C/S 数据处理系统及其在 DECnet 上的实践

C/S Data Processing System and Its Application on DECnet

本文介绍了ＶＡＸ－ＰＣ构成的异构ＤＥＣｎｅｔ网络中实施Ｃ／Ｓ数据处理系统的一般方法，并以一个Ｃ／Ｓ方式核聚变实验数据处理系统为例，详细说明了ＶＡＸ－ＰＣ在ＤＥＣｎｅｔ环境下的Ｃ／Ｓ系统的实现方法。通过对ＶＡＸ集中式处理系统与Ｃ／Ｓ方式处理系统的性能评价说明了Ｃ／Ｓ方式的优越性。

Because of the rapid development of PC and LAN technology, C/S data processing paradigm became the mainstream of distributed processing. For the family of VAX which running VMS operating system, in order to implement a C/S system, we must solve some problems and take efforts to implement inter process communication between VAX and PC. In this article, we introduce how to construct a C/S system in the VAX PC heterogeneous environment. We also describe the practical method by an example. At last, the result of performance evaluation and comparison of the centralized processing and C/S system confirmed that the latter has some advantages.
