A data center network based on prism structure

Abstract

A data center network based on a prism structure. Eight switches form a triangular prism unit network structure, including six five-port switches and two four-port switches. First, the top and bottom surfaces are composed of three five-interface switches connected in pairs to form an equilateral triangle with side length L. A four-interface switch is added to the center of the two equilateral triangles respectively, and connected with the other three The two switches are connected in pairs, the switches corresponding to the upper and lower bottom are connected in pairs, and then the three switches at the vertices of the triangle on the bottom are connected to the switch in the upper right corner in turn to form a basic network topology unit. Every switch is connected to a server except the switch in the center of the triangle. Expanding in this manner can form a vertically connected data center network with a base length of NL and h unit layers, where h and N are integers greater than or equal to 1.

Description

technical field [0001] The invention relates to a data center network topology structure, in particular to a data center network based on a prism structure. Background technique [0002] With the rapid development of cloud computing and computer-intensive network technology, the world has entered an era of rapid information development. According to the data released by the International Data Corporation: As of 2018, the number of servers in Tencent's data center has reached 50 Microsoft has 2 million, and Amazon's data center has nearly 3 million servers. When such a large number of servers work simultaneously, a large amount of data will be generated, and the data center network as its infrastructure has become a research hotspot again. How to connect these servers through connecting devices and high-speed links to form a data center network with high performance and provide high-efficiency and high-quality services for the upper-level computer system is definitely a majo...

Problems solved by technology

Although these structures solve the single point of failure problem of the traditional tree structure to a certain extent, they still have disadvantages such as expensive core switches and core routers, poor fault tolerance and poor scalability.
