Congestion control
Consider the effect of using slow start on a line with 10 msec round trip time. The receiver window and the size of congestion window are set to 38 KB and 36 KB respectively. Sender side threshold is set to 18 KB. After 8 transmission a timeout occurs, after time out, the time taken to send first full window of 18 KB is ________ (in msec).

Q: Suppose an application generates chunks of 40 bytes of data every 20 msec, and each chunk gets encapsulated in a TCP segment and then an IP datagram. What percentage of each datagram will be overhead, and what percentage will be application data? Please someone who knows explain also. Thanks in adv. - Madhav.

CN_METest_TCP
I have a doubt here. Case 1: If we don't use time-stamp option in tcp, then the maximum segments that I can send in 1 TCP session is $2^{32}$ Since each segment size is 1460Bytes, maximum data that can be sent is $1460*2^{32}$ Bytes ( ... sequence number wrap around won't be a problem.Then in this case, what file size should we assume? is my analysis correct in both cases?

I have a doubt here. When timeout occurs, the congestion windows size is 18MSS.and Till now total RTT before this timeout were 6. Now, my threshold will be set to 9MSS and congestion window will start from 1 MSS.So, now when I send 1MSS window and receive it's ack and then my window size changes to 2MSS, will this RTT be counted as 7th RTT or the 8th RTT?
