The mobile agent paradigm can be employed effectively for the decentralized management of complex networks. Nevertheless, legacy management protocols such as SNMP need to be supported for reasons of migration and efficiency. We show how the integration of the two paradigms leads to a flexibly adjustable decentralized management architecture. NetDoctor is a(More)
This chapter aims to address some of the fundamental issues that are often encountered in optimization problems, making them difficult to solve. We explain why these issues make optimization problems hard to solve and present some possible countermeasures for dealing with them. By doing this, we hope to help both practitioners and fellow researchers to(More)
Many examples for emergent behaviors may be observed in self-organizing physical and biological systems which prove to be robust, stable, and adaptable. Such behaviors are often based on very simple mechanisms and rules, but artificially creating them is a challenging task which does not comply with traditional software engineering. In this article , we(More)
This article provides an overall view of available techniques for integrating Petri-nets and object-oriented concepts. In order to outline specific characteristics, all identified techniques will be grouped into three categories. For each of these categories, one representative technique will be selected as well as demonstrated using the example of a simple(More)
Genetic programming is known to provide good solutions for many problems like the evolution of network protocols and distributed algorithms. In such cases it is most likely a hardwired module of a design framework that assists the engineer to optimize specific aspects of the system to be developed. It provides its results in a fixed format through an(More)
