1.The effects of message length, traffic load of upstream and downstream nodes and the parameters of bandwidth balancing mechanism and network counters on the sojourn time of message in the buffer are investigated, which present a valuable reference for the implementation of DQDB MAN.
4.They improve the real-time performance of the Distributed Real-Time Interprocess Communication in some aspects such as buffer management and message queues managing.
5.②Implemented the sending of custom-built ARP detecting frame and reading of ARP buffer by coding, and fixed the discovery results of devices using corresponding algorithm; Moreover I implemented the distributed discovery of message based on ARP protocol.
