The invention provides a data center network routing method capable of tolerating error connection. The method comprises the following steps that a Fat-Tree data center network topology structure is constructed; a centralized controller is configured, and the centralized controller is communicated with each server or interchanger in the Fat-Tree data center network topology structure; physical network mapping and logical network mapping are performed on the Fat-Tree data center network topology structure, and physical topology information is obtained; the centralized controller collects the list information of edge layer interchangers at which each interchanger can arrive through respective ports, and a corresponding objective edge layer interchanger list is the generated for each interchanger; the centralized controller calculates and installs corresponding routing table entries for arriving at each edge layer interchanger for each interchanger according to the generated objective edge layer interchanger lists. The data center network routing method capable of tolerating the error connection has the double advantages of efficiently utilizing network resources and improving the network throughput.
