ABSTRACT:
A relay device includes a plurality of physical ports physically connected to a plurality of other relay devices on a network to form physical links; a setting unit for setting one or more logical links for each of the physical links; an evaluation unit for automatically adding an evaluated value based on communication characteristics of the logical link when a control packet is received from a first relay device through the logical link or the control packet is transferred to a second relay device through the logical link; and a unit for selecting, when there are a plurality of routes that merge at the relay device, one of the routes based on evaluated values accumulated by the other relay devices.
