DQDB城域网实现计算机局域网互连时的性能分析
PERFORMANCE ANALYSIS OF DQDB MAN FOR LANs INTERCONNECTION
-
摘要: DQDB城域网是实现现有通信网络向B-ISDN过渡的优选网络。本文分析了DQDB城域网用于计算机局域网互连时的排队性能;研究了报文长度、网络上下游负荷、带宽平衡参数和网络计数器级数对报文在缓存器中停留时间的影响。所得结果可为DQDB城域网的具体实现提供参考。Abstract: DQDB metropolitan area network is a promising solution for the evolution from current networks to B-ISDN. The performance of DQDB MAN for LANs interconnection is analyzed. The effects of message length, traffic load of upstream and downstream nodes and the parameters of bandwidth balancing mechanism and network counters on the sojourn time of message in the buffer are investigated, which present a valuable reference for the implementation of DQDB MAN.
