Troubleshooting of bandwidth
Monitoring and analyzing traffic and bandwidth are two vital tasks for every environment and help in identifying gridlocks.
Packet/traffic analysis and flow analysis are two mechanisms help in measuring network traffic. Packet/traffic analysis determines the contains, transactions and communication details of individual packets whereas flow analysis provides details of traffic flow within network.
The different way of measuring traffic.
Protocol analysers: These analysers examine the network conations based on packet. They perform analysis on conversation between network devices by which network administrator gets a brief idea of individual transactions between tow devices.
Hardware probes and distributed analysers: Such analysers overcome the restrains of protocol analysers by considering an individual packet.
Traffic flow analyser: Traffic flow analysers directly receive flow data from monitored devices. These tools have data flow capturing capabilities that enable users to be hassle free of hardware probing.
