IEEE P2413 -‐ Standard for an Architectural Framework for the Internet of Things (IoT) Meeting report – January 2015 The January 2015 meeting of the IEEE P2413 Working Group was held on 22-‐23 January in Taipei Taiwan hosted by Institute for Information Industry (III). For more information on III, please visit http://web.iii.org.tw/. 19 representatives from 13 companies attended the meeting. The Group reviewed reports from the Sub-‐Working Groups (SWGs) • The Scope of Applicability SWG had a number of fruitful discussions. including a review of the models proposed by Cisco at the IoT World Forum (presented by CISCO during the SWG teleconference on December 15, 2014) , and the Purdue model presented in this session by Cliff Whitehead (Rockwell Automation). • The Networking SWG proposed the definition of the scope of work for SWG efforts that was later updated and approved by the WG: o Approach: § Take the major standards/fora/industry body of work identified in the Standardization Landscape SWG, and extract any identified networking information, e.g. • network topologies • protocols • security • performance (parametric) • Application aware routing and media selection • Application aware power management and profiling/shaping • Application aware resource constraints/implementation § Collate information by IoT domain and assemble a key metrics/parameters matrix, e.g. • messaging requirements (frequency, size, duplex, encryption etc.) • performance (latency, jitter, determinism) • availability (redundancy, resilience, recovery) • connectivity (wired/wireless, range, LoS etc.) • constraints (power, memory, CPU etc.) • To accelerate the development process, the Group launched a new Reference Model Sub-‐Working Group, with the following scope of work: o Analyse input from other groups that have worked on reference models (ITU-‐T, ISO/IEC, IoT-‐A, etc.) o Benchmark reference models against the goals of this standard o Analyse proposals generated by P2413 members o Devise process for sorting, mapping, clustering, tracing and unifying the above proposals. The Group accepted the following as an issue “how resource-‐oriented profiles and architectures can be realized with IEEE P2413 using a service oriented approach”. The Group will be reviewing submissions that attempt to solve this issue. The Group reviewed and updated the project plan with estimated dates: • Collection and Unification of Requirements (currently in progress) • Drafting of Reference Model (estimated completion by October 2015) • Drafting of Reference Architecture and Systems Model (estimated completion by the end of 2015) • Sponsor Ballot process on draft standard (estimated to begin in mid-‐2016.) The Group proposed exploring the possibility of an advisory group under the IEEE-‐
SA Industry Connections activity (http://standards.ieee.org/develop/indconn/) that could potentially be done in collaboration with the IEEE IoT Initiative (http://iot.ieee.org/). The goal would be to provide a mechanism for gathering requirements and use cases from academia and other organizations. The Group adopted the following definitions and approaches: 1) The definition of the “Thing” Apps & Services
Security
The “Thing”
Function/Method
Properties
Information Exchange
Notes: • Things, Apps, and Services can be integrated into what would be abstracted as a “Thing” Information exchange could be “horizontal” (subscribe/publish as an example) or vertical, or both Properties could be real or virtual •
•
2) An approach to the aggregation of things: IEEE P2413 Application Framework
Applications and Services
