ABSTRACT:
A capacity variable link apparatus including a main signal system and a control signal system is provided. The main signal system includes: an upper layer signal accommodation part; a lower layer path termination part; and a signal switching part for dividing the upper layer signal to lower layer signals in a lower layer path group having a capacity that is determined according to an amount of traffic of the upper layer signal. The control system includes: a traffic amount measuring part for measuring the amount of traffic of the upper layer and for determining whether the capacity of the lower layer path group is to be increased or decreased according to the amount; and a signal switching management part for controlling the signal switching part according to the result of the determination.
