Abstract
Disclosed is a method of determining, by a network manager, a failure in a ring communications network, including determining a plurality of ring segments within different services of a plurality of services using the ring communications network, determining that there are two or more link failures in the ring communications network, determining the ring segments where the two or more link failures are located, and indicating an interruption of one of the services when the two or more failed links are on different ring segments.

A method of determining, by a network manager, a failure in a bidirectional ring communications network, comprising:
- determining a plurality of ring segments within different services of a plurality of services using the bidirectional ring communications network;
- determining that there are two link failures in the bidirectional ring communications network;
- determining that the two link failures are located on different ring segments;
- indicating an interruption of one of the different services when the two failed links are located on the different ring segments;
- determining that the two link failures are not located on different ring segments;
- and
- reversing traffic flow in the bidirectional ring communications network and indicating no interruption of one of the different services when the two failed links are not located on different ring segments.
A network manager configured to manage a failure in a bidirectional ring communications network, comprising:
- a network interface;
- a memory device;
- and
- a processor in communication with the interface and the memory device, the processor being configured to determine a plurality of ring segments within different services of a plurality of services using the bidirectional ring communications network, determine that there are two link failures in the bidirectional ring communications network, determine that the two link failures are located on different ring segments, and indicate an interruption of one of the different services when the two failed links are on the different ring segments, determine that the two link failures are not located on different ring segments, and reverse traffic flow in the bidirectional ring communications network and indicate no interruption of one of the different services when the two failed links are not located on different ring segments.
