What protocol should Jonquil consider for monitoring traffic flowing through network routers and switches?

NetFlow is a network protocol developed by Cisco for the collection and monitoring of network traffic data as it flows through routers and switches. It enables the analysis of traffic patterns, bandwidth utilization, and overall performance of the network. By using NetFlow, network administrators can gather valuable metrics related to packet flows, including source and destination IP addresses, interface types, and more. This capability is particularly essential for identifying and responding to network issues, ensuring optimal performance, and improving security by detecting unusual traffic patterns.

Other protocols mentioned, such as HTTP, FTP, and SMTP, serve different purposes. HTTP is used primarily for transferring web content, FTP for file transfers, and SMTP for email transmission. These protocols do not provide the specific traffic monitoring capabilities that NetFlow offers, making NetFlow the appropriate choice for this context.
