Abstract

The invention discloses a data center network topology system based on module expansion. And therefore, a problem that an expansion capability of tree topology of a data center is limited to the number of ports of a switch device and insufficiency of dynamic selectivity of a downlink can be solved. The implementation steps of system are as follows: an intermediate layer is introduced between a core layer and a convergence layer of a fat tree structure; a small network that is formed by connection of switches and servers of each of the layer is recorded as a basic module, so that a plurality of basic modules are constructed; four additional ports of switches of the core layer are utilized to connect all the basic modules to form a large whole network, so that a demand of construction of a data center network can be met and dynamic selection of a down link can be satisfied as well as a high halving bandwidth is provided; and lateral expanding, vertical expanding or mixing expanding is carried out on the network topology system as well as expansion of the network scale is supported flexibly. According to the invention, the system has a high network fault tolerance performance; more server devices can be accommodated; and a demand of application expansion in the future can be met; therefore, the system can be applied to construction of a data center network and high bandwidth data transmission can be provided.
