ABSTRACT:
A network of nodes interconnected by links has content filtering specified at certain nodes, and routing of packet connections through the network is generated based on the specified content-filtering nodes. The network is specified via a content-filtering node placement method and a network-capacity maximization method so as to apply content filtering to packets for substantially all traffic (packet streams) carried by the network.
