METHOD FOR STORING BOOLEAN FUNCTIONS TO ENABLE EVALUATION, MODIFICATION, REUSE, AND DELIVERY OVER A NETWORK

Data structures for storing subscription predicates for transmission in a publish-subscribe network. Subscriptions include Boolean-valued predicates defining content desired by a subscriber. An agent application converts the predicates into a suitable form for storing them in a common data structure. The predicates are used to generate filters to encapsulate the subscriptions, and the filters are specified in the data structure in addition to the Boolean relationships of the predicates. Routers in a network core use the data structure for content-based routing, which involves applying attributes in received packets to the filters.
