Thanks to all those who responded. I am going to be focusing on reviewing the Sun Bandwidth Manager software as well as the Linux NistNet as a solution. Suns bandwidth manager product will do this.. It works pretty good to:) http://wwws.sun.com/software/bandwidth/overview/ -Mike ------------- get yourself a copy of - NistNet (it's free and runs on Linux) http://snad.ncsl.nist.gov/itg/nistnet "it allows an inexpensive PC-based router to emulate numerous complex performance scenarios, including: tunable packet delay distributions, congestion and background loss, bandwidth limitation, and packet reordering / duplication" we use a lot and think its great. -Mark ------------- you could try changing to half duplex and also bringing down port speed on one side. throw traffic to it's interface from another host spray maybe. -Chris ------------- You could insert a cisco router inbetween them with QOS/traffic shaping turned on (or, use a Packeteer for this same purpose.) Alternately, 250mS is right around what a slow modem would give you. Consider inserting two linux boxes running PPP over a null modem cable. Turn the speed down to 19.2K or something dismal and you'll have tons of latency. -John ------------- Look into getting dummynet installed on a BSD system. -Alan > Simulating Network Latency > > What is the best way to simulate network latency between > two Solaris 8 machines (1x4500, 1x220) that are on the same > subnet, running at 100M?
