Technical complexity posed by the analog nature of long distance DWDM optical communications has driven the need for the current vertically integrated solutions in the market. ODTN’s approach is designed to change this by assuming that every optical link will use a matched pair of transponders from a single vendor. However, unlike single vendor solutions, the network can use a different brand of transponder for each link, and these transponders can run over an open line system from yet another vendor.
Leveraging the ONOS SDN Controller, ODTN will automatically and transparently discover the disaggregated components and will control the entire transport network as a unified whole, thus enabling multi-vendor choice. ODTN will rely open industry standards like TAPI (Transport API) and OpenConfig to achieve a truly vendor-neutral solution.The ODTN project will start with relatively simple point-to-point open line systems to more complex network scenarios, and end with a meshed network consisting of disaggregated optical equipment.
