ODTN ProjectODTN (Open and Disaggregated Transport Network) is an ONF (Open Networking Foundation) project that aims to rally service providers, hardware vendors and system integrators, to● Build a reference implementation using (a) open source software, (b) open and common
data models, and (c) disaggregated hardware devices.● Perform lab and field trials using the reference implementation.● Identify supply chain gaps and propose solutions.
