Network Protocols

Network protocols like HTTP, TCP/IP, and SMTP provide a foundation that much of the Internet is built on. Find out more about these protocols and how they work.

  2. FTP
  3. DNS - Domain Name System
  4. TCP and UDP
  5. Link Layer Network Protocols (5)

What is a Network Protocol?
Network protocols defines a language of rules and conventions for communication between network devices.

What Is Packet Switching?
Packet switching is a method used by network protocols including IP and Frame Relay to deliver data across a computer network connection in individually delivered small pieces.

Introduction to MAC Addresses
In computer networking, the Media Access Control (MAC) address is just as important as an IP address. Learn more about how MAC addressing works on Ethernet, Wi-Fi and Bluetooth networks.

ARP - Address Resolution Protocol
ARP converts an IP address to its corresponding physical network address. ARP is a low-level protocol usually implemented in the device drivers of network operating systems. ARP is most commonly utilized on Ethernet networks.

PPPoE
PPPoE (Point-to-Point Protocol over Ethernet) is a network protocol sometimes used by broadband modems for connecting to DSL Internet service.

Spanning Tree Protocol
The Spanning Tree Protocol implements a standard algorithm to prevent redundant transmission of data along intermediate hops between a source and destination host.

NTP - Network Time Protocol
Network Time Protocol is a server based system to synchronize time of day clocks computer across the Internet.

SOCKS
SOCKS is an Internet protocol designed to allow clients to communicate with proxy servers (or VPN servers) through network firewalls.

UWB
Ultra-wideband - UWB - is a communication method used in wireless networking to achieve high bandwidth connections with low power utilization. Originally designed for use in commercial radar systems, UWB technology is gradually being adopted in consumer electronics and wireless personal area networks (PANs).

X.25
X.25 is a standard suite of protocols used for packet switching and delivery between networks. The X.25 protocols works at the physical, data link, and network layers (Layers 1 through 3) of the OSI model.

SNMP - Simple Network Management Protocol
SNMP is a standard TCP/IP protocol for network management. Network administrators use SNMP to monitor network availability and performance, and control devices to help recover from technical issues.

H.323
H.323 is a protocol standard for multimedia communications. H.323 was designed to support real-time transfer of audio and video data over packet networks.

SS7 - Signaling System 7
The SS7 protocol provides mechanisms for exchanging special-purpose messages on public telephone networks.

Ethereal Network Protocol Analyzer
Ethereal is a high quality utility program commonly used by students, researchers and some companies to monitor network traffic.

"Internet Core Protocols - The Definitive Guide"
This book features in-depth technical background on fundamental network protocols such as TCP, ICMP and ARP.

Introduction to 60 GHz Wireless Network Protocols
The two most prevalent 60 GHz wireless networking technology standard are WirelessHD and WiGig. Compared to Wi-Fi and other forms of wireless, the 60 GHz protocols have some compelling advantages but also limitations.

Guide to Wireless Network Protocols
Beside Wi-Fi, a wide range of other wireless communications protocols are in use on today's computers networks. How many can you name?
