1. Proposal for OID-based M2M Node ID Group Name: WG2 Architecture at TP#8 (Miyazaki, December 2013) Source: Yong-Suk Park, KETI, yspark@keti.re.kr Meeting Date: 2013-12-09 Agenda Item: TBD (Contribution on M2M Node ID)

2. What is OID? OID (Object Identifier) – A globally unique value associated with an object to unambiguously identify it (ITU-T Recommendation X.680|ISO/IEC 8824-1) Object Types – ITU-T SG(Study Group) number, country, standard, encryption algorithm, network, protocol command, etc.  Anything {0 1 17} = ITU-T Study Group 17 {1 2 410} = Korea {1 0 15961} = ISO/IEC 15961 {1 2 410 200004 1 2} = HAS-160 hash algorithm {0 3 4500} = Korea (Rep. of) HiNET-P (Korea Telecom) {1 0 15961 126 7} = ReadSingleObjectCommand (rfid-data-protocol) © 2013 oneM2M Partners oneM2M-ARC-2013-0529 2

3. OID Structure Hierarchical structure based on the “OID Trees” Root is unnamed. The first arc consists of 3 values: 0, 1, 2 Each arc is managed individually or jointly by international standards bodies © 2013 oneM2M Partners oneM2M-ARC-2013-0529 3 Root 0 (ITU-T)1 (ISO)2 (Joint ISO/ITU-T) 12... 4012 1 27... 40 450 480 481 4101 Root Arc 1 st Arc 2 nd Arc 3 rd Arc An “Arc” is a placeholder for representation in the OID hierarchical tree structure and the number of digits in each “Arc “ is variable.

6. Why use OID? Standardized International Identification System – Unlike other identification schemes, OID is a globally unique identification system based on international standard (applicable to any industry, any country) ITU-T X.660 | ISO/IEC 9834-1 (2008), General procedures and top arcs of the ASN.1 Object Identifier tree ITU-T X.662 | ISO/IEC 9834-3 (2008), Registration of object identifier arcs beneath the top-level arc jointly administered by ISO and ITU-T ITU-T X.665 | ISO/IEC 9834-6 (2004), Registration of application processes and application entities ITU-T X.666 | ISO/IEC 9834-7 (2008), Joint ISO and ITU-T registration of international organizations Easily expandable due to the hierarchical structure of the OID Tree The concept of “registration” can be applied to the identifier of a particular object – Conflict between identifiers can be avoided – Enables easy management and control – Infrastructure exists for OID Directory/Resolution (DNS like) © 2013 oneM2M Partners oneM2M-ARC-2013-0529 6
