Mobility-Aware Distributed Embedding (MADE) of virtual networks

Network virtualisation has been recently presented as a mean to overcome the saturation of the current Internet by sharing the same infrastructure by different network operators. The efficient embedding of Virtual Networks in the physical substrate represents one of the main challenges associated to this technique, since it is necessary to set up a coordinated procedure to provide the requested set of resources in the most beneficial way. We propose a novel embedding protocol, designed in a distributed manner, and especially focused on solving the problems derived from the dynamicity of the nodes in mobile environments. Our Mobility-Aware Distributed Embedding (MADE) protocol applies the well known Path Splitting and Migration techniques in order to optimize the use of the physical resources. A simulation-based study lets us show the efficiency of our protocol and the good results in terms of acceptance and finalization of Virtual Networks. ¹
