Development and application of whole-railway wagon flow routing services with EPOLL programming model

Institute of Information and Technology, China Railway Lanzhou Group Co. Ltd., Lanzhou　730000, China

摘要: 将原先采用标准C++语言开发的、运行于Win32操作系统上的车流径路系统移植到64 bit Linux操作系统中，采用Eclipse作为开发工具，基于Linux的I/O编程模型—EPOLL开发全路车流径路服务，形成全路车流径路数据集中计算和分布应用的新模式，支持车流径路数据的高并发访问和高效率传输；经过一年的运行监测，该服务运行稳定，已为多个应用系统提供全路车流径路共享数据。

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.
