Description
Technical field
The present invention relates to train communication technical fields, more particularly, to a kind of homogeneous network domain name management method.
Background technique
Currently, the modern means of communication (such as high-speed rail train) are usually formed by multiple compartments or unit spliced, each train
The element number for being included can be adjusted flexibly according to actual needs；From the point of view of producing angle, each unit factory configuration is identical,
Production difficulty can be reduced, production configuration difficulty is reduced；From the point of view of safeguarding angle, train is set as the rapid wear that high intensity uses
It applies, scene can be extremely important with independent maintenance or replacement, and each unit factory configuration is identical, and field replaceable can be greatly lowered
Difficulty reduces overall maintenance cost.Realize above-mentioned target, it is desirable that each terminal must map to one virtually inside train unit
Global I P (Internet Protocol, the agreement interconnected between network) address.It is each virtual complete in order to facilitate terminal communication
Office's IP address can all correspond to one or more DNS (Domain Name System, domain name system) domain name, the visit between terminal
It asks and is carried out by domain name.
The IP address of terminal actual disposition is private network IP, has to the complete of specified distant terminal across the IP communication between unit
Office's IP address is purpose IP, therefore, before practical communication, is needed by sending DNS request, ETBN to ETBN gateway
(Ethernet Train Backbone Node, Ethernet train backbone network node) gateway replys DNS request, provides specified whole
The global ip address at end, after the global ip address for obtaining distant terminal, it can message is sent to the IP address, via ETBN
Equipment does NAT (Network Address Translation, network address translation) conversion and routing forwarding, eventually arrives at mesh
Terminal, thus realize across unit communication.
IEC61375 protocol suite defines basic Train Communication Network, describes train Topology Discovery Protocol and DNS domain
Name specification, the DNS domain name format that IEC61375 agreement is recommended：Dev01.vel01.cst01.lTrn, wherein dev01 is equipment
Name, vel01 are compartment numbers, and cst01 is element number, and lTrn is train name；It is calculated by layer-by-layer matching unit position complete
Office's IP address.Using this DNS method, the DNS domain name of each equipment and the corresponding relationship of IP require to pass through configuration file
It is preconfigured into ETBN equipment, terminal device is increased or decreased and is also required to modification configuration file and updates to ETBN equipment, scene dimension
It is more complex to protect process.
The information disclosed in the background technology section is intended only to deepen understanding of the general background technology to the present invention, and
It is not construed as recognizing or implying in any form that the information constitutes the prior art known to those skilled in the art.
Summary of the invention
The purpose of the present invention is to provide a kind of homogeneous network domain name management methods, to solve column existing in the prior art
Vehicle communicates the problem of domain name management process complexity, especially when increasing or decreasing terminal device.
In order to solve the above technical problems, the present invention provides a kind of homogeneous network domain name management method, which includes
Following steps：
S1. the connection relationship between the ETBN of the multiple units of train is calculated by IEC61375-2-5 agreement, according to calculating
As a result, each ETBN is made to be arranged successively simultaneously given unit number；
S2. the network terminal of unit A sends DNS request message to its ETBN in train, the network terminal of request unit B
The format of global ip address, domain name message is：The element number of extra cell B after the private network IP address of the network terminal of unit B；
S3. network terminal return unit B from the ETBN to unit A the network terminal global ip address, the overall situation
IP address includes：The host bit of the network terminal of the network segment and unit B of the ETBN of unit B；
S4. the network terminal of unit A can be communicated by global ip address with the network terminal of unit B.
Further, the network terminal of the unit A is identical with the private network IP address of the network terminal of the unit B.
By adopting the above technical scheme, the present invention has the advantages that：
Homogeneous network domain name management method of the invention calculates global ip address using train private network IP mapping method,
Terminal only needs to submit the private network IP of distant terminal and element number can obtain the global ip address corresponding to it, domain name with
The corresponding relationship of global I P greatlies simplify maintenance cost without being preconfigured into ETBN equipment.
