【NTT】 DIPS-106-10OS --- integrated OS supporting small scale system

In the 1980s, data communication systems evolved into distributed-processing network systems through the increased sophistication of communication networks and on-premise equipment. This sophistication was due to reduced prices for processing equipment as a result of the advancement of LSI technologies and the expanding geographical spread of areas and places in which data were generated/used. The performance of a network distributed-processing system is substantially affected by allocation of functions between the center hosts and nodes in the network and by the integration of their operation and maintenance. Therefore, the development of the DIPS network OS (DIPS-106-10OS) aimed to decrease the restrictions on allocating functions and enhance the efficiencies in developing and maintaining software as well as those of operating and maintaining the network system.

DIPS-106-10OS, which was designed and developed based on the conventional DIPS-104-03OS, extended the supporting processor range to the small-size DIPS-V series. With this, the integration of software development environments and the common utilization of software between mid-to-large-scale and small-scale DIPS computer series was achieved, while the network operation and maintenance function capabilities were extended. As the result, the overall capabilities were significantly expanded, e.g., by extending the adaptability of the OS to further large-scale information processing and by enhancing the Japanese language processing function.

In mid-1984, DIPS-106-10OS was deployed into small-scale systems such as hospital information management systems, telephone network design and deployment management systems, and the INS-model systems. It was also introduced into large-scale systems, such as scientific and engineering computing systems, the information processing center of Tokyo postal service, the social insurance online data center system, a telephone exchange center migration support system, and a subscriber billing operation system.
