Abstract
A node device according to the present invention includes an adjustment unit (GMPLS control unit) for, when an anomaly occurs on a route toward another node device, adjusting weighting of the route, and performs routing in Generalized Multi-Protocol Label Switching (GMPLS) control based on the adjusted weighting.
Claims21
An optical transmission system which comprises a plurality of node devices, wherein
- each of the plurality of node devices comprises an adjustment unit for, when an anomaly occurs on a route toward another node device, adjusting weighting of the route, and
- each of the plurality of node devices performs routing in Generalized Multi-Protocol Label Switching (GMPLS) control based on the adjusted weighting.
A node device, comprising
- an adjustment unit for, when an anomaly occurs on a route toward another node device, adjusting weighting of the route, wherein
- the node device performs routing in Generalized Multi-Protocol Label Switching (GMPLS) control based on the adjusted weighting.
A GMPLS control method for transmitting and receiving optical signals by Generalized Multi-Protocol Label Switching (GMPLS) in an optical transmission system that includes a plurality of node devices, the method comprising:
- adjusting weighting of a route toward another node device in each of the plurality of node devices when an anomaly occurs on the route, wherein
- each of the plurality of node devices performs routing in GMPLS control based on the adjusted weighting.
A recording medium having recorded thereon a program to be executed by a computer in a node device which transmits and receives optical signals to and from another node device by Generalized Multi-Protocol Label Switching (GMPLS), the program comprising:
- an adjustment process of, when an anomaly occurs on a route toward another node device, adjusting weighting of the route, wherein
- the program causes the node device to perform routing in GMPLS control based on the adjusted weighting.
An optical transmission system which comprises a plurality of node devices, wherein
- each of the plurality of node devices comprises adjustment means for, when an anomaly occurs on a route toward another node device, adjusting weighting of the route, and
- each of the plurality of node devices performs routing in Generalized Multi-Protocol Label Switching (GMPLS) control based on the adjusted weighting.
A node device, comprising
- adjustment means for, when an anomaly occurs on a route toward another node device, adjusting weighting of the route, wherein
- the node device performs routing in Generalized Multi-Protocol Label Switching (GMPLS) control based on the adjusted weighting.
