KCN: Knowledge Centric Networking.

The advent of multi-domain and multi-requirement digital services requires an underlying network ecosystem able to understand service-specific contexts. In this work, we propose Knowledge Centric Networking (KCN), a paradigm in which knowledge is positioned at the center of the networking landscape. KCN enables approaches by which in-network knowledge generation and distribution can be used to support advanced network control intelligence that is essential to handle complexity and uncertainty in these emerging digital services. In this paper, we introduce the principles of KCN and present an architecture for its realization that enables in-network knowledge creation, distribution, storage and processing, both within a single domain/player and across potentially heterogeneous domains/players.
