With complexity comes the need for more sophisticated automated network applications and orchestration software that can process large quantities of data, run complex algorithms, and adjust the routing state as required in order to support the network applications, their computations and their policies. Changes made to the routing state of a network by external applications must be verifiable by those applications to ensure that the correct state has been installed in the correct places.
