Adaptive Management for Networked Systems
A. Prieto · 2006
As networked systems grow in size and dynamicity, management systems must become adaptive to changing networking conditions. The focus of the work presented in this thesis is on developing engineering principles for adaptive management systems. We investigate three problems in the context of adaptive management for networked systems. First, we address the control of the performance of an SMS system. We present a design for policy-based performance management of such systems. The design takes as input the operator's performance goals, which are expressed as policies that can be adjusted at run-time. The system attempts to achieve the given goals by periodically solving an optimization problem that takes as input the policies and traffic statistics and computes a new configuration. We have evaluated the design through extensive simulations in various scenarios and compared it with an ideal system. A prototype has been developed on a commercial SMS platform, which proves the validity of our design. Second, we address the problem of decentralized continuous monitoring of network
