Terms of References • FG Objective
The objective of the Focus Group is to collect and document information and concepts that would be helpful for developing Recommendations to support cloud computing services/applications from a telecommunication/ICT perspective.
• Specific tasks and deliverables- Benefits of cloud computing from telecommunication/ICT perspectives- Gap analysis of ITU-T standards for telecommunication/ICT to support cloud
computing- Collect and summarize vision and value propositions of cloud computing with a
focus on telecommunication/ICT aspects- Leverage expertise within the ITU-T in building telecom networks to take
advantage of cloud concepts and capabilities- Terminology and taxonomy and to develop new definition when necessary- Analysis of telecommunication/ICT networking requirements functions and
capabilities to support cloud computing services/applications (for both fixed and mobile)- Use cases of services and reference models for telecommunication/ICT to support
cloud computing- Roadmap to guide further developments of relevant ITU-T Recommendations.
