The all information of STL file is remained in this format and the data redundancy is reduced as possible, the length of compressed STL file is reduced to the 1/3 to 1/2 of original binary STL file. It is convenience for the file transmitting of network manufacturing.
As the Peer-to-Peer system has a great application prospect on file sharing, the Peer-to-Peer file transmitting problemhas become a crucial research problem in recent years.
This system can provide application program sharing, information communication, file transmitting and a safe network collaborative design environment for designers.
The information on agriculture is a kind of resource and computer network is the efficient vehicle for the information transmission. In the article, the problem of resource sharing was discussed and a proposal of file transmitting based UDP was presented.
We need a new kind of convenient,efficient and unpolluted file transmitting method. This paper presents a UDP-based method which can be used in LAN under the TCP/IP environment.
In order to improve the data redundancy and inconvenience of STL file, the authors advance a new STL data file storage format - compressed STL format. In this format the vertexes are sorted by z, y, x axes and stored sequentially, then the index of triangle face to vertex are established and stored. The all information of STL file is remained in this format and the data redundancy is reduced as possible, the length of compressed STL file is reduced to the 1/3 to 1/2 of original binar...

This paper supplies some file-transmitting methods based on TCP in the network environment. When the file is too big, it must be segmented for transmission, and the client and the server should control the data stream through cooperation rather than through loop. It also provides its realization under the circumstances based on Delphi language. Meanwhile, it analyzes the functions and performances of the methods by practical tests. It concludes that the system will be in a better working c...
