For now only OCPP 1.6 can be fully tested and certified. OCPP versions older than OCPP 1.6 (such as OCPP 0.7, OCPP 1.2, and OCPP 1.5) as well as OCPP 2.0 are not covered under the current OCPP certification program. Open Charge Alliance has defined a set of test procedures and test plans for the certification compliance.
In computing, Open Data Protocol (OData) is an open protocol that allows the creation and consumption of queryable and interoperable Web service APIs in a standard way. Microsoft initiated OData in 2007. [1] Versions 1.0, 2.0, and 3.0 are released under the Microsoft Open Specification Promise.
HTTP (Hypertext Transfer Protocol) is an application layer protocol in the Internet protocol suite model for distributed, collaborative, hypermedia information systems. [1] HTTP is the foundation of data communication for the World Wide Web , where hypertext documents include hyperlinks to other resources that the user can easily access, for ...
When a Transport Layer Security (SSL or TLS) connection starts, the record encapsulates a "control" protocol—the handshake messaging protocol (content type 22). This protocol is used to exchange all the information required by both sides for the exchange of the actual application data by TLS.
Generally these systems operated together with a simple command processor that allowed users to type in English-like commands, and receive output. The best-known examples are SQL from IBM and QUEL from the Ingres project. These systems may or may not allow other applications to access the data directly, and those that did use a wide variety of ...
Transport Layer Security (TLS) is a cryptographic protocol designed to provide communications security over a computer network, such as the Internet.The protocol is widely used in applications such as email, instant messaging, and voice over IP, but its use in securing HTTPS remains the most publicly visible.
The CELLPAC [22] protocol developed 1991–1993 was the trigger point for starting in 1993 the specification of standard GPRS by ETSI SMG. Especially, the CELLPAC Voice & Data functions introduced in a 1993 ETSI Workshop contribution [ 23 ] anticipate what was later known to be the roots of GPRS.
Some devices are transmit-only; others are receive-only. Chip selects are sometimes active-high rather than active-low. Some devices send the least-significant bit first. Signal levels depend entirely on the chips involved. And while the baseline SPI protocol has no command codes, every device may define its own protocol of command codes.
