according to the data queried on the Internet, any element in the TCP quad belongs to a different connection. then the assumption that the same client connects to the unreachable ports of different servers is true. Open port 8081 on the server, and try...

how does RT, understand that the TCP IP protocol is data flow oriented and the UDP protocol is Datagram oriented? ...
if a socket between the client and the server is closed (the tcp connection is closed), the client will not be able to re-establish an identical socket in a short period of time (two minutes according to the book). So my understanding is: join me to conn...
