Network virtualization has gained visibility by enabling the development of new functionalities and applications for the internet. With virtualization, a logical view of the hardware is created so that multiple virtual networks can coexist on the same physical network substrate. The virtual network embedding problem belongs to the NP-hard class not allowing the use of exact approaches. In this work, the application of a fast heuristic approach in a multidomain, decentralized and online environment is proposed, through an orchestrator's control. A comparative study regarding the implementation of three different orchestration models is presented: total knowledge, partial and without knowledge of the internal physical network infrastructure of the domains. Experimental results show the performance of the orchestrator along with the heuristic, reporting energy consumption, profit generation and message exchange metrics for the different approaches.
