Network system based on optical fibers and coaxial cables and control method thereof

Abstract

The invention discloses a network system based on an optical fiber and a coaxial cable, and the system comprises: ONU equipment which is connected with the optical fiber; an EOC local side which is connected with the ONU equipment; a set top box which is connected with the EOC local side, wherein the set top box can be in wireless communication with the terminal; and auditing AC equipment which is connected with the ONU equipment so as to carry out security auditing on the terminal. The auditing AC equipment is connected with the ONU equipment, a data packet sent by the terminal is transmitted to the ONU equipment through the set top box and the EOC local side; the ONU equipment forwards the data packet to the auditing AC equipment; the auditing AC device generates auditing data accordingto the data packet, the auditing data and the data packet are uploaded to the Internet through the ONU equipment; in this way, safety audit of the terminal is achieved; when related regulations are met, under the condition that the overall network architecture is not changed, it is not needed to add an AP device with an audit function to each user, safety audit can be achieved only by adding oneaudit AC device additionally, the cost for purchasing the device is greatly saved, and daily maintenance is facilitated.

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.
