Abstract
A patch controller, when removal of a to-be-deleted node on a virtual path is detected, extracts a node immediately before deletion located adjacently to and on an upstream side of the to-be-deleted node on the virtual path and a node immediately after deletion located adjacently to and on a downstream side of the to-be-deleted node, forms a bypass path for discharging a queued packet being processed by the to-be-deleted node to the node immediately after deletion, and a changed path excluding the to-be-deleted node from the virtual path, by making a connection so as to cause a transfer packet from the node immediately before deletion to flow to the node immediately after deletion, and prioritizes processing of discharging the queued packet to the node immediately after deletion on the bypass path over processing of transferring the transfer packet to the node immediately after deletion on the changed path.
