: : 1. To make the initial sequence number a random number,
: : most systems start the counter at 1 during bootstrap and increment the
: : counter by 64,000 every half second.
: : How long does it take for the counter to wrap around？
: sequence number is 32-bit long, so the duration would be:
: (2^32 / 64,000) * 0.5 ~= 33,554 sec
: : 2. In a connection, the value of cwnd is 3000 and the value of rwnd is 5000.
: : The host has sent 2000 bytes which have not been acknowledged.
: : How many more bytes can be sent？
: the total data allowed to be sent is min(cwnd, rwnd), so
: min(3000, 5000) - 2000 = 1000 bytes
: more data can be sent.
: : 拜託，謝謝^^
真是謝謝你詳細的解答^^
感謝，再感謝^^
