MHS中MS的研究与实现

文电作业系统是一种基于计算机网络的新通信业务。它可用于交换多种类型的信息，同时，还可以作为其它诸如电子数据交换等业务的通信支撑。ＣＣＩＴＴ为ＭＨＳ制定了Ｘ．４００系列建议也制定了相应的ＭＯＴＩＳ标准，文电存贮器是Ｘ．４００系列建议追加的ＭＨＳ的可选功能单元，本文介绍了作者参与实现Ｘ．４００系列建议ＭＨＳ课题中的文电存贮器实现的工作，提出了一种在ＳＵＮＵＮＩＸ系统中基于ＩＳＯ开发环境的实现文电存贮器

The Study and Implementation of MS in MHS

MHS (Message Handling System) is a new communication service, which is developed on the basis of the computer network. It is used to exchange many kinds of messages, and can also be used as a backbone for other communi- cation services, such as EDI (Electronic Data Interchange). The CCITT has for- mulated the standardization of MHS, which finally results in the X. 400 series of recommendations (84 and 88 versions), and the ISO was defined a series of stand- ards for Message Oriented Text Interchange Systems (MOTIS). The MS (Message Store) is an additional functional entity in MHS for X. 400 series of recommenda- tions (88 version). This article introduces the author's primary work on MS (in- cluding MS local functions and the MS access protocol P_7) in anticipating the MHS project for the realization of X. 400 series of recommendations (88 version), and offers a method to implement the MS system on the basis of ISO Development Environment-ISODE 7.0 in the SUN-UNIX system.
