Background
With the rapid development of internet technology, network propagation technologies such as peer to peer (P2P) are also widely used.
The P2P network is also called a peer-to-peer network, and each node in the P2P network can be used as a client to acquire data and a server to provide data for other nodes. A super node exists in a P2P Network, where the super node obtains data from a Content Delivery Network (CDN), and often thousands of files are cached on one super node. Compared with the super node, other nodes are called as common nodes. The ordinary node and the super node establish P2P connection and acquire data through P2P connection. There are multiple network lines for a super node. The upper limit of the bandwidth of each network line is fixed, and each network line is capable of providing P2P data traffic and other communication traffic. If the bandwidth occupied by the P2P data service is not controlled, when the data service volume of the P2P is large, the bandwidth of other communication services is seized, and the other communication services are affected, so that the overall quality of the service is affected.
In order not to affect the overall quality of the service, the conventional way is to control the bandwidth of P2P data traffic. For example, the nominal bandwidth of the network line is 50Mbps, limiting the bandwidth of P2P data traffic to 45 Mbps. The super node's P2P data output is limited directly when the P2P data traffic bandwidth reaches 45 Mbps. However, this bandwidth control method may cause a sudden speed drop of the super node to transmit data to the normal node, resulting in a traffic delay of the normal node, and the like.

Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
The P2P technology is also called peer-to-peer network transmission technology, and is a new communication network transmission technology that has emerged in recent years. The P2P network breaks the server/client (S/C) mode of the traditional network, and establishes a direct client-to-client communication mechanism. In a peer-to-peer network, each node can be used as a client to acquire data and also can be used as a server to provide data for other nodes. It can be seen that each node in the P2P network is in equal position. The peer-to-peer network is an extension of a distributed concept, server burden in a traditional mode is distributed to each node in the network, processing pressure of the server is greatly relieved, and meanwhile a large amount of CDN flow cost can be saved.
In the P2P network, edge devices such as tv boxes and network disks with good network quality and good hardware performance are often used as super nodes. And the super node acquires complete file data from the CDN. Other regular nodes establish P2P connections with supernodes to obtain the required data. By introducing the super nodes, the performance of various aspects of the P2P network can be improved.
Because the performance of the super node is good, a large amount of file data is often stored. For example, in short video service, a super node often stores thousands of files, and the access heat of each file is different. Meanwhile, there may be multiple network lines, also referred to as physical lines, in a super node. The nominal bandwidth (also referred to as the upper bandwidth limit) of each network line is fixed. One network line can provide P2P data services and other communication services. When the heat of a certain file stored on a super node is relatively high, if the bandwidth of the P2P data service is not limited, a large number of common nodes establish P2P connections with the super node through the same network line, and the P2P data service on the network line occupies the bandwidth of other communication services, which affects the service quality of the other communication services. Moreover, when the P2P data service occupies a large amount of bandwidth, it is very likely to trigger operator limitation, that is, the operator may reduce the rated bandwidth of the network line, reduce the quality of the network line, and the like, which causes packet loss, delay, and the like of the P2P data service, and the stability of the P2P data service is greatly reduced, which may cause that the common node cannot acquire data in a severe case. When the heat of a certain file stored on the super node is low, the network line of the super node is idle, the output bandwidth is low, and the resource utilization rate is insufficient.
In order not to affect the quality of service of other traffic, the traditional approach is to control the bandwidth of the P2P data traffic of the super node. However, the bandwidth control method may cause a sudden decrease in the speed of the super node transmitting data to the normal node, resulting in quality problems such as service delay of the normal node. For example, if the nominal bandwidth of the network line is 50Mbps, the bandwidth of the P2P data traffic is limited to 40Mbps, and if the bandwidth required by the P2P data traffic is 55Mbps, the bandwidth of the P2P data traffic is limited to 40Mbps, which results in a sudden drop in the data transmission rate of the super node to the normal node. At this time, even if there are other super nodes capable of providing resources, since the ordinary node does not access the other super nodes, the load of the currently accessed super node is relatively large, and the load of the other super nodes is relatively small. Obviously, the load of the super node is unbalanced due to the existing bandwidth control mode, and the bandwidth utilization rate is reduced after the output bandwidth of the super node is limited.
