NETWORK MONITORING SYSTEM
Literature Survey
u A. Basic terminology
Network monitoring tool
Network monitoring tool is the networking tool that is used to examine usage of local area network and provide a statistical data of uploads and downloads in a network. Monitoring tool is usually used to monitor I/P traffic between the LAN and the internet. It is a network diagnostic system that is used to monitor local area network and provide a statistical display of the same. The data can be further used to improve the network efficiency. Other problems such as locating the down server, receiving incorrect work request etc can also be removed.
Ø Simple network management protocol
Simple network management protocol (SNMP) is based on agent/manager model. The model consists of an agent, a manager, a database containing information about the management and the network protocols. In SNMP the administrative computer which is more commonly called as manager has the task of monitoring and managing a group of systems in a network. The systems that are managed by the manager have a continuous program running known as agent, which reports the information to the manager via SNMP. Devices such as Routers, printers, servers etc use SNMP.
WinPcap
u It is a freeware which is used for direct network access under windows.
WinPcap provides architecture for network analyses and packet capturing for win32 platform.
WinPcap can facilitate:
u Raw packet capturing
u Filtering the packets according to the set of rules defined by the user.
u To gather statistical data related to network traffic.
B. Why do we need it??
u Network Traffic Monitoring (NTM) is a network analytic tool that observes local area network usage and provides a statistical display of uploads and downloads in a network. The network display monitor displays following information:
u • Source address of the system that sends frame to the network.
u • The protocol that was used to send the frame.
u • Destination address of the system where the frame will be received.
u • Data of the message that is sent.
u Capturing is the process by which a network monitor collects the information.
All the information is stored by default in capture buffer. Also, one can applyNETWORK MONITORING SYSTEM
