nagement and provisioning purposes and for analyzing the suitability of different device provisioning and management tools for each class. ETSI Standardization Work ETSI http://www.etsi.org has established an M2M technical committee to develop standards for M2M communications. The committee has developed a set of specifications for M2M listed below, and is working on additional documents such as for M2M interfaces. Deploying IPv6 in 3GPP Networks Service requirements: Defines requirements for M2M communications, management (e.g., configuration), functionality (e.g., data collection), security (e.g., authentication, integrity), and for naming, numbering and addressing - allowing for both IPv4 and IPv6 [57]. Functional architecture: Defines high level architecture, functional architecture, key reference points, identification and addressing, security, bootstrapping, provisioning, and resource management, among many other smaller topics. This is the main document for ETSI's M2M documentation [90]. mla, dla, and mId interfaces: Specifies in detail the mla, dIa, and mId reference points introduced in the 'Functional architecture' document [91]. Smart metering use cases: Describes the M2M application for smart metering in a very detailed manner [58]. In this section we will not describe in more depth how ETSI sees the M2M, as that could be a subject of a dedicated book. The standards by ETSI are available for free download, and hence we recommend interested readers to follow the references for more details. OneM2M OneM2M http://www.onem2m.org is a newly founded organization, launched on 24 July 2012, whose purpose is to gather M2M related organizations together to develop technical specifications for a common M2M service layer that would enable M2M devices to interoperate at a global scale. The OneM2M was launched by seven standards defining organizations: Association of Radio Industries and Businesses (ARIB), Alliance for Telecommunications Industry Solutions (ATIS), China Communications Standards Association (CCSA),
