ETSI ETSI TR 118 503 V1.0.0 (2015-04) 5 1 Scope The present document provides an evaluation of existing M2M-related Architecture work undertaken by the

14、 founding partners of oneM2M, including: the Association of Radio Industries and Businesses (ARIB) and the Telecommunication Technology Committee (TTC) of Japan; the Alliance for Telecommunications Industry Solutions (ATIS) and the Telecommunications Industry Association (TIA) of the USA; the China

15、Communications Standards Association (CCSA); the European Telecommunications Standards Institute (ETSI); and the Telecommunications Technology Association (TTA) of Korea. Common Functional Entities and Reference Points are identified, as well as critical differences. New functionality will not be co

16、nsidered as part of this study. The present document is intended to ensure a common understanding of existing M2M Architectural approaches, in order to facilitate future normative work resulting in oneM2M Technical Specifications. The present document has been prepared under the auspices of the oneM

It is a style of API interface. When the API of a system qualifies RESTs features, we say the system is RESTful. REST was first described by R.T. Fielding in his Doctor