Based on this, when the management node recommends a super node for the terminal device, the management node selects a super node that has cached required resources from the plurality of super nodes, and selects a network line with a small line output bandwidth from the plurality of network lines of the super node to recommend to the terminal device, so that the P2P data service of the terminal device with the established P2P connection is not affected, and the stability of the P2P network is improved.
Fig. 1 is a schematic diagram of an implementation environment of a bandwidth control method according to an embodiment of the present application. Referring to fig. 1, the embodiment includes a management node 11, a plurality of super nodes 12, a terminal device 13, a configuration server 14, and a base server 15. Wherein, each super node 12 and the management node 11 establish a network connection, each super node 12 also establishes a network connection with the CDN server 15, and each super node 12 and the configuration server 14 establish a network connection. The terminal device 13 establishes a network connection with the management node 11. It should be noted that only one terminal device 13 connected to the super node 12 is illustrated in fig. 1. In an actual environment, the number of terminal devices 13 is larger.
The management node 11 is also referred to as a control node, a tracking (tracker) node, and the like, and is configured to manage a plurality of super nodes 12, such as nodes that identify which super nodes are full and not recommendable to the terminal device 13. For each super node 12, the management node further identifies which network lines of the super node 12 can be recommended to the terminal device, which network lines cannot be recommended to the terminal device, and the network lines that cannot be recommended to the terminal device are network lines with larger line output bandwidth. After receiving the resource query request of the terminal device 13, the management node 11 selects an appropriate super node and network line from the plurality of super nodes 12 according to the resource identifier and recommends the selected super node and network line to the terminal device 13.
The super node 12 is, for example, an edge device with relatively good network quality or hardware performance, such as a television box or a network disk. The super node 12 downloads a large amount of data from the base server 15, and when a terminal device 13 establishes a P2P connection with the super node 12, it can acquire the required data from the super node 12. The super node 12 can also obtain some parameters through the configuration server 14, and calculate the first threshold value and the second threshold value, etc. by using the parameters. The first threshold is a limit value of the line output bandwidth of the super node 12, and if the output bandwidth of a certain network line of the super node 12 is greater than or equal to the first threshold, it indicates that the network line is congested, and other terminal devices cannot establish a P2P connection with the super node 12 by using the network line.
The second threshold is a limit value of the total output bandwidth of the super node 12, and if the total output bandwidth of the super node 12 is greater than or equal to the second threshold, it indicates that the super node 12 is a full load node, and the P2P data service cannot be provided to other terminal devices.
The terminal device 13 is installed with various applications, such as a video playing application, a shopping application, a searching application, an instant messaging tool, a mailbox client, social platform software, an image processing application, and the like. The terminal device 13 may be hardware or software. When the terminal device 31 is hardware, the terminal device 31 is, for example, a mobile phone, a tablet computer, an e-book reader, a laptop portable computer, a desktop computer, or the like. When the terminal device 31 is software, it can be installed in the above listed hardware devices, in this case, the terminal device 31 is, for example, a plurality of software modules or a single software module, and the embodiment of the present application is not limited.
The configuration server 14 stores some configurable parameters, such as a nominal bandwidth of each network line of the super node, a line bandwidth threshold coefficient, a total bandwidth threshold coefficient of the super node, etc., wherein the nominal bandwidth is also referred to as a bandwidth upper limit, etc., and is usually fixed, such as 50Mbps, 100Mbps, etc. The line bandwidth threshold factor is used to calculate the first threshold mentioned above and the total bandwidth threshold factor is used to calculate the second threshold mentioned above. The total bandwidth threshold coefficient and the line bandwidth threshold coefficient are not fixed but vary according to user needs, network conditions, and the like, and thus the first threshold value and the second threshold value described above also vary.
The basic server 15 may be an independent physical server, or may be a server cluster or a distributed system formed by a plurality of physical servers, and may be a cloud server providing basic cloud computing services such as a cloud service, a cloud database, cloud computing, a cloud function, cloud storage, a web service, cloud communication, a middleware service, a domain name service, a security service, a Content Delivery Network (CDN), and a big data and artificial intelligence platform.
Next, a bandwidth control method according to an embodiment of the present application will be described in detail based on the architecture shown in fig. 1. For example, please refer to fig. 2.
