API based inter-node control plane communication infrastructure

An optical transport network, comprising:

• a source node, comprising:
• a first field replaceable unit comprising a first module processor and a first module memory comprising a non-transitory processor-readable medium storing processor-executable instructions and a control plane application that may be executed by the first module processor;
• a first node controller comprising a first controller processor and a first controller memory comprising a first non-transitory processor-readable medium storing processor-executable instructions and a first communication application that when executed by the first controller processor cause the first controller processor to:
• instantiate a first messaging network having a first messaging client and a first messaging server;
• register a first application plugin associated with the control plane application of the first field replaceable unit with the first messaging network;
• register a first application interface comprising at least a callback function and operable to communicate with the control plane application of the first field replaceable unit via a second messaging network;
• receive, by the first application interface via the second messaging network, a request from the first module processor executing the control plane application;
• transmit the request, via the first application plugin, to the first messaging client;
• receive a response via the first messaging client, the response being associated with the request;
• and
• transmit, by the first application interface, the response to the first module processor via the second messaging network;
• and
• a remote node, comprising:
• a second node controller comprising a second controller processor and a second controller memory comprising a second non-transitory processor-readable medium storing processor-executable instructions and a second communication application that when executed by the second controller processor cause the second controller processor to:
• instantiate a third messaging network having a third messaging client and a third messaging server;
• receive the request from the first messaging client via the third messaging server;
• generate the response to the request;
• and
• transmit the response to the first messaging client via the third messaging server.
