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:在網路系統中，節點緩沖區內消息發生覆蓋或溢出會造成消息的丟失，對于限時令牌網路，節點消息發送時間和消息緩沖容量的分配是影響消息實時性的重要因素.針對令牌傳遞網路分析了節點消息緩沖機制，說明了消息緩沖容量的確定與網路帶寬分配方法的關系，並提出了消息緩沖容量的確定方法，導出了避免消息覆蓋或溢出所需的最大發送和接收緩沖容量余度.指出在消息的產生間隔大於該消息的最大允許的延遲時間和接收節點響應時間的條件下，發送和接收端的消息緩沖容量等於被緩沖消息的長度 -
