My UDP test is a single port send-reply system. I'm using, like I say before SIPp (http://sipp.sourceforge.net/), which goal is to generate a lot of SIP calls. But, in my case, it's not very different than your udp ping-echo (2 packets, send and reply ). I think this test can qualify for a high throughput test (I have only one network card, and I generate something like 14-15 MB of traffic on my network, with 3 old computers.). If your are interested by this kind of test, I can send you the program. >>>When there are problems with UDP, won't there be a whole lot >of ports tied up on the UDP server with packets that haven't >found anywhere to go? I not very easy with UDP. I know it's not reliable, but I don't know what kind of action a standard ethernet card or my switch take. But I have just realized a direct test between my client and my server, and I just have 50% of network utilization without problem. -- Grasland Pierrick ENSSAT - LSI 3 _______________________________________________ LinuxVirtualServer.org mailing list - [email protected] Send requests to [EMAIL PROTECTED] or go to http://lists.graemef.net/mailman/listinfo/lvs-users