Fig. 2 is a flowchart of a bandwidth control method according to an embodiment of the present application. The present embodiment is explained from the perspective of a management node. The embodiment comprises the following steps:
201. receiving a resource query request from a terminal device, wherein the resource query request carries a resource identifier.
Illustratively, a user opens a video playing application on the terminal device, clicks a video to be watched on an interface of the video playing application, and triggers the terminal device to send a resource query request carrying a resource identifier to the management node. For example, if the user clicks on a series a, the resource is identified as the series name, lead actor, year, etc. of the series a.
202. A first node is determined from a plurality of super nodes.
The first node is a node which caches the resource indicated by the resource identification in the plurality of super nodes.
In the embodiment of the present application, a super node has a plurality of network lines, which are also referred to as physical lines, and a plurality of network lines are led out from the super node, where each network forms the network line described in the embodiment of the present application.
And the management node determines the super node of the resource indicated by the cached resource identifier according to the resource identifier. For example, if the user clicks tv series a, the resource identifier is the series name, lead actor, year, etc. of tv series a, and the first node is a super node in which tv series a is cached. And if a plurality of super nodes of the resources indicated by the cached resource identifiers exist, randomly selecting one super node from the super nodes as the first node. Alternatively, the node having the smallest total output bandwidth is taken as the first node. For each super node, the total output bandwidth is the sum of the line output bandwidths of the respective network lines of that super node. Line out bandwidth is the bandwidth that has been consumed by the network line. For example, a super node has 4 network lines, and the line output bandwidths are 45Mbps, 20Mbps, 30Mbps, and 30Mbps, respectively, then the total output bandwidth of the super node is 125 Mbps.
203. A first network line is determined from a plurality of network lines of the first node, wherein the first network line is a network line of the plurality of network lines, and the line output bandwidth of the first network line is smaller than a first threshold value.
After the management node determines the first node, the line output bandwidth of each network line of the first node is further determined. And then, taking the network line with the line output bandwidth smaller than the first threshold value as the first network line. When there are a plurality of network lines whose line output bandwidths are smaller than the first threshold, one network line is randomly selected as the first network line, or the network line whose line output bandwidth is the smallest is selected as the first network line.
204. And sending a resource inquiry response for indicating the first network line to the terminal equipment.
Correspondingly, the terminal equipment receives the resource inquiry response. Then, the terminal device establishes P2P connection with the first node through the first network line of the first node, and acquires the resource indicated by the resource identifier from the first node.
In the bandwidth control method provided by the embodiment of the present application, after receiving a resource query request, which carries a resource identifier, of a terminal device, a management node determines a first node of a resource indicated by a cached resource identifier from a plurality of super nodes, and further determines a first network line, of which line output bandwidth is smaller than a first threshold, from a plurality of network lines of the first node. Then, the management node recommends the first network line of the first node to the terminal device, so that the terminal device establishes a P2P connection with the first node through the first network line of the first node, and acquires the resource indicated by the resource identifier from the first node. By adopting the scheme, when the management node determines the super node recommended to the terminal equipment, the super node with the cached required resources is selected from the super nodes, and the network line with the small line output bandwidth is selected from the network lines of the super node and recommended to the terminal equipment, so that the P2P data service of the terminal equipment with the established P2P connection is not influenced, the bandwidth stable output of each super node is maintained, and the stability of the P2P network is improved.
Fig. 3 is a flowchart of a bandwidth control method according to an embodiment of the present application. The present embodiment is explained from the perspective of interaction between a management node and a super node. The embodiment comprises the following steps:
301. the second node determines a line output bandwidth for each of the plurality of network lines.
Wherein the second node is any one of a plurality of super nodes managed by a management node.
In the embodiment of the present application, the management node manages a plurality of super nodes, and hereinafter, any one of the plurality of super nodes is referred to as a second super node. The second node reports the line output bandwidth, the total output bandwidth and the like to the management node regularly.
In this step, the second node periodically calculates a line output bandwidth of each of the plurality of network lines.
302. And determining whether a second network line is a recommendable line according to the line output bandwidths of the plurality of network lines and a first threshold, wherein the second network line is any one of the plurality of network lines.
