Apparatus and method for managing flow in server virtualization environment, and method for applying QOS

摘要

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.

1. An apparatus for managing a flow in a server virtualization environment, the apparatus comprising:
a receiver which is configured to: receive a flow generated by a virtual machine implemented in a server; and a processor which is configured to: analyze the flow generated by the virtual machine 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 via a flow processing unit; generate in a case in which the flow is the new flow, the 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 via a QoS management unit; and manage the virtual machine and the prestored virtual machine information via a virtual machine management unit, wherein the virtual machine management unit transmits an instruction signal to the server in which the virtual machine is implemented, and receives, by the apparatus, a result of processing the instruction signal and changed virtual machine information from the server.
