A Distributed and Autonomic Virtual Network Mapping Framework

This paper addresses the challenge of assigning virtual networks, through network virtualisation, to the underlying physical network in a distributed and efficient manner. The paper reports on an implementation and evaluation of a distributed and autonomic framework with algorithms responsible for mapping virtual nodes and links to the physical resources. A virtual network (VN) mapping protocol is proposed for exchange of messages between autonomic substrate nodes. Results of the implementation and a performance evaluation of the distributed and autonomic VN mapping using a multi-agent approach are provided.
