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.
Network protocols defines a language of rules and conventions for communication between network devices.
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.
PPPoE (Point-to-Point Protocol over Ethernet) is a network protocol sometimes used by broadband modems for connecting to DSL Internet service.
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.
The Hypertext Transfer Protocol - HTTP - provides a standard for Web browsers and servers to communicate. HTTP is an application layer network protocol built on top of TCP.
ATM is a high-speed networking standard designed to support both voice and data communications. ATM operates at the data link layer (OSI Layer 2) over either fiber or twisted-pair cable.
The Spanning Tree Protocol implements a standard algorithm to prevent redundant transmission of data along intermediate hops between a source and destination host.
Network Time Protocol is a server based system to synchronize time of day clocks computer across the Internet.
Token Ring is a data link technology for local area networks (LANs). Unlike all other standard forms of LAN interconnects, Token Ring maintains one or more common data frames that continuously circulates through the network. Token Ring was developed by IBM during the 1980s as an alternative to Ethernet.
SOCKS is an Internet protocol designed to allow clients to communicate with proxy servers (or VPN servers) through network firewalls.
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).
Frame relay is a network protocol designed for use on Wide Area Networks (WANs). Frame relay works over fiber optic or ISDN lines.
FireWire (IEEE 1394) is a high-speed serial networking standard for connecting a computer to a nearby peripheral device such as a digital video camera.
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 is a standard TCP/IP protocol for network management including the monitoring and control of network devices.
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.
The SS7 protocol provides mechanisms for exchanging special-purpose messages on public telephone networks.
SCTP is an alternative transport protocol to TCP and UDP. Some higher level network protocols like SIP and SS7 use SCTP.
Ethereal is a high quality utility program commonly used by students, researchers and some companies to monitor network traffic.
This book features in-depth technical background on fundamental network protocols such as TCP, ICMP and ARP.
