摘要

网络节点的资源分配策略是影响未来IP核心传输网络服务质量的关键因素.本文针对网络节点的数据层面资源分配

提出了具有混合算法结构的分层调度算法、分层动态门限缓存管理机制.仿真结果表明采用分层资源分配策略

可以使网络节点系统在优先级在输出端口间分布不均衡情况下的数据转发率接近理论值.

Abstract

The resource management policy of network nodes is the key element to influence the Quality of Service (QoS) of the future IP core transportation network.In this paper

aimed to distribute the data path resource

a hierarchical scheduling algorithm with hybrid algorithm structure and a buffer management mechanism with hierarchically dynamic threshold are proposed.The simulation results show that when the hierarchical resource management policy is adopted

the forwarding rate will approximate the theoretical value under the situation with non-uniform priorities distribution among output ports.
