Performance measurements of Motorola's implementation of MAP

摘要: The authors present performance measurements for data transfer services at the CASE (common application service elements), transport, and datalink layers of Motorola's implementation Manufacturing Automation Protocol (MAP) a range message sizes. They compare results using stop-and-wait vs. sliding window protocol, find that permits 40% speedup. observe end-to-end latency exceeds transmission delay by factor 25 1000-byte messages, thereby making all network access, transmission, propagation delays negligible when compared to protocol processing. show throughput transport is basically linear with size whereas not. identify bottlenecks which constrain total system each layer. >
