Abstract
The same label value is assigned to all links configuring a connection in a network where an LSP (Label switched Path) is identified based on a label. Even when any one of nodes included in the connection is shortcut due to a change of route of the connection, a neighboring node to this shortcut node in the transmitting direction can receive, from a neighboring node to the shortcut node in the receiving direction, a packet having the same label value as a label value received from the LSR.
