Re: latency in a lab scenario [7:6453]
Daniel, There are different modular interfaces you can purchase for the RDS. i.e.. we have RS-449 and RS-232. The RDS sits between two routed interfaces and acts as the DCE. The cables you need are DTE for the router and the interface style you purchase for the RDS (should be the standard cables you use now). The bandwidth and latency are changed through dip switches on the front panel of the RDS. The only downside we found was the bandwidth speed that tops out at 2.048 Mbps. Adtech has a more advanced product that can scale up but the price difference is hefty. We have been very happy with the product and it allows us to test applications to specific what if scenarios. The tech support at East Coast Datacom's was also very responsive any time we called in with questions. Hope this helps Aloha Shawn - Original Message - From: Daniel Cotts To: 'Shawn Goodson' ; Sent: Thursday, May 31, 2001 6:54 AM Subject: RE: latency in a lab scenario [7:6453] Did this connection reqire any special cables or configuration?

Re: latency in a lab scenario [7:6453]
If your routers are connected serially, lower the clockrate on the DCE interface to the desired speed. If you want to introduce variable latency, I'd have to think about it for a bit. A simple way would be to do FTP transfers or large extended pings from time to time to simulate traffic. There's probably a more automatic way to do it but my brain hasn't quite engaged today.

RE: latency in a lab scenario [7:6453]
Several companies make boxes that create latency in a serial link. The really neat ones can also induce jitter, packet drops, and other likely line faults. An affordable one is: http://www.ecdata.com/rds/rds.htm FWIW The manufacturer sells at list price. Some time after inquiring with them an outside Rep called me and quoted about 70% of list. Sorry, I don't have his name handy. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Wednesday, May 30, 2001 10:31 AM To: [EMAIL PROTECTED] Subject: latency in a lab scenario [7:6453] Hi, I'm looking for ideas to induce latency in a lab scenario.
