There is little resource management and Quality of Service (QoS) guarantee in the "best-effort" model underlying existing information systems, leaving information systems vulnerable to exploits and denial-of-service attacks. To overcome these problems, an engineering approach to QoS-centric stateful resource management in information systems is presented in this paper. System engineering principles are first used to identify various scales and levels of resources in information systems. QoS attributes of resources are then discussed. We also introduce the topological and algebraic structures of propagating QoS attributes across levels and scales of various resources for service contracting and admission control. We use a control-theoretic structure to specify QoS-guarantee functions for managing individual resources, including functions of admission control, scheduling & control, QoS confonnance monitoring, and state probing and testing, along with scheduling techniques and statistical process control (SPC) techniques to support these functions.
