Design And Implementation Of Wireless Network Convergence Monitoring Platform

With the continuous deepening and development of Internet applications and the continuous expansion of wireless networks,we need to effectively manage wireless networks.Since the WIFI network is composed of thousands of APs(Wireless Access Points)of different brands,in order to continuously understand the operating status of the network platform,it is necessary to build a monitoring system for multi-brand integration in order to be effective Network failures are discovered locally,and the administrator is notified to deal with the failures in time.Although wireless device manufacturers will also provide a management platform that supports their own brand's network products,there is still a lack of a wireless network that can uniformly monitor all WIFI devices in the management of WIFI park network management composed of multi-brand WIFI devices.Management platform.There are several reasons for this:1)The incompatibility between AC(Wireless Access Point Controller)and AP of different brands has caused the heterogeneity of the wireless network management platform provided by the manufacturer.Although the communication control between AC and AP mainly adopts the CAPWAP(Control And Provisioning of Wireless Access Points Protocol)specification,because manufacturers use this protocol in different parameter definition methods,each manufacturer's AC can only control and manage itself Brand AP,so that the wireless management platform of one manufacturer cannot directly manage the wireless network equipment of other manufacturers.2)The platform in this article uses SNMP(Simple Network Management Protocol)to supervise WIFI devices.Since SNMP is widely used to manage and monitor network devices,the platform uses SNMP to collect operating data of WIFI devices for integrated supervision.At the same time,for the AP device tracking AP device based on MAC address(Media Access Control)scheme that can track the WIFI device when the IP address changes after the AP device goes offline and re-online,a WIFI device drift tracking method is proposed.Based on the above problems,this article uses the Nagios open source project framework to monitor the wireless network environment composed of multi-brand wireless network equipment,and conducts the following research:(1)Aiming at the problem that the diversification of WIFI network brands causes managers to switch between different management platforms for equipment inspections,a wireless network integration monitoring platform that can support different brands of WIFI devices has been developed.Based on the architecture of the open source project Nagios,the platform can detect abnormal phenomena such as AP drop,drift,and overload at any time,and display it on the page in a visual way.(2)The platform in this article uses SNMP(Simple Network Management Protocol)to supervise WIFI devices.Since SNMP is widely used to manage and monitor network devices,the platform uses SNMP to collect operating data of WIFI devices for integrated supervision.And proposed a WIFI device drift tracking algorithm,which is mainly aimed at tracking the WIFI device based on the MAC address(Media Access Control)of the AP device when the IP address changes after the AP device is offline and re-online.The purpose of this article is to integrate different brands and different types of wireless AC/AP devices into one management platform,thereby reducing the complexity of network administrators' inspections,and enabling personalized networks for different devices according to user needs Monitoring management.
