Description

Method, device, equipment and storage medium for realizing service of content distribution network

Technical Field

The embodiment of the invention relates to the technical field of network data transmission, in particular to a service implementation method, a device, equipment and a storage medium of a content distribution network.

Background

Service providers providing services have become very popular to provide data services to user clients via the internet. Typically, for example, multimedia service providers transmit video and audio to user clients via the internet; the information service provider transmits 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 a defect that an edge node is a third party and is not a device owned by a CDN service provider, and a service provider collecting edge node resources is only responsible for deploying the technology to the edge node, but does not have an operation and maintenance right for the deployed edge node, which brings a hidden danger. The edge node can maliciously tamper the data to be transmitted deployed on the edge node, so that the data are distributed by means of a channel of a CDN service user, and adverse effects are brought.

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, which may be applied to combine a content delivery network with a blockchain network, and prevent data from being tampered during data transmission based on multi-party cooperation among a CDN service provider, a CDN edge node, and a CDN service consumer.

The method may be performed by a service implementation apparatus of a content distribution network configured with blockchain nodes, which may be implemented in hardware and/or software, and may be integrated in a computing device carrying the blockchain nodes.

The block chain link point executing the technical scheme of the embodiment may be a full-scale node or a lightweight node. 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.

The CDN service provider includes any computing device capable of providing CDN service functions, and is mainly used for aggregation, control and coordinated scheduling of services for CDN edge node resources, for example, a server is used to perform the functions. The CDN edge node includes any computing device carrying a data distribution function, and may be a fixed device or a mobile device, where 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 carried by a user. The CDN edge node may be a large computing device, or may be a small terminal device. The CDN service user includes any computing device that has a CDN service deployment requirement, for example, a server that needs to deploy a part of data and obtain the data again when needed, such as a multimedia service provider, deploys the multimedia data to the CDN edge node, and then pulls the data from the CDN edge node when needed by the client. The CDN service provider, the CDN edge node and the CDN service user are used as one party for accessing the blockchain network and can be a blockchain full-scale node or a lightweight node.

As shown in fig. 1, the service implementation method of the content distribution network provided in this embodiment may include:

and S110, receiving a data fingerprint uploading transaction request initiated by a CDN service user of the content delivery network, and transmitting and storing the data fingerprint uploading transaction request in the blockchain network.

When a CDN service user generates a CDN service deployment requirement (or referred to as a data deployment requirement), for example, specified data needs to be deployed in a CDN edge node by a CDN service provider, the CDN service user calculates a data fingerprint of the data to be deployed, and transmits the data fingerprint to a blockchain network in the form of a data fingerprint upload transaction request, so that each blockchain node can store the data fingerprint, and data in a data transmission process can be checked and verified subsequently by using the data fingerprint. When the CDN service user sends the data fingerprint, the data fingerprint may also be sent together with the data identifier of the data to be deployed. And then, the CDN service user sends the data to be deployed to the CDN service provider in the form of a data deployment request through communication interaction with the CDN service provider. The data deployment request may include a data fingerprint calculated by the CDN service user.

And S120, receiving an authentication transaction request of data corresponding to the data fingerprint initiated by the CDN service provider, transmitting and storing the authentication transaction request in the blockchain network, wherein the data is deployed at a CDN edge node by the CDN service provider.

After receiving a data deployment request of a CDN service user, a CDN service provider needs to authenticate data to be deployed. The authentication process may be performed by a CDN service provider, and is configured to authenticate the authenticity and validity of data, carry a result of whether authentication passes or not (i.e., authentication information) in the authentication transaction request, and transmit the result to the blockchain network, for example, the CDN service provider may perform all audit authentication or random check audit authentication on the data to be deployed according to a preset data audit rule, and generate corresponding authentication information to be carried in the authentication transaction request and transmit the authentication information to the blockchain network after the authentication passes. Or, the authentication process may also be performed by the blockchain network, that is, the CDN service provider may initiate an authentication transaction request for the data to the blockchain network, verify the authenticity and validity of the currently received data to be deployed, carry all or part of the content of the data to be deployed in the authentication transaction request, request the blockchain network to perform authentication based on a rule set for an intelligent contract, and store and feed back an authentication result.

