Knowledge Dissemination for Autonomic Network
Autonomic computing is a new paradigm inspired by the biological world. It allows networks to self-organize control decisions. To ensure an efficient self-organization, an autonomic network must define a new distributed and decentralized plane containing all the network knowledge, called a knowledge plane. In this paper, the authors propose new knowledge dissemination mechanisms in order to maintain this knowledge plane. The developed approach is composed of three modules to address scalability and interoperability issues: cluster the network nodes and elect a leader for each cluster to contain the knowledge, use an overlay network to disseminate knowledge between leaders for interoperability concerns and, disseminate only useful knowledge to nodes in each cluster to reduce the amount of knowledge to be distributed.
