Abstract:
PURPOSE: A device for providing a distribution cloud service and a method thereof are provided to supply a distribution cloud computing service in which availability is high, thereby inspecting the integrity of information. CONSTITUTION: A control unit(730) converts first information into second information, and stores the same in cloud servers. The control unit finds the first information using the second information received from a part of cloud servers, and provides the first information to a user. The control unit inspects the integrity of the first information using the second information. A transmission unit(710) transmits the second information to the cloud servers. A receiving unit(720) receives the second information from the part of cloud servers. [Reference numerals] (710) Transmission unit; (720) Receiving unit; (730) Control unit; (740) Providing unit
Abstract:
PURPOSE: An equal bandwidth allocation based packet scheduling method and apparatus thereof are provided to effectively control the traffic congestion of a network by determining a scheduling time for each packet. CONSTITUTION: A packet scheduling apparatus calculates the predicted arrival time of a k+1 packet according to each flow(110). When the k+1 packet arrives, the packet scheduling apparatus compares the predicted arrival time of the k+1 packet with the actual arrival time of the k+1 packet(120). The packet scheduling apparatus schedules the k+1 packet of each flow according to comparison results(130).

Abstract:
Disclosed is a method of handing a fault in a software defined networking (SDN) network. First, information about an indirect port switched when a fault occurs in a flow table is set. When a fault is sensed, after information about an indirect port corresponding to the port in which the fault has occurred is obtained, the port in which the fault has occurred is switched into the obtained indirect port based on the obtained indirect port information. Thus, when a fault occurs, the fault can be rapidly handled so that the continuity of traffic transmission can be guaranteed.
Abstract:
PURPOSE: A cell scheduling method guaranteeing the priority of a switch having an input queue is provided to extend the range of application targets. CONSTITUTION: Information about cells with high priority is provided in advance. A generalized diagonal line, which is composed of processing elements connected along a column and a row, is generated. A transfer matrix is generated and updated by considering the priority provided in advance for the processing elements forming the generated diagonal line. Cells in the transfer matrix are transmitted.
