Abstract

The invention provides a VPN gateway system based on a DTLS protocol and an implementation method. The VPN gateway system comprises a function module, a CPU module and a resource configuration module.The functional module comprises a system control unit, a communication unit, a network service unit and an encryption unit; the CPU module comprises m CPU core numbers, the system control unit and the communication unit jointly occupy n CPU core numbers according to a preset mode, and m-n CPU core numbers are reserved; and the resource configuration module respectively configures the reserved m-nCPU core numbers to the network service unit and the encryption unit according to the proportional relation between the throughput rate of the network I / O and the throughput rate of the encryption algorithm. According to the method, the problems of low CPU resource utilization rate and low VPN performance caused by factors such as network I / O read-write speed, CPU processing performance and encryption algorithm complexity in traditional VPN implementation can be effectively solved; and memory copying in VPN implementation can be reduced to the maximum extent, and IP fragmentation is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a DTLS protocol-based VPN gateway system and an implementation method. Background technique [0002] Virtual private network (Virtual Private Network, VPN) refers to the use of open public network resources to establish a private transmission path to connect remote branches, business partners, mobile office workers, etc., and provide a secure end-to-end data communication technology. [0003] For example, if a company employee is on a business trip to other places and wants to access the server resources of the enterprise intranet, the VPN technology can enable the non-local employees to access the intranet resources. Its realization method is: set up a VPN server in the intranet, the VPN server has two network cards, one is connected to the intranet, and the other is connected to the public network. After connecting to the Internet locally, non-local employees fi...
