Abstract
In a network management system performing a fault management process in a hierarchical network, an upper layer fault manager performs a fault management of an upper layer of a hierarchical network, a lower layer fault manager performs a fault management of a lower layer of the network, an inter-layer node connecting information storage portion manages connecting information between packet switching nodes composing the upper layer and link offering nodes composing the lower layer, and an inter-layer fault notifying portion notifies the upper layer fault manager, upon receiving a notification of a link fault which has occurred on a link between the link offering nodes from the lower layer fault manager, that the packet switching nodes affected by the fault are faulted, based on the connecting information.
