Dynamic Adaptation of Temporal Event Correlation for QoS Management in Distributed Systems

“…Figure 1 illustrates the characteristics of existing approaches to temporal correlation of events in distributed systems [7,1,5] as they relate to the problem of propagation skew. Event sources generate events (the solid circles) that traverse one or more networks.…”

“…Our work relates to temporal patterns in distributed systems. In particular, none of the systems in [7,1,5] mention propagation skew. Hence, none of these systems provide the architectural or algorithmic support needed to compensate for propagation skew.…”

“…Commonly addressed issues include correlation speed and accuracy [4,11,9] and the expressiveness of correlation patterns. For the latter, there has been particular interest in non-rule based approaches [11], probabilistic correlation [6], and temporal patterns [7,1,5]. Others have recognized the importance of temporal relationships in detecting security problems [12], but have not addressed the specifics of propagation skew.…”
