Hello All, I have a query regarding TCP upload result. I was running Flent on a testbed of four nodes connected serially. n1<---->n2<---->n3<---->n4 Flent Client: n1 netserver: n4 TCP used: BIC Test length: 30 I ran tcp_2up test and observed that one flow starts with high throughput and other with low (available in attachment). In my opinion, both should start from low throughput and grow higher (because of slow start algorithm). I want to know that, what are the reasons behind such behavior? Thanks and Regards, Sourabh Jain
