摘要: DQDB城域網(wǎng)是實現(xiàn)現(xiàn)有通信網(wǎng)絡(luò)向B-ISDN過渡的優(yōu)選網(wǎng)絡(luò)。本文分析了DQDB城域網(wǎng)用于計算機局域網(wǎng)互連時的排隊性能;研究了報文長度、網(wǎng)絡(luò)上下游負(fù)荷、帶寬平衡參數(shù)和網(wǎng)絡(luò)計數(shù)器級數(shù)對報文在緩存器中停留時間的影響。所得結(jié)果可為DQDB城域網(wǎng)的具體實現(xiàn)提供參考。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.
