Abstract
The present invention is a transmission system, a path control method, and a transmission device, and is the path control method in the transmission system forming a virtual concatenation group by virtually concatenating each path signal transmitted through a plurality of paths being a logical communication path, which manages an active state and a stand-by state of member paths of the virtual concatenation group and when there is abnormality in any of the member paths in the active state, controls any of the member paths in the stand-by state to the active state in place of the abnormal member path, thereby realizing more flexible and efficient path level redundancy.
Claims20
A transmission system that virtually concatenates each path signal transmitted through a plurality of paths being a logical communication path to form a virtual concatenation group, the system comprising:
- managing section for managing an active state and a stand-by state of member paths of the virtual concatenation group;
- and
- control section for controlling any of the member paths in the stand-by state to the active state in place of any of the member paths in the active state that has abnormality.
A path control method in a transmission system that virtually concatenates each path signal transmitted through a plurality of paths being a logical communication path to form a virtual concatenation group, the method comprising:
- managing an active state and a stand-by state of member paths of the virtual concatenation group;
- and
- controlling any of the member paths in the stand-by state to the active state in place of any of the member paths in the active state that has abnormality.
A transmission device on a receiving side for receiving a path signal from the transmission device on a transmitting side that virtually concatenates each path signal transmitted through a plurality of paths being a logical communication path to form a virtual concatenation group, the device comprising:
- managing section for managing an active state and a stand-by state of member paths of the virtual concatenation group;
- and
- control section for controlling any of the member paths in the stand-by state to the active state in place of any of the member paths in the active state that has abnormality.
