Abstract:
Provided are a method and an apparatus for controlling congestion based on a generation Z (Gen-Z) interface. When a first device receives, from a second device, a second packet that is a response to a first packet transmitted to the second device, and the second packet indicates that a congestion situation occurs, the first device records priority information of a packet in a predetermined field for congestion control among fields according to the Gen-Z interface. Then, the first device transmits a third packet including priority information to the second device.

A service architecture for virtual desktop service according to the present invention includes a connection broker configured to perform authentication, manage virtual machines, and perform a server monitoring and protocol coordination function, a resource pool configured to manage software resources that are delivered to a specific virtual machine in a streaming form on a specific time in order to provide on-demand virtual desktop service and are executed on the specific virtual machine and to provide provision information about the managed software resources in response to a request from the connection broker, and a virtual machine infrastructure configured to support hardware resources, generate virtual machines in which the software of a user terminal is executed, and provide the generated virtual machine as virtual desktops.
Abstract:
Disclosed herein are an apparatus and method for providing a cloud brokerage service based on multiple clouds. The method includes receiving, by a cloud service broker, a request for a cloud service from a cloud service client, the cloud service broker being connected with the multiple cloud-computing systems; providing, by the cloud service broker, a cloud service brokerage based on cloud services of the cloud-computing systems, the cloud service brokerage enabling the cloud service complying with the request to be provided to the cloud service client; transmitting, by the cloud service broker, a control request for the cloud service to one or more cloud-computing systems of the multiple cloud-computing systems; and controlling, by the cloud service broker, a status of the cloud service after the cloud service broker receives an acknowledgment for the control request from the one or more cloud-computing systems.
Abstract:
Disclosed herein are an apparatus and method for providing a cloud brokerage service based on multiple clouds. The method includes receiving, by a cloud service broker, a request for a cloud service from a cloud service client, the cloud service broker being connected with the multiple cloud-computing systems; generating, by the cloud service broker, the cloud service complying with the request based on one or more services registered in a service catalogue of the cloud service broker; newly registering, by the cloud service broker, the generated cloud service in the service catalogue; and providing, by the cloud service broker, the newly registered cloud service to the cloud service client.
Abstract:
Disclosed herein are a method and apparatus for virtual desktop service. The apparatus includes a connection manager configured to perform an assignment task of assigning a virtual machine to a user terminal using virtual desktop service, a resource pool configured to allocate software resources to a virtual desktop, wherein the software resources include an OS, applications, and user profiles, and a virtual machine infrastructure configured to support hardware resources including a CPU and a memory, wherein the connection manager is configured to perform a coordination task of coordinating a delivery protocol used between the user terminal and servers that provide the virtual desktop service, wherein the resource pool has a management function, wherein the management function is based on usage pattern information about a user's average usage of resources, and wherein the management function uses a physical distance on network from the user terminal to a server.
