Network virtualization represents one of the most promising approach to unlock innovation in current network technologies. This paper presents AiroLAB, a wireless network virtualization solution aimed at providing Wireless Internet Service Providers with an effective tool to support experimental testing of novel network - level solutions on production networks. In the paper, the design choices which lie at the basis of AiroLAB are presented and discussed together with a prototype implementation. The outcomes of measurement activities performed on a small-scale testbed demonstrate the strength of the proposed framework in preserving guaranteed performance for production traffic while allowing several experimental instances to run on a network in operation.