Optionally, the CDN service provider may further calculate a data fingerprint of the data to be deployed, and send the currently calculated data fingerprint to the blockchain network in the form of an authentication transaction request, so as to store the data fingerprint or verify the data fingerprint, thereby implementing an audit verification on the data to be deployed.

In addition, the CDN service provider may also obtain a data fingerprint from the data deployment request of the CDN service user, compare the data fingerprint with the currently calculated data fingerprint to authenticate the data to be deployed, generate authentication information if the authentication passes, and send the authentication information to the blockchain network in the form of an authentication transaction request, so that each blockchain link point may store the authentication information for use when needed.

In the current stage, if the data to be deployed pass the auditing and authenticating, the CDN service provider sends the data to the CDN edge node through communication interaction with the CDN edge node so as to complete data deployment; if the auditing authentication is not passed, the CDN service provider can refuse to deploy the data to be deployed, namely the propagation of the data to be deployed is terminated.

The data fingerprint uploading transaction request initiated by the CDN service user and the authentication transaction request for the data corresponding to the data fingerprint initiated by the CDN service provider may be transaction requests that need to be processed continuously, for example, a notification that the block chain triggers the authentication transaction request is provided to the CDN service provider in the process of processing the data fingerprint uploading transaction request, so as to trigger auditing and authentication of the data to be deployed. Of course, both may also be independently executed transaction requests.

S130, receiving a fingerprint verification transaction request of data initiated by the CDN edge node, verifying and feeding back the data based on the data fingerprint stored in the block chain.

After receiving the data to be deployed sent by the CDN service provider, the CDN edge node initiates a fingerprint verification transaction request of the data to the blockchain network, so that the authenticity and the validity of the currently received data are determined through the verification of the data fingerprint. Optionally, the CDN edge node calculates a data fingerprint of the currently received data according to the currently received data, and transmits the calculated data fingerprint to the blockchain network, where the calculated data fingerprint is carried in a fingerprint verification transaction request, so that the blockchain link point verifies the currently received data fingerprint based on the data fingerprint already stored in the blockchain, and then feeds back the verification result to the CDN edge node.

If the current block link point confirms that the received data fingerprint is consistent with or matched with the stored data fingerprint, it indicates that the data received by the CDN edge node is real, that is, the data belongs to data that the CDN service user wants to deploy through the CDN service, otherwise, the data received by the CDN edge node may be tampered. The CDN edge node determines whether to store the received data according to the received data fingerprint verification result, for example, if the data fingerprint verification is consistent or matched, the data to be deployed is stored to the local, otherwise, the storage is abandoned.

Certainly, the CDN edge node may also carry all or part of the content of the currently received data in the fingerprint verification transaction request to request the blockchain network to perform data fingerprint verification based on a rule set for an intelligent contract, and store and feed back an authentication result.

Optionally, the method further includes:

and receiving a use verification transaction request initiated by the CDN edge node, and feeding back data fingerprints and authentication information of data to the CDN edge node so that the CDN edge node can verify according to locally pre-stored data.

The CDN edge node may directly access the data fingerprint and the authentication information of the data to be deployed stored in the blockchain network, or may obtain the data fingerprint and the authentication information in a form of initiating a use verification transaction request to the blockchain network. For example, the CDN edge node may send a use verification transaction request to the blockchain network through an agent program deployed on the CDN service provider, where the agent program obtains a data fingerprint and authentication information of data to be deployed, which are fed back by the blockchain node, and the agent program obtains local data of the CDN edge node, calculates the data fingerprint, compares the data fingerprint with the data fingerprint obtained from the blockchain network, and performs audit verification on the local data of the CDN edge node in combination with the obtained authentication information. The agent program can be a piece of embedded code or an independent client. And the CDN service provider manages and controls the CDN edge nodes through a deployed agent program. In addition, the CDN service provider may also implement management and control on the CDN service consumer by using an agent deployed on the CDN service consumer.

