一种基于共享内存的消息总线设计与实现

Design and Implementation of A Kind of Message Bus Based on Shared Memory

针对现代数据信息通信方式中管道通信和Socket通信存在易阻塞和效率低的问题,文中利用共享内存空间原理,开辟由FRAG碎片和Block组成的缓冲池,设计了基于共享内存的消息总线通信方式。实验结果表明,该消息总线满足了数据信息通信中数据信息传递快速高效的要求,并具有较强的自适应能力。

Among current data communication modes, pipeline communication and socket communication are easy to be blocked. What＇s worse, their efficiency are low. In this regard, according to the principle of shared memory, this paper develops a buffer pool consisted of fragments and blocks and designs a message bus communication mode based on shared memory. The design result indicates that the message bus faciliates quick and efficient data transfer in data communication and has strong self- adaptability.
