Data center network topology structure and routing method thereof

Abstract

The invention discloses a data center network topology structure and a routing method of the data center network topology structure. The data center network topology structure comprises switches and servers. Each server comprises two network card ports. Each switch is provided with n ports. One switch is connected with n severs to form a partition structure at the bottommost layer of the topology structure. Half number of the server network card ports not used in each of n low-layer partition structures are connected to all the switches respectively to form a high-layer partition structure. The n server network card ports connected to all the switches are from the n low-layer partition structures respectively. In this way, the whole topology structure is formed recursively layer by layer. The data center network topology structure has the advantage of expandability and high fault tolerance.

Description

technical field [0001] The invention belongs to the technical field of the Internet, and in particular relates to a data center network topology structure and a routing method thereof. Background technique [0002] The data center network refers to the network infrastructure of the data center. It connects a large number of servers through high-speed links and switches. The data center network is the core infrastructure of the hardware part of the data center. Its topology structure provides all the switches in the data center. The connection relationship with the server determines the specific organizational form of the data center. [0003] With the development of digitalization of information resources, a large amount of data is generated every day in many fields such as industrial manufacturing, e-commerce, scientific research and teaching, life and entertainment. It is an inevitable trend of the development of today's era that the scale of data is getting larger and fa...

Problems solved by technology

[0004] At present, most data center networks are based on a tree structure, which has the following disadvantages: first, high-level switches or routers are likely to become bandwidth bottlenecks; second, core switches or routers are single points of failure in the system; third, high-end communication equipment Using will result in an expensive build

For example, Fares et al. proposed an improved tree structure Fat-Tree, which transforms the traditional tree structure through more cheap switches and connections, improves fault tolerance and network bandwidth, but its scalability is still Limited by the number of switch ports

The DCell proposed by Guo Chuanxiong of Microsoft Asia Research Institute has high scalability, fault tolerance and network bandwidth, but it uses more expensive multi-port network cards (such as four ports) and more complicated connection methods, which will increase Difficulty managing large deployments and resulting in higher build costs

FiConn proposed by Li Dan et al. uses cheap switches and dual-port network card servers, but it uses part of the performance loss in exchange for cost reduction.
