Experimental Demonstration of End-to-End Service Orchestration Architecture based on Northbound API

End-to-end interoperability between different vendors is fundamental for network operators to take advantage of all features of SDN. However, the chimney deployment of operator network cannot efficiently support the end-to-end service distribution and centralized maintenance requirements. Therefore, it is important to realize end-to-end service provisioning and agile opening for operators. This paper first introduces the proposed end-to-end orchestration architecture based on cloud-network collaboration. And then we briefly introduce the corresponding microservice architecture and the northbound interface of OTN network and IP network controller. Meanwhile, this paper demonstrates and validates the provisioning of constrained connectivity end-to-end services in multi-domain and multivendor SDOTN networks based on Extended ACTN Interface Model. The demonstration results show that access OTN equipment can decoupled with Metropolitan area network (MAN) OTN equipment, and it can realizes the low-cost and fast access of private line service on the orchestration system.
