Abstract: Improving on the priority control in Fibre Distributed Data Interface (FDDI) can both ensure the sending of high priority of cells as most as possible,and prevent the condition that the low priority of cells which can’t be sent for long time.Simulation results show that the improved FDDI protocol can satisfy the quasi-fairness of priority control of Integrated Service Digital Networks(ISDN).

摘要: 对FDDI优先级协议进行了改进,既尽可能保证高优先级信息的发送,又防止出现低优先级信息(特别是优先级最低信息)长时间得不到发送的局面。模拟实验验证,改进的FDDI协议能够满足综合业务数字网优先级准公平性要求。
