Data center network routing method capable of tolerating error connection

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of data center networks, in particular to a data center network routing method that tolerates wrong connections. Background technique [0002] In order to solve the shortcomings of traditional tree topology such as poor scalability, single point of failure, and large oversubscription, many "rich connection" topologies have been proposed in recent years, such as Fat-Tree, VL2, and so on. A notable feature of these new topologies is the abundant link resources introduced. But this also introduces a new problem. As the network scale continues to increase, the complexity of connections also increases accordingly when building a physical network. Taking the Fat-Tree network as an example, the data center network built with 48-port switches contains a total of 27,648 servers and a total of 82,944 links. It is conceivable that when a physical network of this scale is built by engineers, incorrect connections wil...
