An Overview on the Integrated IP Optical Data Control Plane in the Optical Transport Network

In recent years, the Optical Transport Network (OTN) systems have been introduced widely, however, wide adoption has been limited due to the immature infrastructural issues. The OTN infrastructure takes the responsibility of data and signal transmission for substratal layer, as well as provides carrying and maintaining services (mostly the IP-based traffic today) through an optical data transport control plane. Thus, this paper focuses on the latest OTN data control plane and therefore gives a comprehensive introduction on the integrated IP Optical peer control plane.
