In recent years, many telecom operators suffered a profits recession because of the rise of over-the-top (OTT) services, especially text messaging and voice calls. To avoid becoming dumb pipes, telecom operators have to launch diverse digital services to transform their networks from dumb pipes to smart ones. Introducing Software-Defined Networking (SDN) into telecom networks may boost the network transformation more easily. SDN could also foster the innovation of novel telecom services, such as Software-Defined Wide-Area Network (SD-WAN) and Datacenter Interconnection (DCl). However, SDN also brings challenges to current network provisioning systems. It is needed to design a new network provisioning system to fulfill the demands of customers from their SD-WAN applications which need network controls. To provide dynamic network control, we design and implement a new service-oriented network provisioning system to support on-demand self-service network services. The system has been successfully deployed with the managed SD-WAN services in Chunghwa Telecom.
