Abstract: Techniques for negotiating optical configuration parameters of transceivers are disclosed. In one example, a method may include outputting, by a first optical node to a second optical node, a negotiation request message that specifies a configuration parameter setting for optical transceivers, the setting comprising one of a speed, a forward error correction (FEC) scheme, a modulation type, a transmission power, a minimum central frequency, a maximum central frequency, a minimum input power, a maximum input power, or a signal-to-noise ratio threshold; receiving, by the first optical node from the second optical node, in response to the negotiation request message, a negotiation response message including an indication of support for the configuration parameter setting; and configuring, by the first optical node, in response to the indication of support, a configuration parameter of an optical transceiver for the first optical node with the configuration parameter setting for the configuration parameter.

Abstract: A first device may provide, to a second device, a first message that includes a first request for a first type of precision time protocol (PTP) message and a second request for a second type of PTP message. The first device may receive, from the second device, a second message based on the first message. The second message may identify whether the first request and the second request are granted. The first device may provide, to the second device, a third message that instructs the second device to provide a first set of messages, associated with the first type of PTP message, and a second set of messages associated with the second type of PTP message. The first device may synchronize a first clock of the first device with a second clock of the second device based on the first set of messages and the second set of messages.
