主动网络节点资源管理策略研究

Resources Management Policy of Active Network Node Based on J_Sim

复杂的资源管理调度算法对主动代码的运行并不合适,相反会降低信包的传输速率.提出了一种基于组件的主动节点资源管理体系结构.讨论了主动信包的分类和封装格式.提出了一种多优先级短信包优先算法对信包进行调度,采用基于优先级的低带宽需求优先的算法对带宽资源进行分配管理,利用动态监测和静态限定的方法对内存进行管理.实验结果表明该资源管理机制符合主动网络的特点,能够对主动节点中的资源进行有效的管理,提高主动节点的性能.

Scheduling algorithm for complicated resources management is not fit for active code, it debases transmission speed of capsules. The authors propose resources management architecture of active network node based on components, and discuss the classification and encapsulation format. This architecture proposes scheduting algorithm of the shortest packet with multi-priority first to schedule capsules, assigns and manages bandwidth with low bandwidth first algorithm based on priority. It manages memory by dynamic supervising and static limiting capsule. Experimental results show that this management mechanism conforms to characteristics of active network. It effectively manages resources of active network nodes, and improves the performance of active network nodes.
