Abstract

This paper presents and analyses a high performance manufacturing communication system. It consists in the standard TOP profile implemented in single processor computer connected to a LAN. High throughput is achieved by an efficient implementation architecture based on specific layer interfaces and data structures, specialized mechanisms of memory management, timer management and task scheduling. Performance measurement results show a throughput efficiency that attains 6 Mbit/s for a remote communication and 42 Mbit/s for loopback configuration. The most important bottlenecks are analysed and consist in the transport checksum, transport acknowledgment step frequency, LLC memory copy, memory management and task scheduling
