Network Traffic WLAN Monitoring based SNMP using MRTG with Erlang Theory

Abstract

Best internet network connection because of the smooth flow of data and affects performance. A network admin must supervise the internet network both in software and in terms of hardware. The main thing that a network admin does in the Central Room is to be able to realize a software such as the Multi Router Traffic Grapher (MRTG) which can function to monitor the internet network in the environment. Internet speed is determined by the amount of bandwidth available with many users accessing the network. This work was conducted using the SNMP-based MRTG application, which is used to monitor and analyze bandwidth usage. The results of the bandwidth usage will be calculated using the Erlang-B theory from the results of calculations carried out using the Erlang-B theory algorithm, a Grade of Service (GoS) value for the busiest hour is 0.095%, rounded to 0.001. This means that the probability value of all channels being active at that hour is 0.001%. This GoS value is good enough because failed access is unlikely.
