The document discusses a functional chaining system developed by Fujitsu Laboratories, focusing on optimizing routing, in-network caching, and whole-chain security. It highlights processes like 3-phase strategy for function request handling in named function networking (NFN) and compares it to traditional methods, emphasizing improvements in efficiency and cost reduction. Key differences are described regarding naming conventions and data processing procedures in NFN.

- 9. 9 NFN NDN Router NDN Router NDN Router NDN Router NFN-capable Router Interest (|data|h|g) Interest (|data|h|g) Interest (data) Interest(g) Assume we have a chain of function applications f(g(h(data))): NFN encodes it as |data|h|g|f Phase 2 of NFN (separate code and data fetch): An Interest is firstly forwarded to an NFN-capable router, which can divide the Interest to fetch multiple data and functions (codes). After that, data can be processed at the NFN-capable router and returned back to the consumer. Data Function h Function g Data (data) Data(g) Data (|data|h|g)Data (|data|h|g)
