Network system based on optical fiber and coaxial cable and its control method

Abstract

The invention discloses a network system based on optical fiber and coaxial cable, comprising: ONU equipment, connected with optical fiber; EOC central office, connected with ONU equipment; set-top box, connected with EOC central office, and the set-top box can communicate wirelessly with the terminal; Audit AC equipment , to connect with the ONU device to perform security audit on the terminal. The audit AC device is connected to the ONU device, and the data packet sent by the terminal is transmitted to the ONU device through the set-top box and the EOC central office, and is forwarded by the ONU device to the audit AC device. The audit AC device generates audit data according to the data packet, and then sends the audit data and The data packets are uploaded to the Internet through the ONU device, in this way, the security audit of the terminal is realized, and the relevant regulations are met. Under the condition that the overall network structure remains unchanged, there is no need to add an AP device with audit function for each user, only a new Security audit can be realized by adding an audit AC device, which greatly saves the cost of purchasing equipment and facilitates daily maintenance.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a network system based on optical fiber and coaxial cable and a control method thereof. Background technique [0002] Due to development reasons, the general communication structure of radio and television networks is optical fiber and coaxial cable, that is, PON (passive optical Coaxial cable transmission Ethernet data access technology) uses coaxial cable to lay the line to the user. The communication system built in the above way mainly includes the ONU (Optical Network Unit) equipment connected to the optical fiber, the EOC central office connected to the ONU equipment, and the set-top box connected to the EOC central office through a coaxial cable. The set-top box generally has a WIFI function. [0003] For the sake of network security, Internet service providers and network users should implement Internet security protection technical measures to record and save user l...

Problems solved by technology

[0004] In the prior art, the set-top box has a WIFI function, and the set-top box dials up to connect to the Internet, but it cannot perform security audits on each wireless terminal (mobile phone or computer, etc.). In order to meet the requirements, the general solution is to add an audit function on the user side The AP (wireless access point) device is connected to the set-top box. However, adding a new AP device with audit function for each user is not only costly, but also a large number of devices means that there are more possible fault points, which is inconvenient for maintenance and repair.
