An Architectural Framework for the Internet of Things (IOT)
|Publication Date:||21 May 2019|
This standard defines an architecture framework description for the Internet of Things (IoT). The architecture ontology and methodology of the framework architecture conforms to the international standard ISO/IEC/IEEE 42010:2011.
The architecture framework description is motivated by concerns commonly shared by IoT system stakeholders across multiple domains (transportation, healthcare, Smart Grid, etc.). This standard provides a conceptual basis for the notion of things in the IoT and then elaborates the shared concerns as a collection of architecture viewpoints that form the body of the framework description.
The IoT is predicted to become one of the most significant drivers of growth in many technology markets. The architectural framework defined in this standard will promote cross-domain interaction, aid system interoperability and functional compatibility, and further fuel the growth of the IoT market. The standard will address stakeholder concerns to help them build a connected world that can interoperate while meeting both the needs of enterprises and society for trustworthiness of IoT systems. The adoption of a unified approach to the development of IoT systems will reduce industry fragmentation and create a critical mass of multi-stakeholder activities around the world.
The motivation for the standard as informed by stakeholder concerns and desired outcome is to build stakeholder confidence through the following:
a) Provide a framework for vendors to build conformant, interoperable, secure, IoT systems that can span multiple application domains.
b) Provide a framework for buyers to make comparisons and assessments of such systems.
c) Provide a framework for system designers to accelerate design, implementation, and deployment processes of such systems.
Business goals trigger and frame system concerns and thus the system architecture. In fact, the U.S. National Institute of Standards and Technology (NIST) CPS Public Working Group generated a list of concerns for cyber-physical systems (CPS) as listed in the Framework for Cyber-Physical Systems (NIST SP 1500-201 [B88]). The framework includes a business aspect that defines "concerns about enterprise, time to market, environment, regulation, cost, etc." The concerns in the present document as derived from the NIST concerns incorporate business elements that acknowledge that systems need to be integrated into business processes to successfully meet the business goals. There is no common approach to addressing the business viewpoint and, therefore, this standard does not include a business architecture viewpoint. The relevance of the business goal of value creation and the desire for differentiable value propositions in the market are implied throughout the standard. Business goals are important for any viable system architecture.
This document provides both a normative part (Clause 6) with the architecture viewpoints intended to be the basis for describing the architecture for an IoT system, and an informative part (Clause 7) with examples of architecture descriptions associated with architecture views that conform to the architecture viewpoints.
