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.

Abstract: A network tap for enabling attached devices, such as an intrusion detection system, to transmit information into a communication line of the network without disrupting the network traffic on the communication line. When the attached device is an intrusion detection device, the network tap is connected to a firewall. An Ethernet switch or field programmable gate array (FPGA) is incorporated in the network tap to coordinate the transmission of device data to avoid data collisions with data transmissions already existing in the communication line. The network tap may be operated in various modes to accommodate different capabilities of attached devices. In addition, the network tap has various port configurations to allow a user to connect various attached devices through a single cable or dual cables.
