Basic Abstractions for an Autonomic Network Architecture

The ANA (Autonomic Network Architecture) project aims at providing a framework to flexibly host, interconnect, and federate multiple heterogeneous networks in an autonomic way, i.e. without requiring active human intervention. The guiding design principle is to strive for a maximum degree of flexibility at all levels of the architecture in order to inherently support heterogeneity and evolution. This paper describes the core abstractions and concepts of ANA (as defined during the first year of the project) and introduces their basic operation and interaction. While not autonomic themselves, the core architectural principles of ANA will enable autonomicity by not imposing a "one-size-fits-all" approach where protocols and paradigms are fixed by the architecture. We indeed argue that only the capacity of the network to be polyfunctional and fully adaptable will justify the label \´ autonomic\´. A prototype ofANA is currently being developed and will be released in 2008: the goal is to demonstrate the feasibility of autonomic networking within the 4 years of the project.
