It is very common to provide service providers with data services to user clients via the internet. Typically, for example, multimedia service providers transmit video and audio to user clients via the internet; and the consultation service provider transmits consultation information such as texts and pictures to the user client through the Internet.
With the advent of the 5G era, bandwidth costs have become higher and higher, and therefore, bandwidth costs required to be consumed for transmitting data for user clients over mobile data networks have increased. In contrast, since the public idle bandwidth is increased, a Content Delivery Network (CDN) service technology has appeared. The edge CDN is a part of the enterprise CDN, which collects idle scattered bandwidth resources by using a technology. Specifically, a CDN service provider collects and controls resources of an edge CDN node by a technical means, so as to provide a CDN service for a user of the CDN service.
However, the existing edge CDN technology has certain drawbacks: the CDN service requires that the CDN node and the CDN service user can communicate over the internet to transmit data. However, some devices are qualified for idle storage resources, but it is difficult to transmit data based on the internet. For example, some devices do not have an external independent IP, some devices have a higher mobile data network bandwidth cost, and so on. Therefore, the prior art cannot effectively utilize the idle resources.

Detailed Description
The embodiments of the present invention will be described in further detail with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the embodiments of the invention and that no limitation of the invention is intended. It should be further noted that, for convenience of description, only some structures, not all structures, relating to the embodiments of the present invention are shown in the drawings.
Example one
Fig. 1 is a flowchart of a service implementation method for a content delivery network according to an embodiment of the present invention, where the embodiment is applicable to a case where an idle CDN node resource is effectively utilized based on interaction among a CDN service provider, a CDN node, and a CDN service user in the content delivery network, and the method can be implemented by a service implementation device of the content delivery network configured in the CDN service provider, and the service implementation device can be implemented in a hardware and/or software manner. The CDN service provider includes any computing device, such as a server, capable of providing CDN service functionality. The CDN node includes any computing device that carries a data distribution function, including but not limited to a vehicle-mounted terminal of a motor vehicle, a vehicle-mounted terminal of a shared bicycle, or a mobile device such as an intelligent terminal carried by a user. The CDN service user includes any computing device with CDN service use requirements or data access requirements, and may be a server or a mobile device, or may be a client on the device.
The CDN service provider, the CDN nodes and the CDN service use segment are used as a party for accessing the blockchain network and can be blockchain full-scale nodes or lightweight nodes. The full-magnitude node refers to a block chain network node which is deployed with deployment data of a block chain, such as an intelligent contract or a consensus mechanism, and stores all block data and transaction data; the lightweight node refers to a blockchain network node which is deployed with deployment data of a blockchain, but does not store or store part of the blockchain data and transaction data, and can participate in a transaction request interaction process of the blockchain.
As shown in fig. 1, the method for implementing a service of a content distribution network provided in this embodiment may include:
and S110, deploying data required to be transmitted by the CDN service to at least one CDN node.
The CDN service provider provides CDN service according to service deployment requirements of a CDN service user, and can pre-deploy data to be transmitted on at least one CDN node according to a pre-set data deployment strategy. The data deployment strategy can be set according to factors such as the type of data to be transmitted, the position distribution condition of the CDN node in the current environment, the available communication mode of the CDN node and the like. The data types include but are not limited to entertainment, education, current affairs, hot events, businesses, consultations and the like, the data types are different, and the corresponding data access needs are different, so that different data deployment modes can be selected. For example, if the data to be transmitted belongs to the data of the current hot event and the access demand is large, a data centralized deployment mode may be selected to deploy on all CDN nodes in a specific area; if the access requirement of the data to be transmitted is limited, the data can be selected to be deployed on part of CDN nodes in a specific area. In addition, if the distribution of CDN nodes in a specific area is more concentrated, data to be transmitted may also be deployed in batches on each CDN node in the area, and data stored on each CDN node may or may not overlap. Equivalently, each CDN node may store the data to be transmitted completely, or may selectively store a part of the data.
