Obviously, in the above process, the service support system performs centralized management on the user traffic, and as the mobile services increase, the centralized structure inevitably increases the design difficulty and increases the design cost; therefore, to solve the above problems, embodiments of the present invention provide a decentralized flow control method and network device; so that the manner in which the features and aspects of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings.
Example one
The present embodiment provides a flow control method, and in particular, provides a method for distributed flow management based on a blockchain technique, which can achieve the purpose of decentralized point-to-point flow use or transaction, and meanwhile, also solve the problems of user security and privacy.
Here, the blockchain can be viewed as a public ledger that keeps track of all traffic transactions, which each participant in the network sees as an authoritative record of ownership. The conventional traffic management method relies on a centralized service support system to provide settlement service to verify and process all traffic transactions, however, the blockchain described in the present application is not created by the service support system, but is independently created by nodes in the network (i.e., the network devices described in the present embodiment), and the traffic transactions added to the blockchain are all regarded as transactions processed by the network devices, so that the present embodiment can use the blockchain to determine whether the traffic transactions are completed. Specifically, fig. 3 is a schematic flow chart illustrating an implementation of a flow control method according to an embodiment of the present invention; the method is applied to network equipment; as shown in fig. 3, the method includes:
step 301: the method comprises the steps that network equipment obtains flow request information aiming at a target client; the traffic request information at least carries address information of the target client;
in this embodiment, for different types of traffic request information, the traffic request information may also carry a specific number of traffic required, for example, for traffic enrichment information, the traffic request information may also carry a number of traffic required to be supplemented; when the traffic usage information is used, the traffic request information may also carry the traffic amount of the target application that needs to be downloaded, and the like. In practical application, the specific information carried in the traffic request information may be determined according to actual requirements.
Here, it is to be noted that the method described in this embodiment may be implemented by one network device, or may be implemented by different network devices.
Step 302: creating a target traffic transaction for the address information based on the traffic request information and adding at least the target traffic transaction to a new block;
in this embodiment, before adding the target traffic transaction to the new block, the validity of the target traffic transaction also needs to be verified, and then after determining that the validity of the target traffic transaction passes verification, at least the target traffic transaction is added to the new block. Here, the target traffic transaction added to the new block is a traffic transaction processed by one network device, so that it is convenient for other network devices to determine the completion degree of the target traffic transaction by using the new block. In practical applications, verifying the validity of the target traffic transaction may specifically include: the syntax and data structure of the target traffic transaction, the validity of the target traffic transaction, the signature of the target traffic transaction, etc. are verified.
In this embodiment, the network device stores information of the block chain, so that it is convenient to determine the completion degree of the target traffic transaction based on the block chain; specifically, the network device stores the first blockchain; further, after adding the target traffic transaction to a new block, the network device also adds the new block to the first block chain, and broadcasts the first block chain added with the new block to a network corresponding to the network device, so that other network devices can obtain updated block chain information in the network; similarly, the network device also obtains a new block chain from the network corresponding to the network device, for example, obtains the first block chain added with the new block, and replaces the stored old first block chain with the first block chain added with the new block, so as to complete updating of the block chain. That is, the blockchain stored in the network device is updated based on the blockchain information in the network, so that the network device can use the blockchain to determine whether the traffic transaction is completed.
Step 303: acquiring a first block chain, and judging whether a new block aiming at the target traffic transaction exists in the acquired first block chain so as to determine whether the target traffic transaction is completed;
in this embodiment, when the determination result indicates that a new block for the target traffic transaction exists in the first block chain, the target traffic transaction is completed, and at this time, the network device generates traffic request confirmation information and sends the traffic request confirmation information to complete a traffic management process for the target client to which the address information is directed; otherwise, the network device considers that the target traffic transaction is not completed, and continues to acquire a new block chain from the network corresponding to the network device, and further continues to execute the determination process of step 303 until it is determined that the target traffic transaction is completed, and then sends a traffic request confirmation message.
Step 304: and determining whether to generate and send traffic request confirmation information based on the judgment result so that the network equipment completes a traffic management process of the target client to which the address information aims.
In a specific embodiment, the traffic request information may specifically be traffic recharging information, and the traffic recharging information at least carries address information of the target client and a first number to be recharged; at this time, the network device supplements the address information with the first amount of traffic, creates a target traffic transaction based on the address information and the first amount, and further adds at least the target traffic transaction after the self-processing is completed to a new block.
In another specific embodiment, the traffic request information may also be traffic usage information, and the traffic usage information carries at least address information of the target client; at this time, the network device determines a required second quantity based on the traffic usage information, for example, when the traffic usage information is specifically traffic download, the second quantity is a specific traffic of the target application that needs to be downloaded; when the traffic usage information is specifically a browsing webpage, the second quantity is a preset specific traffic value for the browsing webpage; the network equipment creates target flow transaction according to the address information and the second quantity; here, in practical applications, before providing a traffic service for a target client based on a target traffic transaction, the network device may further obtain user information of the target client, authenticate the user information, and provide the traffic service for the target client based on the target traffic transaction after the user information passes the authentication.
Further, in practical application, the second amount allocated by the network device to the target client is not the actual traffic used by the target client, so that, in order to facilitate traffic deduction by the network device according to the actual traffic usage state, the network device may also monitor a traffic service process; specifically, when detecting that the traffic service for the target client is ended, the network device obtains the actual traffic usage amount of the target client, and creates a new target traffic transaction for the address information based on the actual traffic usage amount, so that the remaining traffic amount for the address information is represented in the new target traffic transaction; wherein the remaining number of flows is determined based on the second number and the actual number of flows used; and the network device verifies the validity of the new target traffic transaction, and after it is determined that the validity of the new target traffic transaction passes, at least the new target traffic transaction is added to a new block (in practical applications, the new block may be the same as the new block in step 302, or another new block, that is, multiple pieces of traffic transaction information may be stored in the block), so that the network device manages the traffic usage process of the target client to which the address information is directed.
According to the method, flow request information for a target client side is obtained through network equipment, a target flow transaction for address information is created based on the flow request information, the target flow transaction is at least added to a new block, the new block is compared with a block in an obtained first block chain, whether the target flow transaction is completed or not is determined, and a flow management process for the target client side for the address information is completed; in the embodiment of the invention, because the network equipment is utilized to assist the conventional service support system to manage the user flow, the conventional centralized management mode is broken through, and the aim of decentralized management is fulfilled; in addition, in practical application, the network device described in this embodiment can perform the function of the network device for different nodes in the existing network, so that the purpose of decentralization is further achieved, and a foundation is laid for solving the problems of user security and privacy.
