The application relates to the technical field of Fintech (Fintech), and discloses a verification code request processing method, which comprises the following steps: sending a verification code request to a verification code system and receiving initial parameters fed back by the verification code system based on the verification code request; drawing a to-be-verified picture according to a preset drawing algorithm and the initial parameters and outputting the to-be-verified picture; receiving verification information corresponding to the to-be-verified picture and determining whether the verification information meets preset verification requirements; and if yes, sending a verification duration in the verification information to the verification code system, wherein the verification code system checks the verification duration. The application also discloses a verification code request processing device, equipment and a computer storage medium. The application reduces traffic cost and improves the efficiency of a mobile terminal verification code verification process.

The invention relates to the technical field of computer networks, and discloses a multistage CDN (Content Delivery Network) traffic scheduling method based on linear constraint, which comprises the following steps of: receiving an access request analyzed by a local DNS (Domain Name System) to form a scheduling instance to be optimized; carrying out complexity discrimination on the scheduling instance, and determining an applicable scheduling category of the scheduling instance; establishing a performance upper limit model related to server hardware resources; functional linear constraints are introduced, and Big-M parameters related to the constraints are finely set; and server cluster information, server information, quality constraint information and region hijacking information are obtained, joint solving is performed on the performance upper limit model and the functional constraint, a target cache node IP address meeting all constraint conditions is determined and fed back to a local DNS, and response and scheduling of an access request are completed. According to the invention, through a multi-stage scheduling framework and refined Big-M parameter setting, the computational efficiency and resource utilization precision of CDN scheduling in a complex network environment are improved.

This invention provides a data transmission method and system for smart devices based on a 5G communication module. The data transmission method includes: real-time hierarchical processing of data packets to be transmitted according to a preset hierarchical strategy; real-time monitoring and acquisition of communication link status parameters, and prediction of the service quality change trend of each communication link within a short future time window based on historical status data using a time series prediction model; dynamic decision-making on the transmission path and transmission mode of single or batch data packets based on the priority of the data packets and the current and predicted communication link status, using a preset communication optimization strategy; encrypting the data packets using a data security strategy selected according to the priority and security requirement level of the data packets; and sending the encrypted data packets to a network edge node or cloud as the receiving end. This invention effectively ensures the low latency and high reliability transmission requirements of high-priority data, reducing overall energy consumption and traffic costs under 5G networks.
