System and method of implementing limitation of public network access user number based on Linux for CPE (Customer Premise Equipment)

Abstract

The invention discloses a system and a method of implementing limitation of a public network access user number based on a Linux for CPE (Customer Premise Equipment), relating to the field of CPE equipment. The system comprises a DHCP (Dynamic Host Configuration Protocol) module and a public network user access number limiting module, wherein when the DHCP module checks status information of equipment at a LAN (Local Area Network) side at each time, an iptables forwarding table rule is eliminated, and the previous check information is eliminated, so that the current result is taken as a standard at each check; the public network user access number limiting module is used for eliminating recorded blacklist and whitelist and un-limiting the public network user access number if a public network user access number limiting function is closed, and obtaining an IP (Internet Protocol) address of the equipment at the LAN side, carrying out terminal identification through DHCP Option60 and distinguishing the equipment type if the public network user access number limiting function is opened. According to the system and the method, the maximum quantity for synchronous access of the public network can be limited, individual limitation of the public network access number can be carried out on each terminal type, and a function of individual limitation of the public network access number is enriched.

Description

technical field [0001] The present invention relates to the field of CPE (Customer Premise Equipment, customer premise equipment) equipment, in particular to a system and method for CPE equipment to limit the number of public network access users based on Linux. Background technique [0002] For the sake of security management and improvement of Internet access quality, CPE equipment is required to support the restriction on the number of terminals accessing the public network at the same time, which can be based on the accessing IPv4 (Internet Protocol Version 4, Internet Protocol Version 4) private network address, IPv6 (Internet Protocol Version 4) Protocol Version6, Internet Protocol Version 6) global address or MAC address (physical address) to count the number of Internet terminals, can only limit the total number of users accessing the public network, and the function is relatively simple. Contents of the invention [0003] The purpose of the present invention is to...
