B-ISDN中用户网路接口处的流量控制分析

Performance Analysis of Generic Flow Control at User Network Interface in B ISDN

以ＢＩＳＤＮ用户网路接口处的澳式ＧＦＣ规程为中心，在多个终端共享媒介各终端信源采用马氏调制流体模型的情形下，讨论了本规程在对称双点总线结构下的有关ＧＦＣ控制．结果表明：各终端之间的距离对各类业务终端不构成决定性影响，最终影响各终端带宽分配的决定性因素还是终端的带宽均衡参数β和业务流整形参数γ，因此可以根据各终端的业务质量要求，对β。

The generic flow control of symmetric structure of the Australian protocol of GFC at UNI in B ISDN is presented. When using MMFM as input source model, in the case of shared medium configuration, we find that the distance between terminal equipments is not the essential factor in the GFC mechanism, however, β and γ are essential to the bandwidth allocation.
