Intranet Performance Monitoring and Problem Solving Analysis with Network Parameters from SNMP and NetFlow
Panisara Treesorn, Suwat Pattaramalai · 2013
The method for solving the problem of network traffic latency with SNMP and NetFlow parameters is proposed. The analysis is taking experiment in the big communication organization in Thailand. The SNMP parameters can show an accuracy of the connection and the anomaly on router. While NetFlow parameters can show the rate of traffic flow such as: Source IP, Destination IP, Application, Port, Protocol and Traffic. By monitoring router, all mention parameters can inform the network characteristics of the router. The router is monitored with Solarwinds program to pull SNMP parameters and with NetFlow analysis program to pull NetFlow parameters of network. Then these parameters are analyzed by referring to the policy of organization network. As a result, these parameters provide enough information to administrator for managing the network. The problem can be specified correctly and solved to improve the organization network performance. Keywords—SNMP, NetFlow, Performance, Router, Protocols, Port TCP-UDP. I. INTRODUCTION ETWORK system is importance in a large organization to be accessed for internal - external data rapidly and accurately. The network administrator is required to control, diagnose, debug and improve efficiency the network devices. Nowadays, this problem in organization network is a utilize traffic latency to internal system and internet. The traffic monitoring with PRTG in the organization network can show the graph of traffic only which is not sufficient for analysis. Generally, research network monitor focus data flow on the router because it indicates behavior in communication network. Largely, the data capture methods and the analysis is the behavior monitoring on the router with data capture such as: Ethereal, WinDump, Etherpeek, Observer and Sniffer-Pro etc. (1). The network monitoring is an important activity for the network management. In network data detector, independent developing program simulates patterns of traffic,
