Design of End-to-end Service Orchestrator System for Multi-technology Networks

Abstract

In the carrier’s dedicated line market, the end-to-end service orchestrator system for multi-technology networks is becoming increasingly significant. The functionalities and software infrastructure designs of China Unicom’s E2E service orchestrator system for multi-technology networks are described in this paper. On a unique method, this system uses the controller-on-demand path-calculation mode to achieve rapid service delivery in a flat SDN architecture. The paper also discusses the principal important technologies that were employed in the system development process.
