This article discusses the technologies for realizing highly efficient data migration and
backup for big data applications in elastic optical inter-data-center (inter-DC) networks. We …

In an optical inter-datacenter (inter-DC) network, for preventing data loss, a cloud system
usually leverages multiple DCs for obtaining sufficient data redundancy. In order to improve …

With its agile spectrum management in the optical layer, the flexible-grid elastic optical
network can become a promising physical infrastructure to efficiently support the highly …

With the boom of Internet of Things (IoT), an increasing amount of data from IoT applications
is moved to geo-distributed data centers (DCs) for data analysis. Massive compute …

Due to widespread applications and rapid development of cloud computing and Internet
services, hyperscale data centers have experienced an unprecedented demand for …

Survivability against disasters—both natural and deliberate attacks, and spanning large
geographical areas—is becoming a major challenge in communication networks. Cloud …

Disaggregated data centers (DCs) can offer high flexibility for resource allocation; hence,
their resource utilization can be significantly improved. However, communications between …
