TCP Three-Way Handshake

対象: Software Engineerカテゴリ: Computer Science

説明

Animates the complete TCP connection lifecycle between a client and server: the three-way handshake (SYN, SYN-ACK, ACK), data transfer phase, and four-way connection teardown (FIN, ACK, FIN, ACK). Each packet is labeled with its flags and sequence/acknowledgment numbers, and a timeline diagram tracks the full exchange.

TCP Three-Way Handshake

Description

Animates the complete TCP connection lifecycle between a client and server: the three-way handshake (SYN, SYN-ACK, ACK), data transfer phase, and four-way connection teardown (FIN, ACK, FIN, ACK). Each packet is labeled with its flags and sequence/acknowledgment numbers, and a timeline diagram tracks the full exchange.

Phases

# Phase Name Duration Description
1 Intro 3s Title, client and server boxes displayed
2 SYN 5s Client sends SYN with seq=0; packet travels to server
3 SYN-ACK 5s Server responds SYN-ACK with seq=0, ack=1
4 ACK 4s Client sends ACK; connection established
5 Data Transfer 8s Bi-directional data packets shown briefly
6 FIN Teardown 12s Four-way teardown: FIN→ACK→FIN→ACK
7 Timeline 8s Full timeline diagram shown from top to bottom
8 Outro 3s "Connection closed" displayed
