Methods and apparatus for implementing optical integrated routing with traffic protection

摘要

In some embodiments, an apparatus includes a switch device that can be operatively coupled to a network having a set of links. The switch device can receive at a first time, a message having a set of physical coding sublayer (PCS) lanes. The message can include an error notification within a first subset of PCS lanes from the set of PCS lanes and not within a second subset of PCS lanes from the set of PCS lanes. The error notification is associated with signal degradation of a link from the set of links, where the switch device can send a first signal in response to receiving the message at the first time. The switch device can also receive at a second time a message without the error notification, and the switch device can send a second signal in response to receiving the message at the second time.

主权项

1. An apparatus, comprising:
a switch device configured to be operatively coupled to a network having a plurality of links, the switch device configured to receive, from an optical switch device at a first time, a message having a plurality of physical coding sublayer (PCS) lanes, the message including an error notification within a first subset of PCS lanes from the plurality of PCS lanes and not within a second subset of PCS lanes from the plurality of PCS lanes mutually exclusive from the first subset of PCS lanes, the error notification in response to signal degradation of a link from the plurality of links, the switch device configured to send a first signal in response to receiving the message at the first time, the switch device configured to receive at a second time a message without the error notification, the switch device configured to send a second signal in response to receiving the message at the second time.
