碩士 === 國立成功大學 === 工程科學系 === 82 === In NIXE environment, new thoughts on designing network protocols, network topology, and user interface are required. It is the motivation of this study to design and implement an Object-Oriented Communication Server(OOCS) which enforces the requirements --performance, and reliability--on top of the Parton kernel. OOCS supports an object-oriented network communication mechanism to facilitate message transmission between Object-Oriented Support Subsystems (OOSSs) and other system objects in NIXE. The primary aspects of OOCS are the user interface, software framework, and protocol implementation. OOCS provides a user-level Courier object, which supports the appropriate OO API (Object-Oriented Application Program Interface) for users to achieve the high- performance, and high-reliability network communication. The software framework is a new architecture that is designed by Object-Oriented Methodology for implementing network protocols. The current network hardware topology is Ethernet and OOCS processes message transmission between network hosts by point- to-point and/or group communication functions. In addition, VMTP, IP protocols are implemented by following the Object- Oriented Methodology concept. It suffices to provide an exmaple for implementing ordinary network protocols by OO Methodology and for further enhancement of OOCS.
