Data Center Networking

From small enterprises to large scale cloud providers, most of the existing IT systems and services are strongly dependent on highly scalable and efficient data centers. Yet, these infrastructures still pose significant challenges regarding computing, storage and networking. Concerning the latter, data centers should be designed and deployed in such a way as to offer high and flexible cross-section bandwidth and low- latency, QoS based on the application requirements, high levels of resilience, intelligent resource utilization to reduce energy consumption and improve overall efficiency, agility in provisioning network resources, for example by means of network virtualization and orchestration with computing and storage, and so forth [358], [359], [360]. Not surprisingly, many of these issues remain open due to the complexity and inflexibility of traditional network architectures.
