摘要
首先简述Internet的服务质量保证能力的不足,分析了区分服务的网络系统模型和实现机制,然后提出一种边界结点采用基于TSW的三色标记算法和核心结点采用自适应RIO算法相结合的支持区分服务的路由队列调度和管理方案。最后对该方案的带宽资源使用效率进行分析,能够保证各个流聚集在共享带宽资源的公平性。
The paper first discusses some problems of current network service, and analyzes network system model and implementation mechanism. It then presentes an implementing scheme of router queue scheduling and management for supporting Diary. In the scheme, based on Time Sliding Window algorithm, the edge nodes use TSWTCM algorithm, while the core nodes use Adaptive-Random Early Detection with In and Out algorithm. Finally, by analyzing the utilization of network resource, the scheme can assure the fairness of bandwidth sharing among aggregated traffics very. well.
