Abstract

The invention belongs to the field of computer technology, and discloses a high-efficiency data center networking method and system in transmission demands. The method comprises the following steps: collecting the transmission demands of computer nodes in a data center, and organizing into a two-dimensional table; networking all computers; networking all switches S; and when a plurality of switches T are adopted, needing to repeat all the switches T for networking until networking of all switches is finished. Through adoption of the method disclosed by the invention, the network structure canbe optimized better according to the data transmission demand, and data transmission is allocated evenly throughout the network, thus preventing an individual switch from becoming the bottleneck of transmission.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a high-efficiency data center networking method and system for transmission requirements. Background technique [0002] Deploy N computers in the data center, and every two computers have network transmission requirements. Traditional data center networking methods often adopt a fixed structure. For example, a classic data center often adopts a fat tree structure, and the Fat-tree has a total of three layers of switches: the core level, the aggregation level, and the edge level. [0003] Since the traditional fixed network structure does not take into account the data transmission requirements between computers, the obtained structure often cannot support data transmission well, that is, some switches may undertake a large amount of data transmission, and become the backbone of the entire network. bottleneck. [0004] To sum up, the problems existing in the exist...
