Hi
I was reading the network book the other day and it said TCP was a connection-oriented protocol, and I'm now puzzled with what connection-oriented means in this instance.
I understand what connetion-oriented means in general. In the data link layer, connection-oriented communication such as ATM, Frame-Relay and telephone conversation set up the communication path first, transfer the data along that path, and tear down the path after the data transfer is done. The data flows on the same path which is set up in advance. It's very clear what connection oriented means in such a case, but I can't see a clear picture about connection-oriented in transport layer, TCP.
TCP(or any transport layer entities) doesn't specify the communication path, right ? How could TCP be connection-oriented ?
