COMMUNICATION CONTROLLER, COMMUNICATION CONTROL METHOD, AND COMMUNICATION CONTROL PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a communication controller etc. capable of implementing required communication performance by preventing, without increasing a cost, reduction in communication performance caused by increase in a software processing load.SOLUTION: A communication controller comprises: a plurality of virtual switches for accommodating communication paths from respective virtual machines grouped for communication quality so that each virtual switch accommodates communication paths of its corresponding group; network interfaces each of which is connected to a virtual switch and includes a plurality of virtual interfaces for operating in a band permitted by the interface; and management means for performing setting so that communication quality for each group is satisfied in at least either of a virtual switch's connection interface to a virtual machine and connection interface to a virtual interface.SELECTED DRAWING: Figure 1
