Study on the Hierarchical Resource Management Policy for Core Transportation Network Nodes
Yi Zhang · Dianzi xuebao · 2004
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.