Illustratively, the second node compares the current line out bandwidth of each network line to the first threshold to determine whether the line out bandwidth of the second network line is greater than or equal to the first threshold. If the line output bandwidth of the second network line is greater than or equal to the first threshold, the second network line is an unrenderable line; if the line output bandwidth of the second network line is less than the first threshold, the second network line is a recommendable line.
303. The second node sends the first indication information to the management node.
Correspondingly, the management node receives first indication information, and the first indication information is used for indicating whether the second network line is a recommendable line.
304. And the management node identifies the second network line according to the first indication information.
Illustratively, the management node stores a correspondence between a line identifier of a network line of each super node and a recommended identifier, and when the recommended identifier is 0, it indicates that a line output bandwidth of the network line corresponding to the line identifier is smaller than a first threshold, where the network line is a network line that can be recommended to the terminal device. When the recommended mark is 1, the line output bandwidth of the network line corresponding to the line mark is greater than or equal to a first threshold, and the network line is a network line which cannot be recommended to the terminal device.
Initially, the line output bandwidth of each network line is less than a first threshold by default, that is, the recommended identifier corresponding to each line identifier is 0. And then, after receiving the first indication information each time, the management node updates the recommended identifier of the second network line according to the first indication information.
In the bandwidth control method provided in the embodiment of the application, the second node periodically sends, to the management node, first indication information for indicating whether the second network line is a recommendable line, so that the management node identifies the second network line according to the first indication information, and does not recommend the second network line with a larger bandwidth to the terminal device, thereby ensuring that the P2P data service of the terminal device that establishes the P2P connection with the second node through the second network line is not interfered, and improving the stability of the P2P network and the service quality of the P2P data service.
Optionally, in the foregoing embodiment, after determining the line output bandwidth of each of the plurality of network lines of the second node, the second node further determines a total output bandwidth of the plurality of network lines, and determines, according to the total output bandwidth and a second threshold, whether the second node is a node that can receive the resource cache request, so as to obtain the second indication information. And then, the second node sends second indication information to the management node, wherein the second indication information is used for indicating whether the second node can receive the resource cache request.
Illustratively, the second node periodically determines a line output bandwidth of each of the plurality of network lines, and obtains a total output bandwidth from the line output bandwidth of each of the network lines. And then, the second node compares the total output bandwidth with a second threshold value to obtain second indication information and sends the second indication information to the management node. After receiving the second indication information, the management node identifies the super nodes with the total output bandwidth larger than or equal to a second threshold as the super nodes which can not receive the resource cache request and can not recommend the resource cache request to the terminal equipment; and identifying nodes with the total output bandwidth smaller than a second threshold value as receivable resource cache requests.
Then, after the management node receives the resource query request of the terminal device, if a first node exists in the plurality of super nodes, that is, a node that has the resource indicated by the cached resource identifier exists, and a first network line with a smaller line output bandwidth exists in the plurality of network lines of the first node, the first network line of the first node is recommended to the terminal device. For example, the resource identifier indicates a series a, and the resource of the series a is stored on the first node.
After receiving a resource query request of the terminal device, the management node does not have a node of the resource indicated by the cached resource identifier if the first node does not exist in the plurality of super nodes; or, even if the first node exists, when the first network line with smaller line output bandwidth does not exist in the plurality of network lines of the first node, the management node sends a resource caching request to the third node, and sends a resource query response for indicating the third node to the terminal device. And after receiving the resource caching request, the third node acquires and caches the resource indicated by the resource identifier from the CDN and the like, wherein the third node is a node of which the total output bandwidth is smaller than a second threshold value in the plurality of super nodes. And after receiving the resource query response, the terminal equipment sends a resource request to the third node. And after receiving the resource request carrying the resource identifier, the third node sends a resource response carrying the resource indicated by the resource identifier to the terminal equipment.
For example, the resource identifier carried by the resource query request sent by the terminal device to the management node indicates a tv series B, and the management node finds that a node where the resource of the tv series a is cached exists in the plurality of super nodes, but the super node where the resource of the tv series B is cached does not exist, and then the management node sends a resource caching request to a third node with a smaller total output bandwidth.

Wherein, the statistical duration is the preset duration. Then, the second node outputs data flow D according to each time pointline_data_tCounting the time length TdurationAnd the statistical starting time point time _ start and the ending time point time _ end determine the line output bandwidth Vline_bandwidth.
