Hierarchical events for efficient distributed network analysis and surveillance

Abstract

Computer networks are elemental for todays Information Technology (IT) infrastructure. Maintaining operational computer networks is an important and challenging task. For this task the information gathered with means of network analysis and surveillance is the very basis. Detailed network analysis and surveillance is one of the key factors for assuring operational computer networks. However, network analysis and surveillance also poses many challenges like huge performance requirements or distributed application. In this paper we evaluate how event-based data processing and Complex Event Processing (CEP) can be leveraged for addressing these issues by enabling scalable event hierarchies.
