Network Analysis helps companies and professionals on the Internet for their capture and monitor network traffic to determine more precisely what happened in the network. With continued growth in corporate intranets, it is of crucial importance for system administrators and security professionals to know different types of traffic crossing their networks. To ensure uninterrupted network services, it is important to make the network traffic monitoring and analysis. This facilitates troubleshooting and effective resolution of immediate problems that may occur.

monitoring of network traffic: what it is and why

monitoring network traffic is the method that lets you spy on the exchange of data packets on the network can. It is necessary to perform in the following situations:

/ p> Audit debugging configurations

analyze usage patterns

Traffic patterns are controlled over a network using network monitoring tools, hardware and software. They act as a network traffic sniffer. The tracking tool sniffs hook in the movement, if any, and sends alerts to the network administrator via e-mail or pager.

Any break in a computer network could collapse in the exchange of information between employees of an organization and lead with the customers. The companies can get down to assess the statistics of the monitoring network. The result can be a huge loss of revenue, productivity and resources. A number of elements in a network, including switches, routers, WAN, or mail servers require regular monitoring. to inform a monitoring tool diagnoses the problem and at the earliest. This allows network administrators and security professionals to remain equipped for the future network outages in the analysis of network problems.

Tools Network Traffic Monitoring: Considerations

Look at the size of your network before a decision tool for monitoring network traffic. If your network goes from small to medium sized, download freeware. The purchase of a network monitoring tool that supports the monitoring of servers, systems, networks and applications. A monitoring tool to acquire data-bandwidth network supports the use of protocols such as SNMP and NetFlow and packet sniffer applications.

Packet Sniffer: He sniffs all network data packets passing the network card of a computer network. He classifies the network traffic according to various parameters, including the IP address and the protocol.

NetFlow: The protocol measures the bandwidth and classify network traffic based on parameters such as IP address and protocol. It is ideal for high-traffic networks. However, it only works with Cisco routers.

SNMP: Simple Network Management Protocol monitors how much bandwidth of routers and switches used. It can also read the memory and CPU usage.
