Research on virtual machine dynamic migration strategy based on Xen Zhang Pu Liaoning University in this paper, a dynamic migration strategy based on Xen virtual machine is proposed for the Xen platform environment, combining the actual application scenario and the Xen bottom migration. The specific work is as follows: first, in order to carry out virtual machine migration in the cloud computing environment, Xen Migration uses a comparison between passing the page bitmap and skipping the page bitmap to determine whether the memory page is retransmission. For page bitmap comparison brings multiple retransmission increase network transmission overhead, put forward the memory optimization algorithm based on AR model, according to the memory page of the record all modified ...

The era of cloud computing, which is widely touted as a success story for international companies such as Google, Amazon, Microsoft and Cisco, is at hand. But cloud computing has not yet formed a real scale commercial application. 2010, one of the most power words in the IT field is not "cloud computing". Newspapers and periodicals published a large number of articles to report cloud computing, experts, academics, entrepreneurs, officials also relish, many provinces and cities to the cloud industry and cloud applications into the "Twelve-Five" plan. October 18, 2010, the National Development and Reform Commission and the Ministry of Industry and Information Technology jointly issued the "about doing a good job of cloud computing services innovation and development ..."

"Ethernet is the backbone of cloud computing. "Is this statement too exaggerated?" Really。 Any data center, cloud computing or anything like that depends on the Ethernet network that allows servers, storage systems, and other devices to transmit to and from each other. No network, no data center. Today, the IT department prepares to deploy an internal cloud environment that can significantly assess how the network infrastructure will affect cloud computing capabilities to meet service level agreements (SLAs). Common terminology to describe cloud computing capabilities, such as agility, flexibility, and scalability, are absolutely applicable to the underlying network and related terms. Considering this point ...

With Intel's drive, IT system communications bandwidth and computing power follow Molfa to record highs, maintaining a doubling of growth rates every 12-18 months.
