In-network aggregation and distribution of conditional internet of things data subscription in information-centric networking

摘要

The disclosure relates to technology for routing data in an information centric network (ICN). A first interest message received at a router in the ICN is identified as including a first subscription request and a first notification condition from a first subscriber. The method then determines whether the first notification condition has an overlap with a second notification condition included in a second subscription request stored in a forwarding information base (FIB) of the router, where the second subscription request is included in a second interest message that was received at the router and forwarded by the router towards a producer of the data. The first notification condition may then be aggregated with the second notification condition by changing the first notification condition in the first subscription message based on the second notification condition.