Alternatively, the CDN node may be a mobile device, and the mobile device includes, but is not limited to, a vehicle-mounted terminal of a motor vehicle, a vehicle-mounted terminal of a shared bicycle, or an intelligent terminal (e.g., a mobile phone, an ipad, etc.) carried by a user. By using the mobile device as a CND node, the mobility of data to be transmitted can be improved based on the mobility of the device, the data access amount can be increased, and the utilization rate of these idle resources can be further improved. Particularly, the shared bicycle-based CDN nodes benefit from the advantages of low driving speed of the shared bicycle, relatively centralized and stable distribution areas, and large number of shared bicycles, so that the data volume of transmission and the stability of data transmission can be ensured in the data transmission process with the CDN service user, and the influence of a high moving speed of the device on the data transmission quality is avoided.
And S120, when the CDN service using end needs to access the data deployed on the CDN node, determining a communication mode for data transmission between the paired CDN node and the CDN service using end.
When the CDN service using end triggers a data access requirement deployed on the CDN node through the CDN service provider, the CDN service provider determines a CDN node paired with the CDN service using end, and determines a communication mode for data transmission between the paired CDN node and the CDN service using end, so that the paired CDN node and the CDN service using end are controlled to perform data transmission by using the communication mode. Optionally, the communication mode includes a short-distance wireless communication mode or a local area network communication mode and other non-internet communication modes, such as bluetooth communication, WIFI (wireless fidelity) communication, ZigBee communication, and the like.
The short-distance wireless communication mode is a wireless communication mode supporting data transmission in a short-distance range, the power consumption and the cost are both lower, the network laying is simple, and the operation is convenient; the local area network communication method is an internal communication method between computer groups formed by interconnecting a plurality of computers in a certain area, and may be wireless transmission or wired transmission, compared with the wide area network communication, and the local area network communication method has a high transmission rate and a low cost. Therefore, in this embodiment, the short-range wireless communication mode or the local area network communication mode can be used as a free communication mode, and the network broadband cost can be reduced compared with the internet communication mode on the basis of fully utilizing idle resources.
The pairing is a verification on whether data transmission can be carried out between the CDN node and the CDN service using end based on a non-Internet communication mode supported by both the CDN node and the CDN service using end. The communication mode is generally a communication mode in which the CDN node and the CDN service user can perform peer-to-peer direct transmission. There is usually one, and preferably two or more, available communication methods, which can be used for selective pairing of different CND nodes and CDN service users.
Optionally, the determining of the communication mode for data transmission between the paired CDN node and the CDN service user includes: and determining a matched communication mode between the paired CDN node and the CDN service using end through at least one available communication mode of each CDN node and each CDN service using end which is obtained in advance.
For example, the CDN service provider may obtain an available communication method of each CDN node before deploying data to be transmitted to the CDN node or in a process of deploying the data; when a data access request of a CDN service using end to a CDN node is obtained or a CDN service using request of the CDN service using end is received, obtaining an available communication mode of the CDN service using end; certainly, in the content delivery network, each CDN node and each CDN service user may also actively report their available communication modes to the CDN service provider; then, based on the available communication modes of each CDN node and the CDN service user, the CDN service provider determines, as a matching communication mode between the CDN node and the CDN service user, a non-internet communication mode that is supported by both the CDN node that performs data transmission and the CDN service user and that can implement normal data transmission between the CDN node and the CDN service user. When various non-internet communication modes which are supported by the CDN node and the CDN service using end and can realize normal data transmission between the CDN node and the CDN service using end are available, a target communication mode can be determined according to preset communication mode selection conditions, such as signal strength, data transmission stability and the like.
