Reconfigurable optical demultiplexer calling framework based on gRPC Design

Reconfigurable optical splitter multiplexer (ROADM) devices are the core devices for current optical network interconnection and dense wavelength division multiplexing. In this paper, the Google Remote Procedure Call (gRPC) protocol is investigated for the shortcomings of low transmission rate, poor transmission efficiency and only local calls when communicating with RESTful and TCP protocols mainly used in the current ROADM device software calling system. A reconfigurable remote procedure call framework for optical splitter and multiplexer based on the gRPC protocol was implemented using C language. The shortcomings of the ROADM device call system in terms of transfer rate, transfer efficiency and the fact that only local procedure calls can be made have been improved. Test results show that the use of the gRPC protocol has effectively improved the transmission rate and efficiency of the RODAM device and enabled remote procedure calls.
