This video demonstrates how protocol analysis works.
- [Instructor] There are two dominate network models … in use today. … Both of them adopt layered architecture. … One is Open Systems Interconnection or OSI, … and the other is … Transmission Control Protocol/Internet Protocol or TCP/IP. … Each layer of these mainstream network models … specifies protocols of its own. … For instance, the transport layer … features two major protocols … called TCP and User Datagram Protocol or UDP. … TCP is connection-oriented protocol … which means that it creates a reliable connection … between hosts and ensures that packets arrive … in order and free of errors. … TCP also retransmits packets … if they fail to show up on the other side. … For this type of bullet-proof communication to happen, … the TCP protocol needs to explicitly establish … a connection and break it up. … Three-way handshaking is the process TCP adopts. … To create a connection, a host sends a synchronized, … or SYN segment, in a transport layer header. … The receiving side can accept the SYN request …
