Abstract
In this paper, we show how ad-hoc queries can be made in real time on network traffic data using a data stream model. We define a rich class of ordering properties and use them to label the attributes of a stream. The attribute ordering properties can be used to optimize data stream queries, enabling the efficient evaluation of complex ad-hoc queries. The rich set of ordering properties allows the output of many operators on data streams to also be labeled with ordering properties, allowing the composability of data stream queries. We show how an SQL-like language can express many network analysis query, and be translated into data stream operators. We use the data stream model described in this paper as the query processing architecture for Gigascope, a fast and flexible network
