Abstract

The goal of this paper is to show the benefits of using reflective techniques and meta-programming in the context of active networks, i.e. networks where packets may contain code which programs the network's behavior. By having separate base-levels and meta-levels it is possible to better structure services built with mobile code. In this paper we propose an active network node architecture supporting such a meta-level and we describe a prototype allowing to integrate meta-code at load-time. Structural reflection is used to modify the behavior of the active service when installed in the node.
