摘　　要：Elanix是和欣操作系统(Elastos)在Linux上的构件化虚拟操作系统,ElanixServer是其中的内核对象服务模块。针对Ela-nix中内核对象的构件化特性,提出了ElanixServer的通信机制,设计并实现了其通信层次,包括:实现各内核对象的主体层、构件化设计的接口层、使用元数据的列集层、基于设备文件的传输层。分析了此通信机制的优点,测试表明ElanixServer对应用程序请求的响应时间明显少于WineServer的响应时间,这为Elanix内核对象与应用程序之间的通信提供了有效途径。Elanix is the component-based virtual operation system of Elastos on Linux. Elanix server provides kernel object services for applications. In this paper, a communication mechanism of Elanix server is proposed for the component-based kernel objects. The design and Implementation of the communication mechanism are presented in detail. It contains four layers including body layer, interface layer, marshal layer and transfer layer. The advantages of the communication mechanism are analyzed. A test result shows Elanix server has a better performance than wine server, and proves the mechanism is an efficient approach for communication between Elanix kernel objects and applications.
