“…The reason is that the binary strings are naturally encoded into their topology thus those are global [29][30][31]. k-cubes are analyzed in different networking fields such as data center networks, interconnection networks, WDM networks etc [31][32][33][34][35][36]. However, this type of topology has not been studied yet in the field of ERMs.…”

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.

SUMMARYThe exchanged hypercube, denoted by EH(s, t), is a graph obtained by systematically removing edges from the corresponding hypercube, while preserving many of the hypercube's attractive properties. Moreover, ring-connected topology is one of the most promising topologies in Wavelength Division Multiplexing (WDM) optical networks. Let R n denote a ring-connected topology. In this paper, we address the routing and wavelength assignment problem for implementing the EH(s, t) communication pattern on R n , where n = s + t + 1. We design an embedding scheme. Based on the embedding scheme, a near-optimal wavelength assignment algorithm using 2 s+t−2 + 2 t /3 wavelengths is proposed. We also show that the wavelength assignment algorithm uses no more than an additional 25 percent of (or 2 t−1 /3 ) wavelengths, compared to the optimal wavelength assignment algorithm.

A novel approach for an efficient network-on-chip using a modified Fat Tree is presented. Contention is eliminated and latency is reduced through an improved topology and router architecture. The adopted topology increases performance without a substantial increase in the routing cost. This is achieved by using an improved buffer-less, paremeterizable router architecture. The proposed router architecture is simple to implement yet can achieve the required packet collision avoidance. Simulation results that show the level of performance achieved by both the topology and the router architecture are presented. A throughput of more than 90% is achieved way above the 40-50% usually seen in other networks on chips.
