QoS Multi-path Routing Scheme Based on ACR Algorithm in Industrial Ethernet

摘要

Network congestion is the determinant of network transmission delay. The QoS differentiated multi-path routing mechanism is proposed in this paper to balance the network load of industrial Ethernet, under the limited network resource condition. ACR algorithm is used to obtain the path sets for data transmission with different QoS requirements. The mathematical model of differentiated multi-path routing algorithm in industrial Ethernet is established and described in detail. Furthermore, key metrics involved in design is analyzed deeply. Difficulties in implementation based on ACR algorithm is pointed out, and the solution is given in specific description.
