Abstract:
1. A method of message filtering in a publish/subscribe system, comprising the steps of: arranging a plurality of topics in a semantic hierarchical tree comprising first nodes that represent semantic information of the plurality of topics; responsively to predetermined optimization requirements rearranging the semantic hierarchical tree to form a virtual topic tree having branches by adding second nodes therein to thereby regroup the plurality of topics; establishing first and second nodal associations between a stream of messages and respective first nodes and second nodes of the virtual topic tree, respectively, according to conformance of the messages with the branches of the virtual topic tree; in a computing apparatus segmenting the stream of messages into bundles of messages having at least one common first and second nodal association, the bundles further comprising flow labels and node labels that specify the at least one common first and second nodal association, respectively; and transmitting the bundles to a receiver adapted for filtering of the messages therein responsively to the flow labels and the node labels.
