An apparatus for virtual switching includes a queue memory configured to store at least one queue; a data memory configured to store data; a mapper configured to classify the data into flows and store a point of the data in a queue mapped with the flows; a plurality of virtual machines configured to perform a process based on the data; and a virtual switch configured to extract the data from the data memory by referring to the point stored in the queue and transfer the data to the virtual machine, wherein the virtual switch transfers the data corresponding to a single queue to a single virtual machine.

Apparatus and method for virtual switching

An apparatus for parallel processing according to an example may include a queue memory configured to store one or more queues, a data memory configured to store data, a mapper configured to classify the data into flows and store a pointer of the data in a queue mapped with the flow; a plurality of processors configured to perform a process based on the data; and a distributor configured to extract the data from the data memory by referring to the pointer stored in the queue and transmit the data to the processor, wherein the distributor transmits data corresponding to a single queue to a single processor.

Apparatus and method for parallel processing

An apparatus and method for managing a flow in a server virtualization environment, and a method of applying a QoS policy, the method including a flow processing unit configured to analyze a flow generated by a virtual machine (VM) to extract flow information, determine whether the flow is a new flow by comparing the extracted flow information with preset flow information, and apply a corresponding Quality of Service (QoS) policy to the flow, and a QoS management unit configured to, in a case in which the flow is a new flow, generate a QoS policy for the analyzed flow based on the extracted flow information and prestored virtual machine information, and transmit the generated QoS policy to the flow processing unit.
