Smart architecture in SSCs Requirements

and architectural
Smart architecture in SSCs requires ensuring interoperability,
scalability, flexibility, fault tolerance, availability, manageability, design for SSCs
resilience, and vendor independence. These factors are essential
when putting in place or integrating ICTs into a city›s existing Examples of ITU standards and
