- Agenda for this video

- Connection Oriented vs Not Connection Oriented

- TCP is Reliable -- but what does that mean?

- Confirmation of Data Delivery

- Application is Aware of Errors

- Data Ordering and Sequence Numbers

- Notice I didn't say UDP is not reliable

- Flow Control & Bandwidth Utilization

- TCP has More Overhead, UDP has Less Overhead

- UDP Header, 4 fields, 8 bytes

- TCP Header, 11 fields, 20-60 bytes

- Dispelling Myths about TCP and UDP

- UDP is Faster ... Not Exactly -- Myth 1

- TCP is more Secure ... WRONG -- Myth 2

- UDP is Unreliable ... NOPE -- Myth 3

- TCP is Guaranteed Delivery ... Well, not really =/ -- Myth 4

- There is so much more to discuss with TCP

- Summary

Description:
