Data center network topology structure, and determination method and system

Abstract

The invention relates to a data center network topology structure, a determination method and a system. A server comprises a plurality of connection ports, and a switch comprises n ports; a topological structure of the 0th layer of an inline network topological structure comprises one switch and n servers; one switch is directly connected with the n servers; the topological structure of the 0th layer is the topological structure of the bottommost layer; the topological structure of the lth layer comprises the topological structure of the t<l-1>+1 layer; the t<l-1>/2 servers in the topological structure of the ith (l-1)th layer are connected with the servers in the topological structure of the (l-1)th layer at different positions respectively; t<l-1> is the number of the servers in thetopological structure of the (l-1)th layer. The data center network topology structure provided by the invention solves the problems of low data transmission efficiency and low reliability in the prior art.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a data center network topology, a determination method and a system. Background technique [0002] In recent years, due to the rapid growth of data, the requirements for server computing speed and capacity have also continued to increase, so that many large data centers are constantly being built and expanded to solve these problems and better provide Online applications and services, such as search, e-mail, instant messaging, and the era of web2.0. In addition, these data centers also host infrastructure services such as: distributed file systems, structured storage, and distributed execution engines. In this work we focus on the network infrastructure inside the data center, which connects a large number of servers through high-speed links and switches, which we call the data center network (DCN). [0003] DCN has three design goals. First, the network infrastructure mu...
