Research and development of autonomics have come a long way, and we are - lighted to present the proceedings of the 4th IEEE International Workshop on Modeling Autonomic Communications Environments (MACE 2009). As in the last three years, this workshop was held as part of Manweek, the International Week on Management of Networks and Services, which took place in the cult- ally rich city of Venice in Italy. Manweek is now an umbrella of ?ve workshops and conferences focusing on di?erent aspects of network and service mana- ment, including MACE, distributed operations and management (DSOM), - basedmanagement(IPOM),towardsmultimediaandmobilenetworks(MMNS), and virtualization and middleware for next generation networks (NGNM). F- ther information of Manweek and the individual workshops and conferences can be found athttp://www.manweek.org. MACE started as an experiment, in 2006, and created a small community that now ?nds itself attracted back each year by a feeling of excitement and anticipation to share new advances and development. Certainly, MACE is not as shiny or practiced as other well-known conferences and workshops, but we consider this a feature of the workshop itself. New ideas, a little rough around theedges(andsometimesmorethanalittle),oftenquiteun?nished,popoutand provoke extensive discussion. Science needs this kind of exploratory adventure, and we have been strongly motivated to continue preserving this atmosphere of exploration and discussion in this year’s technical program.

This book presents a comprehensive reference of state-of-the-art e?orts and early results in the area of autonomic networking and communication. The essence of autonomic networking, and thus autonomic communication, is to enable the - tonomic component, device or system to govern the set of services and resources delivered at any given time while protecting context-sensitive business goals. An additionalchallengeistoprovideself-governanceinthefaceofchanginguserneeds, environmental conditions, and business objectives. In other words, an autonomic network understands relevant contextual data and changes to those data, and adapts the services and resources it provides in accordance with business-driven policies that protect user and business interests. Autonomic computing is often described as self-CHOP (self-con?guration, -healing, -optimisation, and -protection). Autonomic networking instead focuses on self-knowledge,which is the foundation to build self-governance.Note that self- CHOP functionality is still provided, but the emphasis of autonomic networking is on the foundation to realise self-CHOP, not in the di?erent self-* technologies and bene?ts.
