  5. TCP Operation The transport layer is responsible for the reliable transport of and regulation of data flow from source to destination.

  6. Synchronization or Three-Way Handshake

  7. Denial-of-Service Attacks

  8. Simple Windowing

  9. TCP Sequence and Acknowledgment Numbers

  10. Positive ACK • Acknowledgement is a common step in the synchronization process which includes sliding windows and data sequencing.

  11. Protocol Graph: TCP/IP

  12. UDP Segment Format

  13. Port Numbers

  14. Telnet Port Numbers

  15. Reserved TCP and UDP Port Numbers

  16. Ports for Clients • Whenever a client connects to a service on a server, a source and destination port must be specified. • TCP and UDP segments contain fields for source and destination ports.

  17. Port Numbering and Well-Known Port Numbers • Port numbers are divided into three different categories: • well-known ports • registered ports • dynamic or private ports

  18. Port Numbers and Socket

  19. Comparison of MAC addresses, IP addresses, and port numbers • A good analogy can be made with a normal letter. • The name on the envelope would be equivalent to a port number, the street address is the MAC, and the city and state is the IP address.
