ISO评估未来网络对物联网的影响


国际智慧学会未来网络信息中心第14008号文件中,介绍了物联网国际标准的新动向。其中特别说明了未来网络与物联网之间关联研究越来越受重视。下面是国际标准组织ISO/IEC JTC 1/SC 6(未来网络标准项目单位)向JTC 1/SWG 5 (物联网研究组)递交的联络报告,初步介绍了未来网络标准化情况,并指出了未来网络可能对物联网的影响。这份报告由中国香港的SC6专家张庆松博士编写。

SC 6 Future Network and IoT(M2M)

1. Overview of SC 6 Future Network

Future Network (FN) is a ISO/IEC JTC 1/SC 6/WG 7 project started in 2007. The initial proposal was from Korea NB. It aims at creating a series of new network architecture and protocol standards based on a clean slate design approach. The underline assumption is that the existing network architectures have structural limitations, that evolutionary approach is unable to resolve all the issues, and that ISO/IEC should create a new type of network whose design takes into the consideration of the requirement of technological and social needs for more secure, more efficient and more economical information exchange and network communication.

SC 6's FN project development plan has three stages. Stage 1 is the study of problems and overall requirements, stage 2 is the establishment of FN architectre/framework and stage 3 is on the development of FN network protocols.

SC 6-FN Stage 1 is now almost complete. The project has been working on a series of technical reports (ISO/IEC TR 29181) since 2009. It consists of 7 parts under the general title "Future Network — Problem statement and requirements":

?TR 29181-1 - Part 1: General Aspects (published 2012)

?TR 29181-2 - Part 2: Naming and Addressing (in DTR stage)

?TR 29181-3 - Part 3: Switching and Routing (published 2013)

?TR 29181-4 - Part 4: Mobility (published 2013)

?TR 29181-5 - Part 5: Security (in DTR stage)

?TR 29181-6 - Part 6: Media Distribution (published 2013)

?TR 29181-7 - Part 7: Service Composition (published 2013)

SC 6 WG 7 also established close collaboration with ITU-T SG13, SG17 and SG2 on FN related issues.

2. TR 29181 Summaries

ISO/IEC TR 29181-1:2012 describes the definition, general concept, problems and requirements for Future Network (FN). It also discusses a milestone for standardization on FN. The scope includes: motivation of FN; definition, general concept, and terminologies of FN; services and applications in FN; problems with current networks; design goals and high-level requirements for FN; milestones for standardization on FN.

ISO/IEC TR 29181-2 describes the general characteristics of Future Network Naming and Addressing Schemes including problem statement, design objectives, gap analysis, and development directions.  The topics include: the characteristics and deficiencies of existing NAS in existing network; a list of major technical challenges to assure that the FN-NAS will be able to provide solid technical support from the base level to meet the objectives of FN; the general characteristics of Future Network are discussed and their impact on NAS design; examines the gap between existing network NAS and future network performance expectations; specify objectives and principles for NAS design.

ISO/IEC TR 29181-3:2013 contains the problem statement and requirements for switching and routing in the Future Network, in particular: 1, description of the requirements for carrying data over digital networks; 2, description of the ways in which these requirements are not satisfied by current networks; 3, functional architecture for switching and routing in the Future Network; 4, and requirements for control plane information flows for finding, setting up, and tearing down routes. The requirements in 4 include support for both current ("legacy") and future ("new") switching technologies, to aid the transition between them.

ISO/IEC TR 29181-4:2013 describes the problem statements of current network and the requirements for Future Network in the mobility perspective. It mainly specifies problems of the current network in mobile environment, and requirements for mobility support in Future Network. In addition, ISO/IEC TR 29181-4:2013 gives information on existing mobility control schemes in the current network, examples of high-level mobility control architecture for Future Network, distributed mobility control in the Proxy Mobile IPv6 networks, and additional considerations for Future Network mobility.

ISO/IEC TR 29181-5 describes the problem statements of current network and the requirements for Future Network in the security perspective. It mainly specifies Problems of the current network in security environment and requirements for security support in Future Network.

ISO/IEC TR 29181-6:2013 describes the problem statement and requirements for the Future Network in the perspective of media transport. ISO/IEC TR 29181-6:2013 specifies: detailed description of the media transport requirements in the Future Network; identification and definition of services, basic and media services, which will fit the requirements for communications over heterogeneous environments supporting various user preferences, for any kind of media content, either time-dependent or time-independent; requirements and functionalities of Media Aware Network Elements, which are intended to be nodes in the network to provide seamless media experiences to users.

ISO/IEC TR 29181-7:2013 describes the problem statement, requirements and a functional building block for the Future Network (FN) from the perspective of service composition. The goal of is to: analyse and classify problems of the current solutions on the service composition, identify requirements on the service composition for the FN, describe some technical aspects of the service composition for the FN, and propose a functional building block of the service composition including functional components and their reference points among them. ISO/IEC TR 29181-7:2013 also introduces various on-going standardization and research activities related to service composition.

3. FN Relevance with IoT

The FN project not only relates to the work of  this group, but also has some discussions and plans for FN-NOT ( which discusses how a clean slate designed Future Network platform can be used to support the forming of a new Network of Things, or Future Network based Network of Things). As we know, new communication needs may require new network platforms, and newly designed network architectures may also have huge impact on new applications.

SC 6 Future Network project is based on recognition that "explosion of application areas including disruptive technologies like sensor networks and mission-critical applications like disaster recovery demands a more rigid, reliable, and complete networking technology " (6N13295). According to the published technical report "Future Network - Problem Statement and Requirements – Part 1: Overall Aspects", Internet of Things is regarded as part of the service architecture, as the following diagram indicates (ISO/IEC TR 29181-1: 2012, p.26).

In other words, IoT (M2M) is one of the communication services that FN intends to support with new network architectural designs.


4. Significance of SC 6 FN

The significance of SC 6 FN with regard to IoT(M2M) is:

?it brings new perspectives on how the network architecture should be changed or created to provide adequate support to IoT(M2M).

?it encourages technology developers to consider how to take advantage of the clean slate designed FN structure to optimize IoT(M2M) communications.

?other than rely on existing networks or place hopes on modifying current networks, FN provides a third alternative which is to design networks to satisfy the needs of IoT(M2M) communications.
