摘　　要：设计了一种应用于时间敏感网络(Time Sensitive Network,TSN)端系统的队列管理器电路,它由缓冲区管理器和队列调度器构成。缓冲区管理器采用链表结构管理16个基于流的逻辑队列和8个基于优先级的逻辑队列,针对每个逻辑队列设置了独立的临时指针缓冲区,用以实现TSN所要求的对数据帧读出时间的精确控制;队列调度器同时支持门控机制、基于信用的整形器(Credit Based Shaper,CBS)调度算法和严格优先级调度算法;调度参数可以灵活配置。三者有机结合,可以满足不同类型用户业务接入TSN网络的需求。This paper designs a queue manager circuit used in end-station for TSN(Time Sensitive Network),which consists of buffer manager and queue scheduler.The buffer manager uses a linked list to manage 16 flow-based logical queues and 8 priority-based logical queues,and sets up an independent temporary pointer buffer for each logical queue to realize the accurate control of data frame readout time required by TSN;The queue scheduler supports gate control mechanism,CBS(Credit Based Shaper)transmission selection algorithm and strict priority transmission selection algorithm.Scheduling parameters can be configured flexibly.The organic combination of the above three can meet the demands of different types of traffic accessing the TSN.
