Summary

Recommendation ITU-T Y.3045 specifies the functional architecture of content delivery in smart ubiquitous networks (SUN) by describing the relevant capabilities, functions, operations and informational flows.

The features of SUN content delivery are name-based content routing, in-network content caching, content delivery optimization, and dynamic content routing adaptive to context information whose principles are content awareness and context awareness as defined in Recommendations ITU-T Y.3044 and ITU‑T Y.3043, respectively.
