<p><P>PROBLEM TO BE SOLVED: To improve quality by avoiding convergence, a delay, and a packet loss by dispersing transmit data when the data are transmitted and received through a best-effort type network. <P>SOLUTION: Provided is a path controller 14 internally having a path state managing means 15 of gathering states of paths if a server as a data transmission source is connected to the Internet in a multi-home environment when distributing servers 11 and 12 and a client 30 communicate with each other through the Internet, a path selecting means 16 of selecting a plurality of optimum paths out of the plurality of paths, and a traffic distributing means 17 of performing the path dispersion of transmission traffic. As a method for selecting the plurality of paths, available is a method of selecting the plurality of paths according to a set policy on the basis of a parameter featuring respective paths during management by the path state managing means 15. As a method for distributing traffic, available is a method of performing the distribution by sending out corresponding interface traffic from a destination network selected by, for example, the path selecting means 16 to a corresponding interface. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
