Abstract
The invention provides to an avionics network high speed data loading and unloading method, and solves the problem that in an avionics network data loading and unloading technology, the loading and unloading efficiency is low. A new file transfer protocol based on a UDP is provided, when data are transferred by the file transfer protocol, the maximum size of a data package is negotiated by a data sender and a data receiver, the maximum size, which can be transferred, of the data package is obtained, and then the data can be transferred by using the maximum size of the data package. A receiving end does not confirm each data package independently, but confirm the received data packages uniformly after a plurality of data packages are transferred, data packages which are not received correctly are identified in a confirmed package, and therefore the number of data packages to be confirmed in the process of transferring the data packages is reduced. After the data receiver receives the confirmed package, the data packages which are not received correctly are retransferred, and the data transferring efficiency is improved through reducing the number of the data packages to be confirmed.
Description
Technical field
The invention belongs to computer communication technology field, relate to avionics network high speed data and add discharging method.
Background technology
In the exploitation, operation and maintenance process of avionics network, often need to carry out files loading or file download operation to designated equipment.Propose new data file upload and download method herein, comprise online equipment search operation, upload file operation and download file operation.
Current existing air net data add unloading agreement Arinc615A and there is the not high problem of efficiency.Owing to carrying out confirmation response for each packet, to cause adding discharge rate slow, and each packet full-size is restricted to 512 bytes, causes efficiency comparison low, therefore can not meet the transmitting data file demand of airborne equipment big data quantity.
Summary of the invention
Object of the present invention: in order to support that the upload and download of large-data documents is applied, proposing new data file upload and download method, adding discharge rate to improve data to greatest extent.
Technical scheme of the present invention:
A kind of avionics network high-speed data add discharging method, and its special character is: comprise the following steps:
1] startup adds/uninstall process;
2] transmit leg and recipient hold consultation, and determine the full-size of the packet that once can transmit;
3] sending direction recipient sends packet;
4] recipient's receiving step 3] packet that sends, recipient judges whether packet is correctly received, and identifies the packet be not correctly received, and recipient continues to receive packet; The packet be correctly received is stored in buffering area;
5] packet size received as recipient adds up to reach step 2] middle full-size of consulting, send to transmit leg and confirm to wrap, in this confirmation bag, identify all packets be not correctly received;
6] transmit leg receives and checks and confirms bag, retransmits the packet be not correctly received to transmit leg;
7] recipient receives the packet of re-transmission, is stored in buffering area;
8] step 3 is repeated to step 7, until add/completion of discharge.
The advantageous effect that the present invention has:
(1) data transmission bauds is high, by adopting new application layer protocol, drastically reduce the area the expense of acknowledge packet, improve efficiency of transmission;
(2) data transmission efficiency is high, by increasing packet full-size, improve link utilization, further reducing the expense of data input and data output, improve transmission speed, thus can meet the application demand of avionics Internet Transmission large-data documents of new generation.
Accompanying drawing explanation
Fig. 1 is new Data Transport Protocol flow process;
Fig. 2 is the flow process of transmit leg deal with data;
Fig. 3 is the flow process of recipient's deal with data.
Embodiment
A kind of avionics network high-speed data add discharging method.Search for online equipment, the operation of the upload and download of data file, propose the new file transfer protocol (FTP) based on UDP, this agreement is when transmitting data, receiving terminal is not independently confirm each packet, but after transmitting some packets, confirm all packets received are unified, identify all packets be not correctly received in this confirmation bag, which reduces in data transmission procedure the quantity confirming packet.After transmit leg receives this confirmation bag, retransmit those incorrect packets received, thus confirm that the quantity of packet improves data transmission efficiency by reducing.
As Fig. 1, concrete steps are as follows:
1] startup adds/uninstall process;
2] transmit leg and recipient hold consultation, and determine the full-size of the packet that once can transmit;
3] sending direction recipient sends packet;
4] recipient's receiving step 3] packet that sends, recipient judges whether packet is correctly received, and identifies the packet be not correctly received, and recipient continues to receive packet; The packet be correctly received is stored in buffering area;
5] packet size received as recipient adds up to reach step 2] middle full-size of consulting, send to transmit leg and confirm to wrap, in this confirmation bag, identify all packets be not correctly received;
6] transmit leg receives and checks and confirms bag, retransmits the packet be not correctly received to transmit leg;
7] recipient receives the packet of re-transmission, is stored in buffering area;
8] step 3 is repeated to step 7, until add/completion of discharge.
The flow process of transmit leg deal with data is as Fig. 2; The flow process of recipient's deal with data is as Fig. 3, and recipient receives a packet, checks that whether this packet is complete, if packet is complete, this packet is saved in buffering area; If packet is imperfect, this packet is marked in confirmation bag, by this data packet discarding or this packet is left come but do not use, recipient continues to receive next packet, until the packet size that recipient receives adds up to reach the full-size of consulting in step 2, send to transmit leg and confirm bag, again accept the packet of the re-transmission that transmit leg is sent, by complete packet writing in files system.
The present invention increases each packet size, require in TFTP agreement that packet is maximum and be no more than 512 bytes, in this agreement, first data input and data output side holds consultation to packet full-size, obtain the maximum packet size transmitted, next full-size data bag just can be used to transmit.
Notebook data adds discharging method, proposes 3 kinds of data files and adds unloading operation, comprise online equipment search operation, upload file operation and download file operation.
First define data and add the 3 kinds of operations unloading and comprise:
Online equipment search operation, loading end sends request order, after equipment online in network receives this solicit operation, the device id of oneself, positional information etc. is assembled, sends to loading end.Like this, loading end just can obtain all online equipment in network.
Upload file operates, and local file, by after searching and getting online equipment, is uploaded to the online equipment of specifying by loading end.First loading end sends files passe request, and the receiving equipment of specifying is responded, and represent and receive this file transfer, loading end starts to send data file, and receiving equipment verifies file after end of file transfer.
Download file operates, and loading end is from designated equipment download data files, and this data file can be fixing file, also can be the file that loading end is specified.First loading end sends file download request, and the receiving equipment of specifying is responded, and contains the Data Filename that can download simultaneously, next carries out the download of data file, and after having downloaded, the file of loading end to all downloads verifies.
This technology can be generalized in other communication networks.
