In order to capture the right set of a packets stream, you would need to know where to place your protocol analyser. Depending on the requirements (source of packets, number of packets, type of packets, and more), a protocol analyzer needs to be placed at a certain point in the network. Also, a few configuration changes in a network device may be necessary, such as switch configuration changes (mirroring is done in network switches to capture packets from one or more sources). The following sub sections discuss a few means of assessing the best way of configuring protocol analyses in certain types of topology.
It is relatively easy to sniff in a hub-based network topology, because you've got the freedom to place the sniffer at any place you want, as hubs are designed to broadcast each and every packet to all connected devices.
However, due to such design deficiencies, hub-based network topologies face issues in terms of overall performance. Network...
