Main ICN Architectures
Gabriel M. Brito, Pedro B. Velloso, Igor M. Moraes · 2013
This chapter presents some of the main ICN architecture proposals, focusing on how the basic content-oriented concepts are applied. Content-based networking (CBN) architecture is one of the first ICN proposals, heavily based on event-notification publish/subscribe systems. Data-Oriented Network Architecture (DONA) is the first information-centric architecture based on clean-slate concepts for secure and persistent content naming, name-based routing and content distribution in a hierarchical network. Content-Centric Networking (CCN) adopts named content as a first-class citizen, addressing subjects such as high availability and security in a content-oriented fashion, regardless of location. The Publish-Subscribe Internet Routing Paradigm (PSIRP) architecture, in contrast to other ICN proposals, specifies a content-oriented architecture without employing existing connectivity and data transfer technologies. Content-centric inter-network (CONET) architecture proposes a new CONET layer that provides users with network access to remote named-resources rather than to remote hosts. Besides the already presented architectures, there are also other proposals for ICN implementation.
