摘要
简要分析了目前几种典型的节点操作系统实例的特征,选择遵循规范设计并对规范灵活运用的Moab实例进行分析,重点研究它的关键技术,特别是内存管理和受限的包缓冲机制为执行环境层实现细粒度的资源控制提供支持,另外,在信道协议规范中使用Click来扩展节点操作系统API,从而完美地实现灵活、高效的主动路由配置功能。
Briefly the paper analyzes the features of major NodeOS instances currently, aims at Moab implementation which is compliant with DARPA active network programs NodeOS specification and takes advantages of the flexibility of the specification, highlights several crucial techniques;especially for memory management and packet buffers mechanism which provide fine-grained resource control for execution environment, in addition, uses Click channels to extend the NodeOS channel API, realizing flexible and efficient active route configuration perfectly.
