Extensible data center network architecture and implementation method

Abstract

The invention discloses an extensible data center network architecture. An optical exchanger is adopted to replace a traditional electric exchanger. A machine frame (6), a ToR exchanger (5), a polymerization exchanger (4), a core exchanger (3) and a content exchanger (2) inside a data center are respectively grouped into different assemblies, then the assemblies are placed on a group of adjacent nodes in a backbone network in a remote and distributed mode, the data among the assemblies are switched and transmitted through optical fibers in the backbone networks, and therefore simplification of inside connection in the center of the data is effectively utilized and the extendibility of the data center network architecture is strengthened by means of a plurality of network infrastructures. The extensible data center network architecture further discloses an implementation method of the data center network architecture, grouping of the machine frame, determination of the number of the exchangers, placement of the assemblies, and solving problems of service routes are all summed up into an integral linear program, then a mathematical tool is utilized to carry out solving or the architecture is designed according to a heuristic algorithm, the design is flexible, and adaptability is strong.

Description

technical field [0001] The present invention relates to a data center network architecture, in particular to an expandable data center network architecture and an implementation method. Background technique [0002] A data center is a business support platform for cloud services and consists of a large number of servers. These servers are organized in the form of racks (Racks), and dozens to thousands of servers are usually placed on each rack to provide parallel computing and resource storage. There are data exchange requirements between servers on the same rack and different racks. To meet this need, the data center contains a multi-level switching network inside. [0003] Usually, a ToR (Top-of-Rack) switch is placed on the top of each rack in the data center, which is responsible for data exchange between servers in this rack and data exchange interfaces with other racks. ToR switches usually need to have packet header parsing and routing functions. Each ToR switch i...

Problems solved by technology

[0008] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a scalable data center network architecture and implementation method. The data network center adopts a distributed architecture, which solves the difficulty of power supply and heat dissipation caused by centralized placement in the traditional architecture. High cost and insufficient space, etc., with stronger scalability and lower energy consumption; two implementation methods are used to design and adjust the data center network architecture, with flexible design and strong adaptability
