Abstract

In this paper, we discuss the necessity of new observation and control structures for organic computing systems starting from the basic contradiction between bottom-up behaviour and top-down design. An Observer/Controller architecture serves the purpose to keep emergent behaviour within predefined limits. As an illustration, a framework for reconfigurable protocol stacks is introduced, which contains an agent-based monitoring framework as well as a reconfiguration manager. After describing a TCP/IP protocol stack implementation, based on the framework, similarities between the introduced framework and the Observer/Controller architectural pattern will be pointed out.
