Abstract

Software-defined networking (SDN) is undoubtedly the trend in next-generation network technology development, but replacing all network devices with SDN-enabled devices in a short time is impractical for a full SDN environment construction. The smooth evolution of SDN networks is achieved by gradually replacing parts of the devices and making the traditional and SDN networks coordinated in operation. To address the issue of using SDN architecture in the enterprise network for migration, this article introduces a technique capable of ensuring edge switch migration without affecting the operation of the existing network. The developed technique provides the interface operating function of enterprise SDN, optimizes the mechanism of VLAN management and maintenance, and improves the maintenance performance of edge switch replacement. This article proposes the system architecture and key technologies developed through the enterprise SDN migration for the edge switch system. Then, the paper explains the intelligent control programs developed by the controller to construct the SDN migration technology. Furthermore, it introduces the system deployment architecture and service functions with the help of ITRI Information Technology Services Center for field trial actualization.
