wide area network technology

network protocol that builds a loop-free logical topology for Ethernet networks

Remote Authentication Dial-In User Service (RADIUS) is a networking protocol that provides centralized authentication, authorization, and accounting (AAA) management for users who connect and use a network service. RADIUS was developed by Livingston Enterprises in 1991 as an access server authentication and accounting protocol. It was later brought into IEEE 802 and IETF standards.

AppleTalk is a discontinued proprietary suite of networking protocols developed by Apple Computer for their Macintosh computers. AppleTalk includes a number of features that allow local area networks to be connected with no prior setup or the need for a centralized router or server of any sort. Connected AppleTalk-equipped systems automatically assign addresses, update the distributed namespace, and configure any required inter-networking routing.

Z-Wave is a wireless communications protocol used primarily for residential and commercial building automation. It is a mesh network using low-energy radio waves to communicate from device to device, allowing for wireless control of smart home devices, such as smart lights, security systems, thermostats, sensors, smart door locks, and garage door openers. Z-Wave Long Range (ZWLR) is a sub-GHz wireless communication protocol designed to extend smart home connectivity, offering a range of up to 1.5 miles. It enables direct hub-to-device communication, supports up to 4,000 nodes per network, and

UUCP (Unix-to-Unix Copy) is a suite of computer programs and protocols allowing remote execution of commands and transfer of files, email and netnews between computers.

means of transporting data over a packet-switched network so as to emulate a dedicated physical link between nodes

method of designing modular communication protocols in which separate functions are abstracted from their underlying structures

thumb|A DMX splitter/buffer. It allows a DMX universe from one source to be repeated to several chains of devices, in order to avoid signal degradation due to long cable runs.

implementation of a computer networking protocol suite

MQTT is a lightweight, publish–subscribe, machine-to-machine network protocol for message queue/message queuing service. It is designed for connections with remote locations that have devices with resource constraints or limited network bandwidth, such as in the Internet of things (IoT). It must run over a transport protocol that provides ordered, lossless, bi-directional connections—typically, TCP/IP. It is an open OASIS standard and an ISO recommendation (ISO/IEC 20922).

Preboot Execution Environment

model of communication where one device or process has unidirectional control over one or more other devices

network time synchronization protocol

proprietary networking architecture for IBM mainframes and minicomputers

automated process of negotiation that dynamically sets parameters of a communications channel established between two entities before normal communication over the channel begins

communications standard

ZeroNet is a decentralized web-like network of peer-to-peer users, created by Tamas Kocsis in 2015. The programming for the network was based in Budapest, Hungary. It is built in Python and fully open source. Instead of having an IP address, sites are identified by a public key (specifically a bitcoin address). The private key allows the owner of a site to sign and publish changes, which propagate through the network. Sites can be accessed through an ordinary web browser when using the ZeroNet application, which acts as a local webhost for such pages. In addition to using bitcoin cryptography,

BACnet is a communication protocol for building automation and control (BAC) networks. It is defined by ANSI/ASHRAE 135 and ISO 16484-5.

DECnet is a suite of network protocols created by Digital Equipment Corporation. Originally released in 1975 in order to connect two PDP-11 minicomputers, it evolved into one of the first peer-to-peer network architectures, thus transforming DEC into a networking powerhouse in the 1980s. Initially built with three layers, it later (1982) evolved into a seven-layer OSI-compliant networking protocol.

communications protocol allowing files to be transferred to or from USB-attached devices such as cameras and smartphones

FlexRay is an automotive network communications protocol developed by the FlexRay Consortium to govern on-board automotive computing. It is designed to be faster and more reliable than CAN and TTP, but it is also more expensive. The FlexRay consortium disbanded in 2009, but the FlexRay standard is now a set of ISO standards, ISO 17458-1 to 17458-5.

communication protocol for streaming data over the Internet

OpenFlow is a communications protocol that gives access to the forwarding plane of a network switch or router over the network.

Stunnel is an open-source multi-platform application used to provide a universal TLS/SSL tunneling service.

data transmission method in packet switching networks in which each data unit is individually addressed and routed

communications protocol in which no information is retained by either sender or receiver

CANopen is a communication protocol stack and device profile specification for embedded systems used in automation. In terms of the OSI model, CANopen implements the layers above and including the network layer. The CANopen standard consists of an addressing scheme, several small communication protocols and an application layer defined by a device profile. The communication protocols have support for network management, device monitoring and communication between nodes, including a simple transport layer for message segmentation/desegmentation. The lower level protocol implementing the data li
