Abstract With the rise of mobile Internet and big data, the continuous expansion of data center network deployment, the trend toward more complex traffic patterns and fine-grained performance management requirements, have brought more and more network performance issues to the fore. As an emerging network architecture, SDN separates the control plane from the data plane, and has the characteristics of centralized control and programmable. The centralized control feature of SDN technology enables the SDN controller to dynamically obtain network topology, link information, node information, and flow information in a timely manner, thereby realizing flexible and fine-grained centralized scheduling of network flows, which is very suitable for the needs of data centers. Due to the high dynamic nature of SDN, how to improve the timeliness of its load balancing and better solve network congestion is very important. Aiming at the problems in data center network applications, this paper studies the SDN-based data center network load balancing management system structure, and discusses the load balancing technology of data center server clusters based on improved ant colony algorithm.
