| 8. | Abstract : in a network system , overflow or overwrite of message buffer will cause missing of messages . for a timed token network , message transmission time and the message buffering space allocation in a node are very important issues on network real time capability . this paper analyses the message buffering mechanism , describes the relationship of message buffering space and message transmission bandwidth allocation , and proposes a space determination method of message buffer for ltpb network . the maximum space redundancy avoiding buffer overflow for “ send ” and “ receive ” buffers has been derived . it is found that the space of “ send ” and “ receive ” buffers is equal to the message size under condition that the message gap time is greater than message latency and node response time
文摘:在网络系统中，节点缓冲区内消息发生覆盖或溢出会造成消息的丢失，对于限时令牌网络，节点消息发送时间和消息缓冲容量的分配是影响消息实时性的重要因素.针对令牌传递网络分析了节点消息缓冲机制，说明了消息缓冲容量的确定与网络带宽分配方法的关系，并提出了消息缓冲容量的确定方法，导出了避免消息覆盖或溢出所需的最大发送和接收缓冲容量余度.指出在消息的产生间隔大于该消息的最大允许的延迟时间和接收节点响应时间的条件下，发送和接收端的消息缓冲容量等于被缓冲消息的长度 |

| 10. | We study the qos strategy in wireless networks . after understanding the wireless local network based on ieee 802 . 11 , we point out the problem that occur when a large msdu ( mac service data unit ) is to be sent in the dcf mode in wireless lan . when a msdu is divided into several mpdus ( mac protocol date unit ) , the later mpdu will service as a important role
在此基础上，我们研究了无线局域网中的服务质量策略，在对基于ieee802 . 11的无线局域网进行了充分了解的基础上，提出了在无线局域网dcf方式下发送较大msdu [ 2 ] （ mac层服务数据单元）时会遇到的问题，指出当把msdu分片[ 2 ]成为一组mpdu （ mac层协议数据单元）进行发送时，随着mpdus的不断发送，排序靠后的mpdu将对整个msdu的发送时间产生决定性影响。 |
