Abstract
A method and apparatus provide for content-based routing of packets in a publish-subscribe network. A packet is received via the network. A map specifying computed filter coverage in an attribute space is accessed. Content of the packet is inspected for a routing decision for the packet. The map is used for the routing decision for the packet. The packet is routed based upon the inspected content of the packet and the map. A router for content-based routing of packets in a publish-subscribe network, comprising modules for performing this method is provided. A network including a plurality of such routers is provided. A computer-readable medium including instructions for performing this method is provided.
