Abstract
In network management and monitoring systems, or Network Management Stations (NMS), the Simple Network monitoring Protocol (SNMP) is normally used, with which it is possible to obtain information on the behavior, the values of the variables, and the status of the network architecture. network. However, for large corporate networks, the protocol can present latency in data collection and processing, thus making real-time monitoring difficult. This article proposes a multi-agent system based on layers, with three types of agents. This includes the collector agent, which uses a Management Information Base (MIB) value to collect information from the network equipment, an input table of information from the network devices for the consolidator agent to process the collected data and leave it in a consumable format, and its subsequent representation by the application agent as a web service, in this case, as a heat map.
Highlights
Today’s networks are dynamic, and numerous transactions per second between different clients, applications, sensors, and devices are needed to deploy new services, which consumes the information generated throughout the network ecosystem
The information is analyzed by the consolidator agent, and it creates information files to present on the application layer as a heat map and information table on the web server. The results of this empirical approach presented below are not comparable with other schemes proposed in the literature, such as those presented by Isaza et al (2007), which are based on simulation environments
The multi-agent system prototype used for network monitoring was implemented and deployed in computer equipment and network devices such as switches or a router
Summary
Today’s networks are dynamic, and numerous transactions per second between different clients, applications, sensors, and devices are needed to deploy new services, which consumes the information generated throughout the network ecosystem. Traditional communication between network devices (Core and End Users) generates transactions in traffic control. The Simple Network Monitoring Protocol (SNMP) is used to analyze traffic, with the purpose of allowing the administrators to change and monitor the state of devices that support the protocol, for instance, by shutting down an interface, checking the users on a Vlan, counting the users’ sessions, etc. The SNMP has two types of entities: managers and agents. Managers work in Network Management Stations (NMS) and receive messages and traps from SNMP agents. SNMP agents, in turn, provide management information to the NMS. The SNMP protocol uses a hierarchical structure called Management Information Base (MIB). This structure is a database of managed objects containing information about the devices and the network.
