During/after the testrun I want to know if the connections got a fair share of the bandwidth. Can anyone recomment tools for this? After the test I would also like to, "deep-dive" analyse one of the TCP streams to see how the congestion window, outstanding-win/data is behaving. Back in 2005 I used-to-use a tool called "tcptrace" (http://www.tcptrace.org). Have any better tools surfaced? -- Best regards, Jesper Dangaard Brouer MSc.CS, Sr. Network Kernel Developer at Red Hat Author of http://www.iptv-analyzer.org LinkedIn: http://www.linkedin.com/in/brouer
