Cloud Radio Access Networks (Cloud-RANs) have recently emerged as a promising architecture to meet the increasing demands and expectations of future wireless networks. Such an can enable dynamic flexible network operations address significant challenges, such higher mobile traffic volumes operation costs. However, implementation compute-intensive signal processing Network Functions (NFs) on Gen...

Aiming at data center virtual machines Migration, allocating resource dynamically in order to reduce energy is a significant problem in cloud. This energy doesn’t cause only the decrease of cloud provider’s profit but also emit a large amount of carbon dioxide. This paper studies the resource allocation and live migration of Virtual Machines (VMs). It proposes a Double Threshold Migration (DTM)...

Glial cells of both vertebrate and invertebrate organisms must migrate to final target regions in order to ensheath and support associated neurons. While recent progress has been made to describe the live migration of glial cells in the developing pupal wing (1), studies of Drosophila glial cell migration have typically involved the examination of fixed tissue. Live microscopic analysis of moti...

Cluster platforms, deployed in data centers worldwide, are the backbone of the popular cloud computing services. For scalability, manageability and resource utilization, one physical machine in the cloud platform can be virtualized into a bundle of virtual machines (VMs). Each VM works as an independent node. To solve a time consuming task, several VMs are grouped as a virtual cluster and colla...

A complex challenge in mobile computing is to allow the user to migrate her highly customised environment while moving to a different location and to continue work without interruption. I motivate why this is a highly desirable capability and conduct a survey of the current approaches towards this goal and explain their limitations. I then propose a new architecture to support user mobility by ...

Live migration of virtual machines (VMs) is key feature of virtualization that is extensively leveraged in IaaS cloud environments: it is the basic building block of several important features, such as load balancing, pro-active fault tolerance, power management, online maintenance, etc. While most live migration efforts concentrate on how to transfer the memory from source to destination durin...

Live virtual migration is a way for achieving system load balancing in a cloud environment by transferring an active VM from one physical host to another. This way has been developed to decrease the downtime for migrating overloaded VMs, but it still consumes timeand cost, and a huge amount of memory is involved in this migration process. To overcome these drawbacks, we propose a Load Balancing...

Executive Summary This paper provides a deep look at the performance implications of the live storage migration of a VM running a large SQL Server database workload. Performance of the workload when migrating different components of the database (data, index, and log) was measured and compared against the steady state performance (when there was no migration). Experiments discussed in this pape...
