“…In another effort, Allawi et al [4] studied the problem of minimizing the cost of HSR mesh networks given a network availability constraint. However, in this study, an inappropriate method that previously used in [7], is used to analyze the availability and hence has the same fundamental problems. Generally, in this work, redundant link topology, shared link topology, and complex shared link topologies have been studied.…”

“…Generally, complex shared link topologies have been studied in this work. Allawi et al [7] investigated the problem of design optimization namely trade-off between redundancy investment and the realization of the network availability demanded by the customer in HSR-based Ethernet mesh networks. In this work, to analyze the availability of the single-ring networks, he employed the same method as in [5,6].…”

“…In other words, in this case, there are the same problems as in [5,6]. Allawi et al [7] uses an estimated upper bound reliability equation presented in [18] for the calculation of multiple-ring mesh availability. However, this strategy is suitable for calculating the reliability not for availability since it can produces misleading results.…”

“…In addition, the high-availability seamless redundancy (HSR) presented by IEC 62439-3 is receiving attention due to its capability of providing better availability with a zero failover time [4]. However, this technique increases the number of links/special nodes such as HSR and quadruple boxes in the network, which increases CAPEX and OPEX [4,6,7]. Generally, the main principle of HSR is to duplicate frames and send them over disjointed paths at the same time [4].…”

“…In the meantime, reliability has always been considered as one of the basic parameters in Ethernet ring mesh networks (ERMs) [1][2][3][4][5][6][7][8][9][10][11][12]. However, regardless of using ERP or HSR schemes, an Ethernet single-ring mesh network cannot be fault tolerant in more than one link (i.e.…”

Reliable networking is an important factor in Ethernet ring mesh networks (ERMs) with ITU-T G.8032 Ethernet ring protection recommendation or with the IEC 62439-3 high-availability seamless redundancy protocol. However, there are two major challenges for this purpose: (1) Hitherto, irregular topologies are used in ERMs that it causes difficulty in analyzing and improving reliability. (2) A topology is appropriate for practical implementation, if it is low cost, simple to implement, and simple to develop for large scale-systems (i.e. scalable). However, irregular topologies are extremely difficult to implement and develop. To deal with these challenges, this paper introduces two regular topologies called chordal ring and k-cube networks, for the first time in the area of ERMs. In addition, the proposed topologies are carefully analyzed in terms of reliability. These analyzes prove that the proposed regular topologies outperform existing irregular multiple-ring networks namely shared link, shared node, complex shared link, redundant link, and 3-connected network.
