ccna syllabus pdf.. The source device sends a UDP data segment to the target device and receives a response.. The source device sends a UDP data segment to the target device. The exact scenario that will occur depends on the application being used. How do you end a UDP session? This also varies from application to application: . . the application can send a message indicating that the session has ended, which can be included in the data payload; . Use an idle timeout, i.e. if no data segment is received within a predetermined period of time, the application considers the session to have ended.TCP, on the other hand, is much more complex and uses a predetermined state machine. A predefined state machine defines mechanisms for starting a state (establishing a TCP session), maintaining a state (sustaining a TCP session), and ending a state (ending a TCP session). The next few subsections describe these TCP mechanisms in more depth.8.4.1 TCP's Three HandshakesWhen using a reliable TCP session, before sending a message to another host, the host must establish a connection through a handshake process, the steps of which are shown in Figure 8.3.In Figure 8.3, PC-A wants to send data reliably to PC-B over TCP. To do this, PC-A must first establish a session to PC-B: these two hosts establish a reliable session through three handshakes. The three-handshake process consists of the following three steps.Transferring DataFigure 8.3 Establishing a reliable connection: three handshakesThe source device sends a synchronization (SYN) data segment to the target device (which sets the SYN control flag in its TCP header), indicating that the source device wants to establish a reliable session.The target device responds with a data segment with the Acknowledge and Synchronize flags set. The acknowledgement indicates that the SYN data segment was received from the source device, while the SYN flag indicates that the session can now be established (the target device is willing to establish a session.) These two flags in the TCP header are commonly referred to as SYN/ACK, and they are sent over the same data segment.
