For small α more storage at core is
optimum, so the cost reduction
improvement comparing to only edge
caching is bigger (20-30%)

Background
Differences with NFN
(Named Function Networking)

8. 8
NFN processing procedure
 NFN uses a 3-phase strategy, i.e., upstream fetch, separate code and data
fetch, and computation push, to process a functional chaining request

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.
