Traffic Analyzers

Definition

Traffic analyzers are tools used to monitor and analyze network traffic data in order to optimize performance, ensure security, and troubleshoot issues. By capturing packets of data as they travel across the network, these tools provide insights into the types of traffic present, the sources and destinations of data, and overall bandwidth usage. They play a crucial role in understanding the network's behavior, which is essential for maintaining the integrity of various network topologies.

5 Must Know Facts For Your Next Test
