Network Protocols

Network Protocols Visually

Interactive visualization of network protocols including HTTP, FTP, SMTP, DNS, and more. Learn their functions, data flow, and communication patterns through dynamic simulations with real-world data.

HTTP/HTTPS FTP/SFTP SMTP/POP3 DNS TCP/UDP TLS/SSL

Understanding Network Protocols

1
Application Layer
Protocols that provide network services directly to end-user applications such as HTTP, FTP, SMTP, and DNS.
2
Transport Layer
Protocols that ensure complete data transfer with TCP providing reliable delivery and UDP offering connectionless communication.
3
Network Layer
Protocols responsible for packet forwarding and routing, including IP which determines the best path for data delivery.
4
Data Link & Physical
Protocols that handle communication between adjacent network nodes and the physical transmission of data bits.
