Embodiment Construction

[0020] In this example, if figure 1 As shown, a netlib-based fast isolation switching system is adopted. A netlib-based fast isolation switching system includes internal network devices and external network devices. Wherein, the internal network device is used to collect information and transmit the information to the external network device; the internal network device has a built-in Linux kernel for the internal network and a server end based on the netlib module, and a built-in tcp / ip protocol stack I for the Linux kernel for the internal network. The netlib module in the server has a built-in tcp / ip protocol stack II; the external network device is used to receive intranet information; the external network device has a built-in Linux kernel for the external network and a client based on the netlib module; the built-in Linux kernel for the external network has a tcp / ip protocol stack i, the netlib module in the client has built-in tcp / ip protocol stack ii; the server end co...

Abstract

The invention discloses a netlib-based rapid isolation switching system, which is characterized in that an acquisition unit, a sending unit, a receiving unit and an analysis unit are in one-way communication connection in sequence, and the analysis unit is in communication connection with the sending unit. The acquisition unit is used for acquiring actual service scene data and network flow; the sending unit is used for packaging and sending the data acquired by the acquisition unit; the receiving unit is used for receiving the data packet sent by the sending unit, collecting system state dataaccording to millisecond precision and sending the collected system state data to the analysis unit, and the analysis unit is used for analyzing the received system state data and generating a time sequence database according to the system state data. By combining the system state of the data packet loss rate acquired and analyzed in the actual data transmission process and the mode of intelligently and dynamically adjusting the sending speed, it is ensured that data can be accurately received, and meanwhile existing hardware can be better utilized to achieve one-way transmission of balance performance and reliability.

Description

technical field [0001] The invention relates to the technical field of data isolation switching. Specifically, a fast isolated switching system based on netlib. Background technique [0002] The current isolated switching system is mainly implemented based on the Linux kernel protocol stack. In the process of mass data exchange and high-speed transmission, data will be frequently copied between device I / O and system memory. Bring great pressure. Contents of the invention [0003] For this reason, the technical problem to be solved by the present invention is to provide a fast isolation switching system based on netlib, which can not only provide high-speed data transmission function, but also reduce CPU overhead on the basis of ensuring data forwarding. Define filter rules. [0004] In order to solve the above technical problems, the present invention provides the following technical solutions: [0005] A fast isolated switching system based on netlib, including: [0...
