| Popis: | The redundancy protocol for Ethernet (RPE) has been developed to provide seamless redundancy for Ethernet networks. The RPE is suitable for Ethernet-based time-critical and mission-critical systems that require fault tolerance and high availability. However, the main drawback of the RPE is that it still generates redundant unicast traffic in Ethernet networks. In this paper, we propose an enhanced version of the RPE, called the enhanced RPE (eRPE), to reduce the redundant unicast traffic in Ethernet networks. The purpose of the eRPE is to establish dual paths for each connection pair of switches in Ethernet networks. To avoid a single point of failure, the dual paths have no common switch nodes between them. These paths are then used to forward the unicast frames in Ethernet networks (instead of flooding the frames as in the RPE). In this paper, the traffic performance of the eRPE is analyzed, evaluated, and compared to that of the RPE. Several simulations were conducted using the OMNeT++ simulator in order to validate the performance analysis. The analyzed and simulated results show that the eRPE significantly reduces network traffic compared to the RPE, thus saving a significant amount of network bandwidth as well as improving network traffic performance. |