The technical scheme of this embodiment receives a data fingerprint uploading transaction request initiated by a CDN service user through a blockchain node, so that the data fingerprint is transmitted and stored in a blockchain network, then determines an audit authentication result of data to be deployed received by the CDN service provider from the CDN service user by receiving a data authentication transaction request initiated by the CDN service provider, and finally realizes audit verification of data received by a CDN edge node from the CDN service provider by receiving a data fingerprint authentication transaction request initiated by the CDN edge node and feeds back the verification result to the CDN edge node, so that mutual constraints among the CDN service user, the CDN service provider, and the CDN edge node are realized through a blockchain in a data transmission process, and it is avoided that transmission data is tampered by any party because data falsification is present in any party and data is found in a next stage of data transmission, therefore, the problem of low data credibility caused by the risk of tampering the data in the existing content distribution network is solved, and the data credibility of multi-party operation of the content distribution network is improved.

Example two

Fig. 2 is a flowchart of a service implementation method of a content distribution network provided in the second embodiment of the present invention, and the present embodiment is further optimized and expanded based on the above embodiments. As shown in fig. 2, the method may include:

s210, receiving a data fingerprint uploading transaction request initiated by a CDN service user of the content delivery network, and transmitting and storing the data fingerprint uploading transaction request in the blockchain network.

S220, in the process of executing the data fingerprint uploading transaction request, calling an intelligent contract to generate an authentication notification, and sending the authentication notification to the CDN service provider to instruct the CDN service provider to generate the authentication transaction request according to the authentication notification.

The intelligent contract is a code segment which is written based on a plug-in mechanism and can be called and executed by nodes in a block chain network, and the execution of one intelligent contract can realize at least one function or process a class of transaction requests; the block chain can be pre-appointed during the creation and stored in the created block; or dynamically added in the creation process of the block chain and stored in a certain block; or may be stored locally at a block link point independently of the block chain. The block chain node can be used for deploying a plurality of intelligent contracts, and different intelligent contracts can correspond to different functions. When the data fingerprint uploading transaction request is executed, the block link point of the scheme of the embodiment can call an intelligent contract corresponding to a data authentication function, generate an authentication notification, and instruct a CDN service provider to generate an authentication transaction request according to the authentication notification, so that the CDN service provider can check and authenticate received data to be deployed at an appropriate time, thereby implementing data authentication control on the CDN service provider by using a block link network and contributing to improving the credibility of transmission data of a content delivery network. Meanwhile, the authentication notification also restricts the CDN service provider from authenticating the data, and the subsequent CDN service user can use the data service when the subsequent CDN service user wants to use the data service.

And S230, receiving an authentication transaction request of data corresponding to the data fingerprint initiated by the CDN service provider, transmitting and storing the authentication transaction request in the blockchain network, wherein the data is deployed at a CDN edge node by the CDN service provider.

S240, receiving a fingerprint verification transaction request of data initiated by the CDN edge node, verifying and feeding back the data based on the data fingerprint stored in the block chain.

In the technical solution of this embodiment, during the process of executing the data fingerprint upload transaction request by the blockchain node, calling an intelligent contract to generate an authentication notice, instructing a CDN service provider to generate an authentication transaction request of data to be deployed according to the authentication notice, realizing data authentication control on the CDN service provider by using a block chain network, then verifying the transaction request by receiving a data fingerprint initiated by a CDN edge node, the data received by the CDN edge node from the CDN service provider is verified and verified, mutual constraint among the CDN service user, the CDN service provider and the CDN edge node through a block chain in the data transmission process is achieved, the transmitted data is prevented from being tampered by any party, the problem that the data credibility is low due to the fact that the data in the existing content distribution network is tampered, and the data credibility of multi-party operation of the content distribution network is improved.

EXAMPLE III

and S310, receiving a data fingerprint uploading transaction request initiated by a CDN service user of the content delivery network, and transmitting and storing the data fingerprint uploading transaction request in the blockchain network.

And S320, receiving an authentication transaction request of data corresponding to the data fingerprint initiated by the CDN service provider, transmitting and storing the authentication transaction request in the blockchain network, wherein the data is deployed at a CDN edge node by the CDN service provider.

S330, in the process of executing the authentication transaction request, calling an intelligent contract to generate a deployment verification notice, and sending the deployment verification notice to the CDN edge node to indicate the CDN edge node to generate a fingerprint verification transaction request according to the deployment verification notice.

