The question is pretty broad. On our enterprise networks we use four different products to determine latency and packet loss. On the local and wide area we utilize snmp and rmon to gather statistics, but that does not always give you a complete picture, especially if your data traverses public carriers etc. To gather end to end throughput, latency, and loss measurements we use Chariot, this was originally a Ganymeade product but is now NetIQ. On the free side Ttcp is the closest thing I know of. To monitor specific traffic flows protocol analyzers will provide you with a true picture of data loss and latency. We tend to capture the traffic of interest, and then get detailed information about the conversation in each direction with NetCalibrate / NetPredict. We have not found a single tool but rely on a few in combination depending on the problem we are trying to solve. Ping is not a solution when troubleshooting.
If you want to test results in a laboratory situation Spirent has products under Adtech or SmartBits, there is also Ixia. http://www.netiq.com/products/chr/default.asp http://www.sniffer.com/ http://www.netpredict.com/ http://www.thetechfirm.com/ http://www.spirent.com/operations/communications.html http://www.ixiacom.com/ Aloha Shawn ----- Original Message ----- From: "Michalis Palis" To: Sent: Tuesday, April 02, 2002 8:08 PM Subject: Network latency [7:40295] > Dear all > > I am looking for a goot tool to measure network > latence and packet loss.
