FNs are recommended to be designed to provide a sustainable competition environment for solving tussles among the range of participants in the

ICT/telecommunictaion ecosystem

Rationale: Many technologies have failed to be deployed, flourish, or be sustainable because of

inadequate or inappropriate decisions of the architect, ...

Sufficient attention therefore needs to be paid to economic and social aspects such as economic incentives in designing and implementing the

requirements, architecture, and protocol of FNs in order to provide a sustainable competition

environment to the various participants

Scope of Y.FNsocioeconomic

Y.3001 lists...Candidate technologiesBut no methods to achieve goals and objectives

„Socio-Economic Aware Design of Future Network Technology“

This Recommendation lists methods to achieve socio-economic design goals and objectives for Future Networks (FNs). When a candidate FN technology is provided, the methods listed provide a structured approach•to anticipate at technology design time the socio-economic impact of the technology taking into account the relevant set of stakeholders, tussles emerging among them, and the range of available choices,•to anticipate either a stable and incentives-compatible or an unstable outcome resulting from deploying the technology,•to identify potential spillover (unwanted) effects from the technology’s primary functionality to another functionality, •and to help design technology for Future Networks that is in-line with the respective socio-economic design goals and objectives.

Tussle Evolution: Bandwidth Sharing

Functionality: bandwidth sharing

ISPs throttle bandwidth of p2p applications by using DPI technology

p2p applicationsconfigured to perform traffic obfuscation

What if ISPs deploy congestion exposure technologies & congestion pricing schemes?

Functionality: VoIP service delivery

Regulator announces fines due to VoIP providers‘ complaints

p2p users get p2p users get disproportionate disproportionate bandwidth sharebandwidth share

p2p users configureapplications to open multiple TCP connections for thesame session

?

ISPs use DPI technology to degrade quality of rival VoIP services
