Computing systems have been focused on performance improvements, driven by the
demand of user applications in past few decades, particularly from 1990 to 2010. However …

Multiple distributed controllers have been used in software-defined networks (SDNs) to
improve scalability and reliability, where each controller manages one static partition of the …

Data center network architectures that can reduce the cost and complexity of data center
networks. The data center network architectures can employ optical network topologies and …

This article proposes an approach that enables a cloud infrastructure MANO entity, in a
virtualized infrastructure (eg, a data center) that hosts virtualized networks and services, to …

Due to energy crisis of the last years, energy waste and sustainability have been brought
both into public attention, and under industry and scientific scrutiny. Thus, obtaining high …

We study the problem of optimising the provisioning of collections of virtual machines (VMs)
having different placement constraints (eg, security and anti-collocation) and characteristics …

Abstract Systems and methods of affinity modeling in data center networks that allow
bandwidth to be efficiently allocated with the data center networks, while reducing the …

Container technology has become a new trend in both the software industry and cloud
computing. Containers support the fast development of web applications and they have the …

Data center networks that employ optical network topologies and optical nodes to efficiently
allocate bandwidth within the data center networks, while reducing the physical intercon …

A connectivity device permits simplified connections for realizing complex networking
topologies using lower cost components. The device can be optically passive, or can have …