The deployment verification notice is generated by calling the intelligent contract, so that the CDN edge node can check and verify the received data at a proper time, the data verification control of the CDN edge node by using the block chain network is realized, and the credibility of the transmitted data of the content delivery network is improved.

Certainly, the block link node executing the technical solution of this embodiment may continue to invoke the intelligent contract to generate the deployment verification notification after invoking the intelligent contract to generate the authentication transaction request according to the authentication notification, so as to instruct the CDN edge node to generate the fingerprint verification transaction request according to the deployment verification notification, that is, both data verification timings of the CDN service provider and the CDN edge node may be controlled in the executing process of the solution.

S340, receiving a fingerprint verification transaction request of data initiated by the CDN edge node, verifying and feeding back the data based on the data fingerprint stored in the block chain.

The technical solution of this embodiment receives a data authentication transaction request initiated by a CDN service provider through a blockchain node, auditing and verifying the data to be deployed received by the CDN service provider from the CDN service user, meanwhile, in the process of executing the authentication transaction request of the data to be deployed, calling an intelligent contract to generate a deployment verification notice, instructing the CDN edge node to generate a fingerprint verification transaction request according to the deployment verification notice, the CDN service user, the CDN service provider and the CDN edge node are mutually constrained through the block chain in the data transmission process, data verification control of the CDN edge node by using the block chain network is realized on the basis of avoiding the effect that transmission data is distorted by any party, the problem that data credibility is low due to the fact that data in the existing content distribution network is distorted is solved, and data credibility of multi-party operation of the content distribution network is improved.

Example four

Fig. 4 is a flowchart of a service implementation method for a content delivery network according to a fourth embodiment of the present invention, where this embodiment is applicable to combining a content delivery network with a blockchain network, and is performed in cooperation with the service implementation method for a content delivery network applied to a blockchain node in the foregoing embodiment, based on multi-party cooperation among a CDN service provider, a CDN edge node, and a CDN service consumer, to prevent data from being tampered during data transmission.

The method can be executed by a service implementation device of a content delivery network configured on a CDN service user, where the service implementation device can be implemented in a hardware and/or software manner, and can be integrated with any computing device having a CDN service deployment requirement, for example, a server that needs to deploy a part of data and reacquires when needed, such as a multimedia service provider, deploys multimedia data at a CDN edge node, and then pulls the data from the CDN edge node when a client needs it.

The CDN edge node includes any computing device bearing a data distribution function, and may be a fixed device or a mobile device, where 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 carried by a user. The CDN edge node may be a large computing device, or may be a small terminal device. The CDN service provider includes any computing device capable of providing CDN service functions, and is mainly used for aggregation, control and coordinated scheduling of services for CDN edge node resources, for example, a server is used to perform the functions. The CDN service provider, the CDN edge node and the CDN service user are used as one party for accessing the blockchain network and can be a blockchain full-scale node or a lightweight node.

As shown in fig. 4, the service implementation method of the content distribution network provided in this embodiment may include:

s410, when a CDN service deployment requirement is generated, calculating a data fingerprint according to data to be deployed, initiating a data fingerprint uploading transaction request to a block chain network, and storing the data fingerprint in an uplink.

When a CDN service user generates a CDN service deployment demand, a data fingerprint of data to be deployed is calculated firstly, and then the data fingerprint is transmitted to a blockchain network in a form of uploading a transaction request of the data fingerprint, so that each blockchain link point can store the data fingerprint. The data fingerprint can be used for auditing and verifying the authenticity and the validity of the data to be deployed in the data transmission process.

And S420, transmitting the data to a CDN service provider to request authentication and deploy the data to a CDN edge node.

Illustratively, the CDN service using direction sends a CDN service deployment requirement to a CDN service provider, and sends data to be deployed to the CDN service provider, and the CDN service provider performs all audit authentication or random audit authentication on the data to be deployed according to a preset data audit rule, and carries an authentication result in an authentication transaction request to transmit the authentication result to the blockchain network. And if the data to be deployed passes the authentication, deploying the data to the CDN edge node.

And S430, when the CDN service use requirement is generated, sending a data transmission request to the CDN edge node to request the CDN edge node to provide the data transmission service.

