SDN Based Network Path Planning Optimization for Printing Cloud Service

With the rapid development of information technology and the widespread application of cloud computing, cloud printing services have become an efficient and convenient printing solution, widely used in modern offices and corporate environments. However, as the scale of cloud printing services expands and users’ expectations for service quality increase, the system faces several challenges. Among them, monitoring the status of resources such as computing, storage, and application services, as well as reliable data transmission path planning, have become critical issues. In response to these challenges, this paper aims to provide intelligent printing terminal routing strategies for Zhuhai Xinye Electronic Technology Company, ensuring comprehensive reliability for different levels of business transmission. This study proposes a QoS-aware path planning mechanism based on Software-Defined Networking (SDN) to address the prioritization and packet loss issues during the massive real-time data transmission in cloud-edge collaboration. The mechanism allows flexible adjustment of network resource demands and priorities for different levels of business through SDN. Additionally, it incorporates blockchain technology to store path planning and alert issuance flow table information, ensuring the traceability of business path and alert information.
