Problems solved by technology

[0004] Since the encryption and forwarding of all data are processed in the same thread, the processing efficiency is low
When there is a large amount of data to be transmitted, each data will wait for a long time before being transmitted to the SSLVPN server, the data transmission delay is high, and the transmission performance of the SSL VPN client is insufficient

Embodiment Construction

[0026] Aiming at the problems existing in the prior art, an embodiment of the present invention proposes a data transmission method, which is applied to a system including an SSL VPN client and an SSL VPN server. Wherein, in order to enable the user equipment to access the data of the internal network from the external network, an SSL VPN client may be configured on the user equipment, and an SSL VPN server may be configured on the internal network. In the embodiment of the present invention, the SSL VPN client runs in a multi-core CPU (Central Processing Unit, central processing unit) environment.

[0027] Among them, SSL VPN includes two access methods, one is the Web access method, in this Web access method, there is no need to install the SSL VPN client, and the SSL VPN server can be directly accessed through the browser. The other is the IP access mode. In this IP access mode, an SSL VPN client needs to be installed, and the SSL VPN server is accessed through the SSL VPN ...

Abstract

The invention provides a data transmission method and device. The method comprises the steps of establishing multiple VPN channels corresponding to the number of CPU cores between an SSL VPN client and an SSL VPN server, and allocating a VPN channel to each CPU core; for data to be sent to the SSL VPN server, determining the CPU cores corresponding to the data by the SSL VPN client through utilization of information of the data and the number of the CPU cores; and providing the data for the CPU cores by the SSL VPN client, and sending the data to the SSL VPN server by the CPU cores through the VPN channels allocated to the CPU cores. Through adoption of the technical scheme of the method and the device, all data is encrypted and forwarded in multiple threads; the problem that the performance of the SSL VPN client is insufficient when mass data is transmitted at the same time is solved through the multiple threads; the processing performance of the SSL VPN client when the mass data is transmitted is effectively improved; the data transmission delay is reduced; and the processing efficiency is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission method and device. Background technique [0002] With the continuous development of network technology and the popularity of the Internet, more and more government and enterprise organizations have begun to use the Internet to handle work matters. In order to ensure the security of internal data, VPN (Virtual Private Network, virtual private network) technology has become the implementation method for user equipment to access internal data from the external network. VPN technology establishes a private network on the public network to achieve remote access. SSL (Security Socket Layer, Secure Socket Layer) is a secure data transmission standard used on the Internet. By using encryption technology to transmit data on the Internet, it is guaranteed that the data will not be eavesdropped or modified. Therefore, the SSL VPN access method can be used...
