A method and device for controlling user access of a firewall in a local area network

Abstract

The invention discloses a method and a device for controlling number of users accessing a firewall of a local area network. The method includes monitoring running state of a server in real time to know using rate a of the server in real time; comparing the using rate a of the server with a preset threshold value b to judge whether the using rate a reaches the preset threshold value b or not; if yes, counting the number c1 of the users currently accessing the firewall, and adjusting an upper limit value of the number of the users allowing to access the firewall to be c1 / b. By the method and the device, the running state of the server can be monitored in real time, and when operation load of the server reaches an upper limit, the upper limit of the number of the users allowing to access the firewall can be dynamically adjusted to stop new users from accessing, so that the objective of linkage control on the firewall and the running state of the server is achieved, user queuing number of the server is reduced, calculation congestion is effectively avoided, and data transmission speed of the whole local area network is increased.

Description

technical field [0001] The invention belongs to the technical field of computer networks, and in particular relates to a control method and device for user number access of a local area network firewall. Background technique [0002] The local area network is composed of multiple network devices, usually including switches, network management, servers, PC equipment, printers, and the server is composed of small network control cameras, access switch control and security systems. According to the composition, LAN can be divided into two categories, one is network transmission, including switches and network management, and the other is users, including servers and other equipment; among them, network management mainly plays a role in controlling network transmission equipment, As the most commonly used network management device, the firewall mainly controls user access restrictions and user access restrictions. Among user devices, the server is the core device and is mainly r...

Problems solved by technology

[0005] The purpose of the present invention is to provide a method and device for controlling access of the number of users of a firewall in a local area network, which can dynamically adjust the number of users allowed to access the firewall when the computing load of the server reaches the upper limit through the linkage between the firewall and the server usage status. The upper limit prevents the access of new users, reduces the number of users in the server queue, avoids calculation congestion, and overcomes the unified upper limit control of the number of user access by the firewall in the prior art, which is inconsistent with the full load state of the server and cannot be maximized Exploitation of server performance flaws
