Abstract: Provided is a cloud control server that controls a plurality of cloud servers, the cloud control server including a communication unit configured to transmit, to a mobile device, information about one or more cloud servers from among the plurality of cloud servers, and to receive, from the mobile device, identification information of a cloud server that is selected by a user of the mobile device and is from among the one or more cloud servers; and a controller configured to migrate a virtual machine of the mobile device to the selected cloud server from a cloud server in which the virtual machine of the mobile device is located and that is from among the plurality of cloud servers, wherein the virtual machine of the mobile device executes an application that is output from the mobile device.

Abstract: Provided is a method of delivering, by a device, packets to an application installed on the device the method including: obtaining information regarding a delivery mode determination condition, the information being used to determine a delivery mode of delivering the packets to the application; determining a delivery mode of delivering the packets based on the obtained information regarding the delivery mode determination condition; receiving packets to be delivered to the application through a network interface of the device; and delivering, to the application, the packets to be delivered according to the determined delivery mode.

Abstract: A method of distributing data by a device. The method includes determining a core of a network interface card from multiple cores existing in a server and determining a queue of a network interface card for processing data transmitted from the device. The method further includes determining a sources port of the device for transmitting data to the determined core or the determined queue of the network interface card, by using an inverse-hash function of a hash function that is used by the server. The method also includes transmitting the data to the server, via the determined source port.

Abstract: Provided is an electronic device including a storage configured to store a plurality of operating systems (OSs) and a disk image; an input interface configured to receive a user input for switching focus from a first OS to a second OS; and a processor configured to mount, in response to the user input, to the second OS the disk image having been mounted to the first OS.

Abstract: A method of distributing data includes: determining a core and a queue of a network interface card for processing data transmitted from the device, from among a number of cores in a server; determining a source port of the device for transmitting data to the determined core or the determined queue of the network interface card, by using an inverse-hash function of a hash function that is used by the server; and transmitting the data to the server, via the determined source port.

Abstract: A method of managing data includes controlling to form packed bucket data by packing user data and a pointing map indicating a storage location of the user data; controlling to extract a specific key value that is to be browsed by a user from the packed bucket data; and exchanging the specific key value through a smart interface.

Abstract: Provided are a method and apparatus for programming a buffer cache in a Solid State Disk (SSD) system. The buffer cache programming apparatus in the SSD system may include a buffer cache unit to store pages, a memory unit including a plurality of memory chips, and a control unit to select at least one of the page as a victim page, based on a delay occurring when a page is stored in at least one target memory chip among the plurality of memory chips.