Further, determining a communication mode for data transmission between the paired CDN node and the CDN service user includes:
and determining a CDN node with the position matched with the available communication mode according to the position of the CDN service using end and the available communication mode, and providing the communication mode of data transmission service. The location matching means that the CDN node and the CDN service user can perform data transmission within a preset distance range. For example, a target area may be determined by using the location of the CDN service user as a center, a CDN node that matches an available communication method of the CDN service user is determined in the target area, and then a communication method for data transmission between the CDN service user and the CDN service user is determined according to a preset communication method selection condition.
And S130, controlling the paired CDN node and CDN service using end to transmit data in a determined communication mode. That is, under the control of the CDN service provider, the CDN service consumer accesses the deployed data in the CDN node.
According to the technical scheme, the CDN service provider deploys the transmission data on at least one CDN node, and determines a communication mode for data transmission between the paired CDN node and a CDN service using end, so that the CDN service using end can access the required data from the paired CDN node through the determined communication mode, which is equivalent to a data transmission mode of paired communication between the CDN service using end and the CDN node, the problem that the utilization rate of idle resources in a content delivery network for data transmission based on the Internet is low at present is solved, the data transmission mode of the content delivery network is enriched, the utilization rate of the idle resources is improved, and the available resource amount of the content delivery network is increased.

And S220, when the CDN service using end needs to access the data deployed on the CDN node, predetermining at least one available communication mode of each CDN node and each CDN service using end through agent programs deployed on the CDN node and the CDN service using end.
In this embodiment, the CDN service provider may deploy an agent program on each CDN node and each CDN service user in advance, and manage and control the CDN nodes and the CDN service users through the agent program. For example, the CDN service provider obtains information of each CDN node and the CDN service user, such as available communication methods and location information, through the agent. Certainly, each CDN node and CDN service user may also actively report their information to the CDN service provider through the agent. The agent may be an embedded code or an independent client, and this embodiment is not limited in particular.
And S230, determining a matched communication mode between the paired CDN node and the CDN service using end in at least one available communication mode of each CDN node and each CDN service using end.
And S240, sending a communication establishing instruction and a data transmission instruction to the paired CDN node and CDN service using end respectively through agent programs deployed at the CDN node and the CDN service using end so as to control the paired CDN node and CDN service using end and perform data transmission by determining a communication mode.
For example, after a CDN service provider determines a communication mode matched between a paired CDN node and a CDN service user, the CDN service provider sends a communication establishment instruction to the CDN node and the CDN service user through an agent program, and the CDN node and the CDN service user establish a communication connection between them according to an instruction of the communication establishment instruction; then, after receiving the communication establishment success feedback fed back by the CDN node and the CDN service user, the CDN service provider sends data transmission instructions to the CDN node and the CDN service user, respectively, through the agent programs deployed at the CDN node and the CDN service user, and indicates that data transmission between the CDN node and the CDN service user is possible.
The CDN service provider sends a communication establishment instruction and a data transmission instruction, so that the CDN node and the CDN service user can be controlled to find the other side in time, establish communication at a proper time and transmit data.
On the basis of the above technical solution, optionally, the method further includes:
and if the matching condition between the paired CDN node and the CDN service using end is determined to disappear, controlling to switch a data transmission mode or switching the paired CDN node. For example, a communication fault occurs between a currently paired CDN node and a CDN service user, or a CDN node paired with the CDN service user exceeds a distance range for normal data transmission, and the like, the CDN service provider may control switching between the paired CDN node and the CDN service user to another available communication mode, or control the CDN service user to perform communication pairing with another available CDN node, so as to ensure that the CDN service user can normally access required data.
According to the technical scheme, when the CDN service using end needs to access data deployed on the CDN node, the agent programs deployed on the CDN node and the CDN service using end determine the communication mode matched between the CDN node and the CDN service using end, and control the paired CDN node and the CDN service using end to perform data transmission by using the determined communication mode through the agent programs, the problem that the idle resource utilization rate is low in a content delivery network for performing data transmission based on the Internet at present is solved, the data transmission mode of the content delivery network is enriched, the idle resource utilization rate is improved, and the available resource amount of the content delivery network is improved.
