– a conceptual model of NoE and its definition;

– problem statements in conventional networking;

– standardization activities of other standards-development organizations;

– requirements for NoE from an IoT perspective;

– technical aspects.

NOTE: Since networking issues are an integral part of IoT and Future Networks, while standards of IoT or Future Networks are under development in other standards-development organizations, this document focuses on networking issues to integrate diverse networking techniques to provide users' service and/or things requirement.

– problems of the current networks for QoS;

– requirements for QoS support in Future Network.

1. analyse and classify problems of the current solutions on the service composition,
2. identify requirements on the service composition for the FN,
3. describe some technical aspects of the service composition for the FN, and
4. 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.

1. detailed description of the media transport requirements in the Future Network;
2. 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;
3. requirements and functionalities of Media Aware Network Elements, which are intended to be nodes in the network to provide seamless media experiences to users.

• 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.

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; and
4. 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.
