电信级应用系统中多进程共享内存池的实现

随着电信3G时代的来临,基于3G的数据和增值业务将成为发展重点,因此对承担业务实时计费,鉴权等后台任务的系统之性能,提出了更高的要求。本文介绍了在实际应用中,在unix上的多进程处理模式下,为提高系统的处理性能,而设计的一个内存访问优化方案。该方案是对老系统的进程间数据交互部分功能进行重新设计,以期减少数据的内存拷贝,降低对操作系统内核的压力。完成改造后,经测试证明,在相同硬件配置情况下,性能得到显著提高。

Shared Memory Pool-A Solution for Telecom-grade Application

Value Added Service (VAS) will be hot spot in 3G network of telecom,which makes the backend system such as biling and authorization engine for VAS be more efficent.Here introduces solution for shared memory model accessing by multiple processes to improve application performance.This solution is intended to decrease memory copy of data by redesigning the data shared mechanism in processes. By testing for new version and compared to the old,performance is ismproved significantly under same environment.
