Information-centric networking (ICN) TThe network becomes aware of what it delivers, not where Primarily referring to named information objects (IOs), not end-hosts Routing and/or forwarding decisions based on IO names NNew interaction model: publish/subscribe Decoupling of communicating entities No end-to-end communication sessions Network mediates for the delivery of information BBenefits Multicast, Mobility In-network caching and processing (if needed) Reduced application configuration complexity

Publish/subscribe basics  Decoupling data production and consumption in space and time Communicating end-points need not know each other Asynchronous communication possible  Core components Publisher client: produces data Subscriber client: consumes data Broker: stores and forwards data Broker discovery service: indicates broker to publishers and subscribers  Basic interactions Broker discovery Client join Data dissemination Publisher Subscriber Broker Pub/sub middleware Application Join message Data Broker discovery service Broker Subscriber 44 -Can optimize its location -Can perform e.g., filtering/aggregation -Can optimize its location -Can perform e.g., filtering/aggregation
