When i use NS2 to simulate some TCP trasfer
I found that i always got some gap between the first SYN packet & the second data packet.
And the ridiculous thing is, if i increase the bandwidth or decrease the link delay, the gap will get larger( can up to 10+ seconds ).
Does any1 got real experience about the TCP transfer? Is this something like TCP's feature or just the unstable case at the beginning?
If it is TCP's feature, in real cases, if i reset the TCP connection by doing close/open, will the gap appears in the following trasmission? ( i got diff results under diff protocols. They implemented the reset method differently )
Thanks a lot ^^;;
