Zero-Touch Multi-Service Provisioning With Pluggable Module-Type OLT in Access Network Virtualization Testbed

This paper investigates a multi-service activation procedure for telecommunications carriers' zero-touch provisioning workflows using access network virtualization technologies in an optical access network. We examine a procedure in which one network function or a set of functions is initiated depending on the services to be activated after a line is automatically opened in response to a customer's action. The feasibility of this procedure is experimentally verified in a joint testbed environment between three Asia-Pacific telecommunications carriers. The results showed that even when 32 customers simultaneously request service activation, it takes less than 30 seconds for all of the customers' requests to be completed. In addition, we discuss potential implementations for activating various multi-service provisioning in response to customer requirements and network isolation in terms of virtualized resources and infrastructure. We also propose an implementation that utilizes network resources shared by various services more efficiently than that presented in our previous conference report, and we experimentally verify its feasibility. In addition, the experimental configurations briefly described in the previous report are described in detail in this paper.
