An Observer/Controller Architecture for Adaptive Reconfigurable Stacks

摘要

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.
