Hi all, I am involved in a scalable Video Conferencing project and am using a machine running Red had Linux as a router. I basically want to know two things:-->>> (1)I need to configure the router so that it recognizes the TOS and Precedence bits and routes packets accordingly. (2) The videoconferencing system is setup in a Ethernet . For benchmarking the application ,I need to increase the congestion at the router delibrately and then show how my application can adapt to it. So , I need to know how to increase the congestion and also measure the same at the Winnt machine which runs the video conferencing application. So I need to calculate the congestion at the router by a program on the winnt machine,but don''t want to run any program on the Linux router.So please can anybody tell me how to access the congestion value at the Linux router ??.It would be a lot better if I could get some kind of congestion coefficient at the router . Thanking you all in advance. Rajiv Sankaran
