1. Data Center infrastructures, the cornerstones of network virtualization

DC infrastructures are at the heart of the major challenges facing network transformation, with the massive introduction of virtualization techniques for functions historically housed in dedicated switching equipment such as IP routers.

The functional importance of DCs in the provision and operation of a wide variety of services (from Internet access to advanced services, such as those based on the Internet of Things) grows with the complexity of their engineering and operation. The functional richness of certain services relies in particular on the intelligent allocation and combination of resources (network, storage, computing), the configuration of which is indeed complicated: A telemedicine service, for example, which consists in dynamically monitoring a set of biometric data characteristic of an "at-risk" population (in the context of winter flu epidemics,...
