基于RapidIO的实时CORBA中间件实现

摘要

In order to resolve the uncertain delay of CORBA traditional transport protocol TCP/IP, in this paper, a solution to replace TCP/IP with RapidIO technology based on end-to-end packet exchange is proposed and the pluggable transport protocol framework of CORBA is studied.So real-time CORBA middleware based on RapidIO is implemented.The test result shows that the real- time performance of CORBA based on RapidIO is superior to that of CORBA based on TCP/IE%为了解决CORBA传统传输协议TCP／IP的时延不确定问题，提出了使用基于点对点的包交换RapidIO协议来替代TCP／IP的方法，研究了CORBA的可插拔传输协议框架，从而实现了CORBA报文在RapidIO总线上的传输。测试结果显示，基于RapidIO的CORBA实时性优于基于TCP／IP的CORBA。
