Abstract
A method for advertising a bit error includes that an intermediate node in a first tunnel detects that a bit error rate of a packet sent through the first tunnel exceeds a threshold; and the intermediate node sends a first packet to an egress node in the first tunnel through the first tunnel, where the first packet indicates that a bit error has occurred in the first tunnel, the first packet further instructs the egress node to send a second packet to an ingress node in the first tunnel, and the second packet indicates that the bit error has occurred in the first tunnel. The foregoing method can be used to transfer bit error information, so as to implement associated protection switching of services.
Claims20
A method implemented by an intermediate node in a first tunnel, wherein the method comprises:
- detecting that a bit error rate of a first packet sent through the first tunnel exceeds a threshold;
- and
- sending, to an egress node in the first tunnel, through the first tunnel, and in response to the detecting, a second packet indicating that a bit error has occurred in the first tunnel,
- wherein the second packet instructs the egress node to send, to an ingress node in the first tunnel, a third packet indicating that the bit error has occurred in the first tunnel.
A method implemented by an egress node in a first tunnel, wherein the method comprises:
- receiving, from a first intermediate node in the first tunnel and through the first tunnel, a first packet when a first bit error rate of a second packet sent through the first tunnel exceeds a first threshold, wherein the first packet indicates that a bit error has occurred in the first tunnel;
- and
- sending, to an ingress node in the first tunnel and based on the first packet, a third packet indicating that the bit error has occurred in the first tunnel.
An intermediate node in a first tunnel and comprising:
- a memory configured to store instructions;
- and
- a processor coupled to the memory and configured to execute the instructions to cause the intermediate node to:
- detect that a bit error rate of a first packet that sent through the first tunnel exceeds a threshold;
- and
- send, to an egress node in the first tunnel, through the first tunnel, and in response to the detecting, a second packet indicating that a bit error has occurred in the first tunnel,
- wherein the second packet instructs the egress node to send, to an ingress node in the first tunnel, a third packet indicating that the bit error has occurred in the first tunnel.
An egress node in a first tunnel and comprising:
- a memory configured to store instructions;
- and
- a processor coupled to the memory and configured to execute the instructions to cause the egress node to:
- receive, from a first intermediate node in the first tunnel and through the first tunnel, a first packet when a bit error rate of a second packet sent through the first tunnel exceeds a threshold, wherein the first packet indicates that a bit error has occurred in the first tunnel;
- and
- send, to an ingress node on the first tunnel, a third packet indicating that the bit error has occurred in the first tunnel.
