MQTT is an ISO standard (ISO/IEC PRF 20922) [1] publish–subscribe-based messaging protocol.It works on top of the Internet protocol suite TCP/IP. It is designed for connections with remote locations where a "small code footprint" is required or the network bandwidth is limited.
An MQTT broker is a server that receives all messages from the clients and then routes the messages to the appropriate destination clients. [17] An MQTT client is any device (from a microcontroller up to a full-fledged server) that runs an MQTT library and connects to an MQTT broker over a network. [18]
WAMP also targets the IoT, where it is used in the same way as MQTT [18] as a light and efficient medium to orchestrate clusters of connected objects. The implementations in various languages make it suitable to control and monitor small devices such as the Raspberry Pi (in Python) or the Tessel [19] (in JavaScript).
Node-RED has gained traction in the industrial internet of things (IIoT) and edge computing sectors. [8] [9] [10] Node-RED's open-source nature and large community have led to the creation of over 4000 connectors [11] supporting a wide range of data sources and protocols such as Modbus, OPC-UA, Siemens S7, and MQTT.
Internet of things (IoT) describes devices with sensors, processing ability, software and other technologies that connect and exchange data with other devices and systems over the Internet or other communication networks.
AMQP is a binary application layer protocol, designed to efficiently support a wide variety of messaging applications and communication patterns. It provides flow controlled, [3] message-oriented communication with message-delivery guarantees such as at-most-once (where each message is delivered once or never), at-least-once (where each message is certain to be delivered, but may do so ...
The WebSphere Message Broker Transfer License for WebSphere Enterprise Service Bus enables customers to exchange some or all of their WebSphere Enterprise Service Bus license entitlements for WebSphere Message Broker license entitlements. Following the license transfer, entitlement to use WebSphere Enterprise Service Bus will be reduced or cease.
Network address translation between a private network and the Internet. Network address translation (NAT) is a method of mapping an IP address space into another by modifying network address information in the IP header of packets while they are in transit across a traffic routing device. [1]
