Consider a site that chooses to subnet a class B network address,
but decides that some physical nets will use 6 bits of the local
portion to identify the physical net while others will use 8.
Find an assignment of host addresses that makes destination addresses
ambiguous
Assume TCP is sending segments using a maximum window size of
64Kbytes on a channel that has infinite bandwidth and an average
roundtrip time of 20 milliseconds. What is the maximum throughput?
How does throughput change if the roundtrip time increases to 40 milliseconds
請高手幫我解答,感激不盡
