Abstract
One embodiment of the present invention provides a system for forwarding packets with hierarchically structured variable-length identifiers (HSVLIs) in a content-centric network (CCN). During operation, the system receives a packet with an HSVLI and determines, based on the HSVLI, a plurality of ports to which the packet should be forwarded. The plurality of ports include a set of individual port groups, and a respective port group includes one or more individual physical ports. The system derives a forwarding strategy based on the set of individual port groups and the one or more individual physical ports. The forwarding strategy is expressed as a formula in conjunctive normal form that indicates a logical conjunction among the set of port groups and a logical disjunction among the one or more individual physical ports. The system then forwards the packet using the derived forwarding strategy.