When a CDN service user generates a CDN service use demand (or referred to as a data access demand), a data transmission request is sent to a CDN edge node where demand data is deployed, and the CDN edge node transmits local data to the CDN service user in response to the data transmission request. Further, after receiving the data sent by the CDN service provider, the CDN edge node may calculate a fingerprint of the data, and verify authenticity and validity of the currently received data by fingerprint comparison based on the fingerprint of the data stored in the blockchain network, so that the data that passes the verification is transmitted to the CDN service user in response to a data transmission request of the CDN service user. The CDN edge node transmits the data to a CDN service user, which may generally be transmitted to a client controlled by the CDN service user, for example, a server of a multimedia service provider serves as a user to perform data deployment; the deployed data is subsequently provided to a client installed in the user terminal by the multimedia service provider. Under the control of a CDN service user, a CDN edge node can directly transmit data to a terminal provided with a client.

In the technical scheme of the embodiment, a CDN service user sends a data fingerprint of data to be deployed to a block chain network for data auditing and verification in a data transmission process; the CDN service provider deploys the data passing the auditing authentication on CDN edge nodes; when a CDN service user generates a CDN service use requirement, access data can be obtained from a CDN edge node, namely, mutual constraint among the CDN service user, a CDN service provider and the CDN edge node through a block chain is realized in a data transmission process through the combination of the block chain network and a content distribution network, the phenomenon that transmission data is tampered by any party is avoided, the problem that data is low in credibility due to the fact that data in the existing content distribution network is tampered, and the data credibility of multi-party operation of the content distribution network is improved.

EXAMPLE five

Fig. 5 is a flowchart of a service implementation method of a content distribution network provided in the fifth embodiment of the present invention, and this embodiment is further optimized and expanded based on the foregoing embodiment. As shown in fig. 5, the method may include:

and S510, when a CDN service deployment requirement is generated, calculating a data fingerprint according to data to be deployed, initiating a data fingerprint uploading transaction request to a block chain network, and storing the data fingerprint in an uplink.

And S540, providing the data fingerprint of the data to the client to instruct the client to calculate the data fingerprint according to the transmission data, and comparing and verifying the data fingerprint with the provided data fingerprint.

In this embodiment, a client of the CDN service user needs to send a data transmission request to the CDN edge node through the CDN service user, but the client may directly perform data transmission with the CDN edge node. For example, a client sends a data access request to a CDN service user, the CDN service user determines, through a CDN service provider, a CDN edge node where data to be accessed by the client is deployed, and forwards the data access request of the client to the CDN edge node, and then the CDN edge node transmits data to the client in response to the data access request. The determination of the CDN edge node location where the data that the client needs to access is deployed may be determined by association between current data that needs to access and historical access data, or may be determined by an edge p2p (peer-to-peer) network discovery algorithm, or may be determined based on other transmission protocols that do not pass through a CDN service provider, for example, a CDN service user accesses any node and initiates network discovery by the node to determine a needed CDN edge node, which is not specifically limited in this embodiment.

The client can directly acquire the data fingerprint from the CDN service user, so that the data fingerprint of the transmission data can be calculated in the process of receiving the data sent by the CDN edge node, and the authenticity and the validity of the currently transmitted data can be verified by comparing the data fingerprint with the data fingerprint acquired in advance. If the fingerprint comparison is not consistent or matched, the client may refuse to receive the data sent by the CDN edge node.

Of course, if the client has the capability of accessing the blockchain, for example, if the client is configured with a lightweight node, the client can also directly acquire the data fingerprint from the blockchain for verification.

In the technical scheme of this embodiment, when a client of a CDN service user sends a data transmission request to a CDN edge node through a CDN service user, the CDN edge node transmits data acquired from the CDN service provider deployed on the client to the client in response to the data access request, and the client can audit and verify the currently received data based on a data fingerprint acquired in advance, that is, by combining a block chain network and a content distribution network, mutual constraint is achieved among the CDN service user, the CDN service provider, and the CDN edge node through a block chain in the data transmission process, so that transmission data is prevented from being tampered with by any one party, the problem of low data credibility due to the risk of tampering of data in the existing content distribution network is solved, and data credibility of multi-party operation of the content distribution network is improved.
