Abstract
Provided are a network device for encoding automatic protection switching (APS) information and an operating method of the same. The operating method includes monitoring a state of a working path and, when a failure is detected on the working path, encoding network failure information for activating a protection path on an APS channel and transmitting the network failure information to another network device. The APS channel is divided into a plurality of fields. The plurality of fields includes a first field corresponding to at least one of failure state information and request state information, and the first field may be a field corresponding to protection type information.
Claims10
An operating method of a network device for encoding automatic protection switching (APS) information, comprising:
- monitoring a state of a working path;
- and
- when a failure is detected on the working path, encoding network failure information for activating a protection path on an APS channel and transmitting the network failure information to another network device,
- wherein the APS channel is divided into a plurality of fields,
- the plurality of fields includes a first field corresponding to at least one of failure state information and request state information, and
- the first field is a field corresponding to protection type information.
A network device for encoding automatic protection switching (APS) information, comprising:
- a transceiver;
- and
- at least one controller operatively connected to the transceiver,
- wherein the at least one controller is configured to monitor a state of a working path and, when a failure is detected in the working path, encode network failure information for activating a protection path on an APS channel and transmit the network failure information to another network device,
- the APS channel is divided into a plurality of fields,
- the plurality of fields includes a first field corresponding to at least one of failure state information and request state information, and
- the first field is a field corresponding to protection type information.
