You need a pc at each end of the link. Use the udp test as it measures loss and jitter and let's you set the rate/throughput of the test stream. Ntop is good for viewing who is doing what, not generating traffic for validation tests. ------Original Message------ From: Darren Best To: [email protected] ReplyTo: [email protected] Subject: [Ntop] Testing and Monitoring the uptime and speed of a wireless network connection Sent: Oct 24, 2010 8:52 PM Hi, noob to ntop (and most things pertaining to network analysis), so please be gentle... I'm interested in exploring the possibility of establishing a wireless network connection between two buildings (this is not for me, but for a friend's business). I want to be able to evaluate the effectiveness of a network link between a wireless router at the main building and a wireless extender located at the second building (both off-the-shelf D-Link boxes). I want to be able to log the connection speed over this link over an extended period of time, so that I can see if weather conditions adversely affect the link. I want to do this for at least two weeks before I can advise him if the link is sufficiently fast and reliable (I need to see if a VOIP softphone is feasible in the remote location, so having a rock-solid link is a necessity). My question is twofold: 1) What program/tool would you use to generate a constant stream of consistent traffic over the wireless link (in order to measure the speed and/or reliability of the connection)? Would this require a dedicated computer, or could a lightly-used "production" PC do the job without causing it performance issues? Would I also require another computer attached to the extender at the other end, or can traffic be "received" by the wireless extender alone? 2) (Assuming I can do step 1), is ntop the correct tool for analyzing and logging this data? If so, can you point me to any documentation on doing so? If not, any recommendations? Looking forward to your responses. Thanks.
