Abstract
High-availability Seamless Redundancy (HSR) is a redundancy protocol that provides duplicated frames for separate physical paths with zero recovery time. HSR is suitable for time critical applications in Industrial Ethernet Networks. However, the existing HSR scheme makes the unnecessary traffic by redundant frame copies. This drawback will degrade the network performance and may cause network congestion or delays. Thus, we propose a packet transmission scheme with different periods based on HSR ring topology for reducing network traffic load. Since it uses different transmission period by IEC 61850 traffic types, it can be adaptive for smart grid automation network technology. The main idea of the proposed scheme is using a different packet transmission period on each port of the HSR node. On one port near to destination, the node sends packets with the default transmission period, which is the same with the existing HSR scheme. On the other port, the node sends packets with an extended transmission period according to the delay requirement of IEC 61850 traffic types. By using the extended transmission period, the proposed scheme can reduce the network traffic and retain HSR network’s availability. Also, we evaluate the proposed scheme by using OPNET simulation tool. The performance evaluation results show that the proposed scheme is better than the existing HSR scheme
