Abstract

A management device of a transmission system includes a new path information input unit, a statistical information collecting unit that collects statistical information of actual traffic from nodes, and an uninterruptible path designing unit that calculates a delay fluctuation in an entire path with respect to a fluctuation for each section of the path, and designs a path in which the calculated delay fluctuation is smaller than a maximum fluctuation amount according to a buffering amount in the reception node as an uninterruptible path, a path information setting unit that updates path information of the path and stores the updated path information in an existing path information storage unit, and sets a bandwidth permitted in a node constituting the path in the node, and a notification unit that notifies a user of a path that was not designed as the uninterruptible path.
