Hi, We are facing problem in realizing two way interaction with Access grid. We have a dedicated network across three different cities with multicast enabled in our routers. I believe each venue can be configured with only one multicast group ip address with separate ports for video and audio transmission.
The network provider is saying that a node cannot be source as well as receiver at the same time but in AG it is observed that all the hosts participating in a particular venue session are transmitting both audio and video. He is saying it is not the right way of experimenting bidirectional communication thru audio/video. He is asking whether AG supports Source Specific Multicast or not, because he is saying bidirectional communication thru audio/video can be realized only thru SSM support. But i did not find any means on how to configure SSM in access grid. I am using AG 3.1 all in one windows installer. Some times we are facing audio echo and some times noise problem. I am not able to understand whether it is because of audio devices or network configuration. Can you throw some light on where the problem could be as we are not able to conclude whether it is due to network or audio devices. Regards, Satya -- N.
