一種高效的分布式QoS路由算法的研究

Study of an Efficient Distributed QoS Routing Algorithm

  • 摘要: 該文提出了一種以帶寬為度量標準，改進的分布式QoS路由算法，它不僅繼承了分布式QoS路由算法簡單、鏈路開銷小的優(yōu)點，而且可以減少網(wǎng)絡(luò)處于重負荷時所產(chǎn)生的資源碎片，接納更多的業(yè)務(wù)。同時，通過確定本算法的啟動門限，可以在保證算法性能的同時，大大降低引入的路徑建立時延。計算機仿真結(jié)果證明了這種算法的正確性和高效性。
    Abstract: A novel distributed QoS routing algorithm, the metric of which is bandwidth, is presented in this paper. It not only keeps the merits of simplicity and low link overhead in traditional distributed QoS routing algorithm, but also can reduce resource fragments and admit more services into a network with heavy load. The high performance of this algorithm accompanies some delay during path setup. But the performance remains with great reduction in this delay when the start threshold of this algorithm is considered. The extensive simulation results also indicate its correctness and efficiency.
