摘要： A noise suppression method is used in an optical transmission system which includes node equipments transmitting a WDM optical signal. First node equipment drops a first optical signal from the WDM optical signal. The method includes: transmitting a failure signal that specifies the first optical signal from second node equipment to the first node equipment via a first route when the second node equipment arranged on the first route for transmitting the first optical signal to the first node equipment has detected a failure of the first optical signal; transmitting a shutoff signal that specifies the first optical signal from the first node equipment toward the second node equipment via the first route; and shutting off an optical output of a wavelength corresponding to the first optical signal in third node equipment that has relayed the failure signal and has received the shutoff signal.

摘要： In a transmission network system in which a path is set between a transmission node and a receiving node and which transmits a transmission signal between the nodes, crossconnect settings of the nodes are enabled while personal settings are minimized.A transmission node has a first path-setting-receiving section; transmission-path-setting change sections; and change insertion sections which report information about a change in path setting received by said path-setting-receiving section by inserting the information into a transmission signal to be transmitted from the node to a receiving node. The receiving node has a second path-setting-receiving section and receiving-path-setting change sections for changing path settings of the node on the basis of the information about a change in path setting.
