GB/T 36444-2018Information technology—Open systems interconnection—Simple directory protocol and service (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

Introduction

With the development of the Internet of Things industry and technology, the interconnection of heterogeneous IoT application systems has become the main question that restricts the continued development of the Internet of Things. One of the questions. In order to address the interconnection of heterogeneous systems, many industry organizations have already standardized on resource interconnection, including the use of UML and Business process models and software components for public modeling facilities and switching facilities such as XML. The standards that have been developed are mainly dedicated to a certain line. Industry-wide service agreements or data exchange standards, such as the Alarm Protocol (CAP) for alarm systems, a description language for electronic devices (EDDL), Data Exchange Standard (oBIX) and Physical Description Language (PML) for open buildings.

Directory service technology is environment-independent and is used to solve technologies and methods for open system interconnection and heterogeneous system integration and sharing. In order to promote The resources in the entire Internet of Things are effectively shared, and the heterogeneous, complex and complex intellectual property of the Internet of Things is limited, and the physical location is limited. Based on the characteristics of state changes, a simplified directory protocol and service for facilitating the interconnection of heterogeneous IoT systems are proposed to solve the sharing of object information in the Internet of Things.

This standard uses a directory structure to store resource information across industries, standardizes the information resource description model in the Internet of Things, and provides standardized services. The service interface realizes the unified naming, management and service of resources, and finally plays an auxiliary specification and reference role for the following information interconnection.

--- IoT applications and smart objects with different physical characteristics;

--- IoT applications and smart objects managed by different (industry) agreements;

--- IoT applications and smart objects with different service requirements;

--- IoT applications and smart objects of different complexity.

This standard refers to GB/T 16264 definition of directory access protocol, is a subset of it but has some differences. First, the combination of Internet of Things resources Features such as limited power capability, adopting a light-weight directory protocol with low functional complexity and simple implementation, which is convenient for lightweight processing of information;

The content is all directed to the field of Internet of Things. The content of the specification has the characteristics of the Internet of Things, facilitating the interconnection of IoT applications and smart objects.

In addition, in other non-Internet of Things, this standard can also be applied to the construction of resource descriptions and access services.

1 Scope

This standard specifies the IoT directory information base and simplified directory access services.

This standard applies to the description, storage, distribution, and acquisition of information on heterogeneous IoT systems.
