Signal characteristic information for networks

A non-transitory computer-readable medium storing instructions, the instructions comprising:

• one or more instructions that, when executed by one or more processors of a device, cause the one or more processors to:
• receive a first network topology message from a first network device associated with a network path,
• the first network topology message including a mandatory set of fields including:
• first network topology information regarding the first network device, and
• a type-length value (TLV) field that includes signal characteristic information;
• generate a second network topology message after receiving the first network topology message,
• the second network topology message including:
• a mandatory set of fields including second network topology information regarding the device, and
• information regarding an adjustment to a parameter of an optical signal based on the signal characteristic information,
• the parameter being at least one of:
• a transmission power,
• a shape of the optical signal, or
• a bias loop;
• and
• transmit the second network topology message to a second network device of the network path.

A method, comprising:

• receiving, by a device, a signal via a network path and from a network device;
• determining, by the device, a characteristic of the signal based on receiving the signal;
• including, by the device, information identifying the characteristic of the signal in a type-length value (TLV) field of a message,
• the message being associated with conveying network topology information associated with the network path;
• and
• transmitting, by the device, the message to the network device to cause an adjustment to a parameter of the signal based on the information identifying the characteristic of the signal,
• the parameter being at least one of:
• a transmission power,
• a shape of the signal, or
• a bias loop.
