For a hot issue of data center's research field in recent years.With the development of novel radio technology, by novel wireless communication
Technology is applied among data center, can effectively alleviate high energy consumption, autgmentability difference and deployment difficulty that data center is faced etc.
Problem.For example, 60GHz wireless communication techniques have transmission rate height, strong interference immunity, peace as a kind of Radio Transmission Technology
The features such as Quan Xinggao, high directivity, high transmission power of permission, but the technology is not suitable for long haul communication, and easily passed
The barrier on path is broadcast to hinder to propagate.
In order to which by novel radio Technology application, in wireless data hub network, researcher proposes to carry out nothing using principle of reflection
Line signal transmission.Using the reflex of reflecting plate, by some secondary reflections, signal is transferred to destination node from source node.
However, wireless signal can scatter, a part of signal cannot be transferred to destination node, other nodes can be interfered.
The content of the invention
The shortcomings that in order to overcome the above-mentioned prior art, it is an object of the invention to provide a kind of based on wireless data hub
Accurate reflection method, realizes the accurate reflection of wireless signal, solves the transmission distance that part New-type radio communication technology faces
From it is short, easily hinder to transmit by barrier the problems such as, while reduce the bar number of data communication, lift the transmission of wireless data hub
Performance.
To achieve these goals, the technical solution adopted by the present invention is：
A kind of accurate reflection method based on wireless data hub, server are arranged in server rack 1, server machine
Frame 1 is according in following regular arrangement wireless data hub place：
Each server rack 1 is respectively arranged in each vertex position of some concentric regular polygons, each server machine
(Top of Rack, abbreviation ToR) is provided with wireless signal transmitter and receiver on frame 1 top, in each bar of each regular polygon
The position on side sets reflecting plate 2, is provided with reflector space 5 and non-reflecting regions 4 on each reflecting plate 2, wireless signal passes through reflection
Region 5 is received by the receiver realization communication after reflecting, and the wireless signal scattered on non-reflecting regions 4 is absorbed.
Coated With Absorbing Material on the reflecting plate 2, and some uncoated vacancies are reserved in centre position, then coating zone
For non-reflecting regions 4, area of absence is reflector space 5.
The vacancy is the circle that radius is 5cm, and multiple vacancies are in line along the length direction of reflecting plate 2.
Source node and destination node position of the position of the reflector space 5 according to wireless signal, with reference to principle of reflection meter
Obtain so that the wireless signal that source node emits is beaten in reflector space 5, and destination node is sent to by reflection.
The wireless signal is reflexed to up to destination node after source node is sent by single or multiple.
Compared with prior art, the present invention can reduce the interference of data center, realize the precise delivery of wireless signal, lifting
The data transmission performance of wireless data hub, meanwhile, reduce the deployment of data center and safeguard consumption, for improving in data
The heart has very great meaning.

Embodiment
The embodiment that the present invention will be described in detail with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of accurate reflection method based on wireless data hub of the present invention, will be each based on principle of reflection
Server rack 1 is respectively arranged in each vertex position of some concentric regular polygons, each 1 top (Top of server rack
Of Rack, abbreviation ToR) wireless signal transmitter and receiver are provided with, set in the position on each bar side of each regular polygon
Reflecting plate 2.
As shown in Fig. 2, reflector space 5 and non-reflecting regions 4 are provided with each reflecting plate 2, specifically, on reflecting plate 2
Coated With Absorbing Material, and some uncoated vacancies are reserved in centre position, then coating zone is non-reflecting regions 4, vacancy area
Domain is reflector space 5.Vacancy is the circle that radius is 5cm in embodiment, and multiple vacancies line up one along the length direction of reflecting plate 2
OK.Wireless signal is received by the receiver realization communication after being reflected by reflector space 5, and scatters to the nothing on non-reflecting regions 4
Line signal is absorbed by absorbing material.
