data corresponding to the request may specifically be video stream data, and this embodiment may first determine all nodes to be allocated for providing services, and determine whether the nodes to be allocated are available, so as to obtain node availability information; and determining a corresponding pre-distribution node for each video stream according to the node available information and the heat degree of the data, wherein the data can be video stream data, namely determining the corresponding pre-distribution node for each video stream according to the node available information and the heat degree of the video stream.

correspondingly, in this embodiment, after the request for applying for the node is obtained, the video stream information corresponding to the current request is obtained, so as to determine the node corresponding to the video stream in the pre-allocated node.

s14: determining the target node quality and a preset proportion corresponding to each target node quality according to the historical node use information;

In this embodiment, when determining the quality of the target node according to the historical node usage information, the nodes may be specifically divided into three qualities, i.e., high, medium, and low, and when selecting the target node from the pre-allocation nodes to allocate to the initiator according to the historical node usage information, the quality of the target node and the preset proportion corresponding to the quality of each target node may be determined according to the historical node usage information.

In a specific implementation, after obtaining parameters for characterizing the service quality, such as a node connection success rate, a service goodness rate, and the like, when the target node provides a service for an application before obtaining the target node, an evaluation value for the service quality of the node may be determined based on the parameters for characterizing the service quality, specifically, a weighted value may be calculated by using a specific numerical value of each of the parameters and a corresponding preset weight, and the weighted value is used as the evaluation value of the service quality of the node. In this embodiment, two or more thresholds may be preset, and the node service quality may be divided into multiple levels by using multiple thresholds. For example, a first threshold value and a second threshold value may be set in advance, where the first threshold value is smaller than the second threshold value, the node service quality is classified into three levels of high, medium, and low by the first threshold value and the second threshold value, that is, a quality level corresponding to a node having a service quality evaluation value lower than the first threshold value is determined to be low, a quality level corresponding to a node having a service quality evaluation value between the first threshold value and the second threshold value is determined to be medium, and a quality level corresponding to a node having a service quality evaluation value higher than the second threshold value is determined to be high. After the evaluation value of the service quality of the node corresponding to the current node is determined, the range of the current evaluation value can be determined by comparing the evaluation value of the current node with the first threshold and the second threshold, and then the service quality grade corresponding to the current node is determined. The preset weight, the first threshold value and the second threshold value may be set according to circumstances in specific implementations, and the present invention is not limited to this.

It will be appreciated that the preset ratio may be a ratio preset by the system, or may be a ratio manually set during implementation. By allocating nodes of each quality to the request of the current application node, the possibility that all the nodes of all the qualities can be used is ensured, and the nodes are prevented from being omitted. In addition, in this embodiment, for a node with poor service quality, it may be disabled first and retried after a period of time.

S15: determining the number of target nodes according to the preset proportion;

specifically, in this step, the number of target nodes corresponding to the quality of each target node may be determined according to the total number of nodes required by the request of the currently applied node and the preset ratio corresponding to the quality of each target node.

S16: and selecting a target node from the pre-distribution nodes to distribute to the initiator based on the quality of the target node and the corresponding quantity of the target nodes.

As a preferred embodiment, when selecting a target node from the pre-allocated nodes to allocate to the initiator based on the quality of the target node and the number of the corresponding target nodes, this embodiment may first obtain a random sequence including all the pre-allocated nodes, so that the target node may be selected from the random sequence to allocate to the initiator based on the quality of the target node and the number of the corresponding target nodes, and the scheduling performance of the node when applying for is ensured. It can be understood that, in the node allocation process, if the total number of nodes corresponding to the quality of any one of the required target nodes is smaller than the number of the target nodes, the target nodes corresponding to the qualities of other nodes are selected until the number of the target nodes is met. For example, if the number of required high-quality nodes is 30 and the number of high-quality nodes in the corresponding pre-allocated nodes is 20, 10 nodes are selected from the high-quality nodes to meet the requirement of the number of nodes.

further, in order to prevent data from not being updated for a long time, the embodiment may monitor the recorded network characteristic information and node characteristic information; and if the network characteristic information and the node characteristic information are not updated after exceeding a preset time period, generating overtime reminding information.

according to the above scheme, the node allocation method provided by the application includes: acquiring a request for applying for a node; determining an initiator of the request, and acquiring historical node use information of the initiator; determining a pre-allocation node which is allocated for data corresponding to the request in advance based on node available information; determining the quality of the nodes to be distributed and a preset proportion corresponding to the quality of each node to be distributed according to the historical node use information; determining the number of nodes to be distributed according to the preset proportion; and selecting a target node from the pre-distribution nodes to distribute to the initiator based on the quality of the nodes to be distributed and the corresponding quantity of the nodes to be distributed. According to the method, the corresponding pre-distribution nodes are distributed for different data in advance based on the node available information, after the request for applying the nodes is obtained, the historical node use information of the request initiator is obtained, the quality and the corresponding proportion of the nodes to be distributed are further determined according to the historical node use information, the number of the nodes to be distributed is determined according to the proportion, the target nodes with the corresponding number are dynamically selected from the pre-distribution nodes to be distributed to the request initiator, the condition that high-quality nodes are distributed too early when the distribution is carried out only according to the sequence of the request is avoided, and the balance of node distribution is improved.

fig. 2 is an overall flowchart of a specific node allocation method according to an embodiment of the present application. As shown in fig. 2, the present embodiment collects data reported by a node, such as network information and a use condition, where the use condition specifically refers to how much traffic and bandwidth are used and which application program the node has served for; and collecting information when the application program requests the nodes from the scheduling, wherein the information comprises data flow information and the use condition of the historical distributed nodes. And then nodes are pre-distributed based on the node information and the video stream information, each video stream comprises nodes with various characteristics, and the nodes are selected from the pre-distributed nodes when the nodes are applied in the later period.

in this embodiment, the nodes are summarized to the corresponding network characteristics according to the node information and the information when the application program applies to the scheduling request node to obtain the node service quality data, the available node characteristics are selected from the node service quality data according to the characteristics of the application program applying the node each time, and the node finally providing the service is selected from the pre-allocated nodes according to the service qualities of different characteristics.

it can be understood that, because a large number of applications are in various complex network environments, the nodes have different service qualities for different applications, and it is only one-sidedly inaccurate to evaluate the quality of the nodes according to the historical use conditions of the nodes.

In the following, a node distribution system provided by an embodiment of the present application is introduced, and a node distribution system described below and a node distribution method described above may be referred to each other.
