EPAN EPAN is a protocol analyzer that can generate traffic statistics. Gathering data from probes, it can show utilization rates or which protocols are generating the most traffic. EPAN can also capture Ethernet frames like a traditional protocol analyzer. Ethereal is a protocol analyzer that runs on Unix. It captures data from a network connection or reads data from a file created by tcpdump.
Managers can use the software to filter out packets and look for specific transactions.
Netperf Netperf is a tool for benchmarking. It can also measure performance for TCP, UDP and other protocols. Originally developed by Hewlett-Packard, Netperf is now distributed free. Ntop Ntop shows network usage. It displays what hosts are connected to the network and which are the top talkers.
