Episode 67: Connection-Oriented vs. Connectionless — Making Sense of Transport Styles
This episode explains the difference between connection-oriented and connectionless communication, two fundamental transport styles. Connection-oriented communication, as seen with TCP, establishes a session, ensures data arrives in order, and retransmits lost packets. Connectionless communication, as seen with UDP, sends data without establishing a dedicated session, offering lower latency at the expense of reliability. Recognizing this distinction is a key exam requirement.
The discussion expands with practical examples, such as using TCP for financial transactions where accuracy is mandatory, and UDP for voice or video applications where speed is prioritized. Troubleshooting considerations include identifying when an application expects reliable transport but is configured to use UDP, or when excessive retransmissions in TCP degrade performance. Understanding these transport styles ensures you can analyze traffic flows and apply correct solutions in exam scenarios and professional practice.
