Study Notes
XMPP
- XMPP stands for Extensible Messaging and Presence Protocol.
- XMPP is an open standard protocol.
AMQP
- AMQP stands for Advanced Message Queuing Protocol.
- The basic unit of data in the AMQP protocol is called a frame.
- The exchange types in AMQP are Direct, Fan-out, Topic, and Header.
MQTT
- The full form of MQTT is Message Queue Telemetry Transport.
- In MQTT, a message broker controls the publish-subscribe messaging pattern.
- Publishers in MQTT are lightweight sensors.
- The methods in MQTT include Connect, Disconnect, Subscribe, Unsubscribe, and Publish.
CoAP
- CoAP has been designed for Machine to Machine (M2M) applications such as smart energy and building automation.
- Similar to HTTP, CoAP utilizes GET, PUT, PUSH, DELETE message requests to retrieve, create, update, and delete, respectively.
IoT Networks
- IoT networks can be classified into two types: Non-Beacon Enabled and Beacon Enabled.
OSI Model
- The OSI model has 7 layers.
IPv4
- The “Destination Address” in the IPv4 packet represents the address of the destination node in the network.
