Abstract:
This paper classifies CoGIS into synchronous CoGIS and asynchronous CoGIS for the first time. By explaining the system structure and function module, it proposes a CoGIS prototype based on T.120 data conference system, and analyzes the hierarchical structure of the prototype and the synchronous procedure in detail. This paper offers a feasible scheme for realization of CoGIS system in further.
Key words:
CoGIS; T.120; Synchronous CoGIS; Asynchronous CoGIS; Network model; Level model
摘要： 首次把CoGIS 分同步CoGIS 和异步CoGIS 两类，进一步阐述体系结构、功能模块，提出基于T.120 数据会议系统的CoGIS 原型，并详细分析了原型的层次结构和同步流程。进一步丰富了CoGIS 的外延和内涵，并为CoGIS 系统的实现提供了切实可行的方案。
