7.4 Social and economic awareness

FNs are recommended to consider social and economic issues to reduce barriers to entry of the various actors
involved in the network ecosystem. FNs are recommended to also consider the need to reduce their lifecycle
costs in order for them to be deployable and sustainable. These factors will help to universalize the services,
and allow appropriate competition and an appropriate return for all actors.

8 Design goals
Design goals are high-level capabilities and characteristics that are recommended to be supported by FNs.
FNs are recommended to support the following design goals in order to realize the objectives mentioned in
clause 7. It should be noted that some of these design goals may be extremely difficult to support in a
particular FN, and that each design goal will not be implemented in all FNs. Whether the support of each of
these design goals in a specific FN will be required, recommended, or optional, is a topic for further study.
Figure 1 below shows the relationships between the four objectives described in clause 7 and the twelve
design goals described in this clause. It should be noted that some design goals, such as network
management, mobility, identification, and reliability and security, may relate to multiple objectives. Figure 1
shows only the relationships between a design goal and its most relevant objective.

8.1 Service diversity

FNs are recommended to support diversified services accommodating a wide variety of traffic characteristics
and behaviours. FNs are recommended to support a huge number and wide variety of communication
objects, such as sensors and terminal devices.
Rationale: In the future, services will become diversified with the appearance of various new services and
applications that have quite different traffic characteristics (such as bandwidth and latency) and traffic
behaviours (such as security, reliability, and mobility). This requires FNs to support services that existing
networks do not handle in an efficient manner. For example, FNs will have to support services that require
only occasional transmission of a few bytes of data, services that require bandwidth in order of Gbit/s,
Terabit/s, and beyond, or services that require end-to-end delay that is close to the speed-of-light delay, or
services that allow intermittent data transmission and result in very large delay.
