Part 1
When using a sliding window of size N, how many packets can be
sent without requiring single ACK to be received?
Part 2
Suppose two program use TCP to establish a connection,
communicate , terminate the connection, and then open a new
connection. Further suppose a FIN message sent to shut down the
first connection is duplicated and delayed until the second
connection has been established. If a copy of the old FIN is
delivered, will TCP terminate the New connection? Why or why
not?
