Abstract

Information Filters play an important role in processing streams of events, both for filtering as well as routing events based on their content. Stateful information filters like AGILE [15], Cayuga [13] and SASE [24] have gained a significant amount of attention recently. Such filters not only consider the data of a single event, but also additional state such as a sequence of previous events or a context state. Applications for Wireless Sensors and RFID data are particularly prominent examples for the need for stateful information filtering, with use cases like event correlation or sensor data affecting the routing of other events. While quality of service has been researched fairly thoroughly for networking systems and general data stream management systems, no comprehensive work exists for information filters. The goal of this work is to present QoS criteria for stateful information filters and to examine how QoS control methods established in other areas can be applied to information filters.
