Reachability determination in wavelength division multiplexing network based upon fiber loss measurements

A method comprising:

• receiving, by a processor deployed in a telecommunication network, a request to establish a wavelength connection between a first node and a second node in the telecommunication network, the request including information on an expected duration of the wavelength connection;
• determining, by the processor, whether the second node is reachable from the first node using an acceptable loss value, wherein the acceptable loss value is based upon the expected duration of the wavelength connection;
• and
• configuring, by the processor, the telecommunication network based upon whether the second node is determined to be reachable from the first node.

A non-transitory computer-readable medium storing instructions which, when executed by a processor deployed in a telecommunication network, cause the processor to perform operations, the operations comprising:

• receiving a request to establish a wavelength connection between a first node and a second node in the telecommunication network, the request including information on an expected duration of the wavelength connection;
• determining whether the second node is reachable from the first node using an acceptable loss value, wherein the acceptable loss value is based upon the expected duration of the wavelength connection;
• and
• configuring the telecommunication network based upon whether the second node is determined to be reachable from the first node.
