Quick definition: Transmission Control Protocol (TCP) is a communications standard that software applications use to exchange data. It sets the parameters for the exchange, confirms what is being sent, where it’s coming from, where it’s going, and whether or not it arrived correctly.

A Comprehensive Guide to IoT Protocols
When network entities like servers, gateways, routers, applications, and connected devices interact, protocols give them a shared language. A protocol is a set of rules both network entities must have in common in order to communicate. It governs what their interactions look like, what values and attributes can be transmitted, how they’re received and processed, what security methods will be used, and more.
What Is Transport Layer Security (TLS)?
As the name implies, Transport Layer Security is a protocol that gets implemented on the transport layer of a network to encrypt data transmitted via HTTP, FTP, XMPP, etc. TLS is typically implemented in conjunction with protocols like Transmission Control Protocol (TCP), which prioritizes accuracy over speed. However, in some cases it can be used with connection less protocols like User Datagram Protocol (UDP) - then using a slight variant called DTLS.
What Is Open Charge Point Protocol (OCPP)?
Why use OCPP? OCCP defines how charge stations and central management systems transmit commands like start and stop power, as well as diagnostic data such as how much power is being consumed or if there are any errors. By standardizing these transmissions, OCCP ensures that charge stations and central management systems from different suppliers can communicate.
