| Abstract: | The existing wagon flow routing software built by C++ running in Win32 OS was transplanted into 64-bit Linux OS and Eclipse was used to encapsulate the software as the whole-railway wagon flow routing services with the I/O programming model EPOLL, which established a new mode of distributed-application and centralized computing of wagon flow routing data that could meet the need of high concurrent access and efficient data transmission. After one year running under monitoring, the whole-railway wagon flow routing services have been proven to be stable and capable of providing shared data of whole-railway wagon flow routing for multiple application systems. |
