一种新颖的突发交换网络混合组装算法研究

Study on a novel hybrid assembly algorithm for burst switching networks

提出一种新颖的混合组装算法来实现对到达网络边缘节点的IP数据进行突发组装。低流量时,采用FAP算法改善数据延迟特性;高流量时,采用AAS算法防止由于阻塞而产生的突发丢弃。仿真结果表明,混合组装算法在保证网络较低的阻塞率的同时,有效改善了数据突发在边缘节点的排队延迟特性。

In this paper, based on the feature of the Fixed assembly Period （FAP） algorithm and the Adaptive Assembly Size （AAS） algorithm, a novel hybrid assembly （HA） algorithm is proposed to assemble some IP packets into a burst at the edge switching nodes of an optical burst switching network. In the HA algorithm, being a state of light load, the algorithm FAP reduces the delay of a burst; in order to avoid the birth of burst drop caused by congestion, the AAS algorithm is adopted under high load of an edge node. By using the HA algorithm, the simulation results show that the characteristic of edge queuing delay of a burst is improved efficiently. At the same time, a low burst blocking probability of network is also guaranteed.
