Active networks are a communication paradigm that allows packets flowing through a communication network to dynamically modify the operation of the network.

Abstract
As we move towards service-oriented complex infrastructures, what is needed, security, robustness, and intelligence distributed within the network. Modern systems are too complicated to be centrally administered; therefore, the need for approaches that provide autonomic characteristics and are able to be self sustained is evident. We present here one approach towards this goal, i.e., how we can build dynamic infrastructures based on mobile agents (MA) and active networks (AN). Both concepts share common ground at the architectural level, which makes it interesting to use a mix of them to provide a more sophisticated framework for building dynamic systems. We argue that by using this combination, more autonomous systems can be built that can effectively possess at least at some level of self-* features, such as self-management, self-healing, etc., which, in conjunction with cooperation capabilities, will lead to the deployment of dynamic infrastructures that autonomously identify and adapt to external/internal events. As an example, the implementation of an autonomous network-based security service is analyzed, which proves that denial of service attacks can be managed by the network itself intelligently and in an autonomic fashion.
