From: "Bob Dixon" To: "The Megaconference" ; ; "Video Development Initiative" Subject: Please Join the Commons/Megaconference Load Tests Date: Tuesday, July 17, 2001 4:03 PM In preparation for the Internet2 Commons upcoming video conferencing service, a large bank of H.323 MCUs have been assembled at Ohio State University. There are over 200 ports at 384K now available. These same MCUs will be used in the upcoming Megaconference III also. (No further info is available yet on either of the above.) We really need to put a big load on this MCU bank and find out how it will fail (note that I say "how" not "if" ;) ). We have instrumented the bank and its network connections fully, so we can make detailed studies of where things go wrong, and fix them before the above events happen. So we need your help in breaking the network and/or MCUs by overloading them to the maximum level possible. This load test will occur on Wednesday July 25 from 11am to 3PM EDT. Please connect all your H.323 stations and just let them run. You do not need to stay there and talk on them, but you certainly may do so if you wish. This will be one big conference, so everyone will hear everyone. I am listing several MCU addresses below. Start calling them in the sequence shown. If you get in, stay there. If you get a busy signal, go on to the next one etc. 1. Connect by dialing with out of zone VideNet dialing: 05237350690978*1234 Or register directly with OSU gatekeeper 128.146.199.52 and then dial 78*1234. 2. Same as the above, except substitute 78*2468 at the end. 3. Same as above, except substitute 73*1234 at the end. Please send me email in advance if you plan to participate, and with how many stations, so we have some idea what to expect. Please use hardware-based clients only; no NetMeeting etc. The speed is 384K. Afterwards, you are also welcome to send me email comments on how things looked from your end. There will be more tests like this later, after we recover from this one. Thanks for your help! Bob Robert S.
