Abstract

There is proposed a mechanism for improving a reliability of a virtual network and resources used. At a virtual network operator level, a request for providing resources for the virtual network is sent towards an infrastructure provider level. The request includes an indication regarding a required availability and reliability level which is to be achieved by the resources of the virtual network. At an infrastructure provider level the request is processed in order to determine the required availability and reliability level, and it is checked whether the required availability and reliability level is achievable for the resources to be provided for the virtual network. A result (confirmation or denial) of the check is sent back to the virtual network operator level.
