Sorry for being late in response Christoph, Well About the tools that I used to measure the rates , they were the vic itself and system monitor which comes by default with Ubuntu
and here is a screenshot belongs to the Receiving machine : http://muhammad.akl.googlepages.com/acc.png I tried to perform the steps you suggested but i got some errors , So I will try again and will inform you about the results . Thanks alot for your assistance.

But The New problem here which happend today (I was doing all these tests mentioned in the previous mail yesterday) when the second machine starts to receive video , the whole operating System (ubuntu) hangs ! I thought the problem was a hardware issue , so I changed the producer machine to be a Consumer and made the Consumer to be a producer , but got the same result , the Consumer machine hanged also after it received the Video , this problem didn't appear yesterday . So What do you think about this problem ? hardware issues ? Also noticed something strange : the producer machine sends the DV streams at 29 Mbps while the Consumer machine receives the DV streams at more than 100 Mbps !! Muhammed, I haven't been able to replicate this problem. The sending rate is about right but the receiving rate should be the same, not more than 3 times greater. How are you measuring the date rate - from vic itself or some other tool? Can you try running a stream point to point separate from AG? i.e. shutdown VenueClient on both machines, then cd to ~/.AccessGrid3/local_services/SimpleHDVideoService and on the sending machine run: ./runDVslow address/port where address/port means the IP address of the receiving machine and port is some highish number e.g. 45678 On the receiving machine, cd to same directory (or SimpleHDVConsumerService) and run: ./vic address/port where address is the IP address of the sending machine and port is the same number you chose when running the sending stream. How are your send & receive data rates? If the data rates seem sane, then the next step is to try the same test but replacing the IP addresses of the test machines with some arbitrary multicast address e.g. on the sending machine: ./runDVslow 233.45.67.89/45678<http://233.45.67.89/45678> and on the receiving machine: ./vic 233.45.67.89/45678<http://233.45.67.89/45678> How are the data rates on both machines now? chris Christoph Willing +617 3365 8350 QCIF Access Grid Manager University of Queensland
