Self provisioning framework for virtualized network functions

The Dynamic nature of the future software networks built upon SDN, NFV and Cloud principles calls for continuous provisioning to ensure service availability and continuity. In this paper, we present and demonstrate a Self-provisioning framework for efficient deployment, configuration and chaining virtual network function in real cloud infrastructure. The Self Provisioning framework realizes dynamic and agile adjustment of the resource allocation to the customer requests with 1) smart triggering of the right optimization algorithm and 2) dynamic workflow establishment including the configuration of the framework modules. The framework relies on the autonomic control loop design, a.k.a. MAPE-K (Monitor, Analyse, Plan, Execute-Knowledge).
