In this paper, the authors consider bandwidth-intensive services for customers that want Virtual Networks (VN) in a data center environment. In particular, they consider this problem in a temporal context where bandwidth-intensive requests from each VN may arrive randomly at a review point, which may last for certain duration. Thus, at each review point, the data center network provider must optimally allocate resources for the demand requests. For this problem, they present a Mixed-Integer Programming (MIP) problem formulation where any request from a VN customer may be assigned to any Virtual Machine so that network resource availability is optimized.
