“…Cost is an important metric in the design of MINs, so that if a high-performance network have a high cost, then it would not be a suitable case for implementation. According to previous works [14,22,23,25,26,[28][29][30], a common method for estimating the cost of a MIN is calculating the number of crosspoints used in the network. Therefore, the cost is given by the number of crosspoints within a switching element and by the number of switching elements within the network.…”

“…Therefore, we are able to monitor the behavior of the proposed approach in terms of the improvement rate that occurred in the reliability parameter. In addition, like many previous works [14,22,23,25,26,[28][29][30], we will analyze the cost of network hardware to assess the second case. In the cost analysis, it will be assumed that the cost of a switch is proportional to the number of gates involved in it.…”

The use of multiprocessor systems is the main method for providing a high computational power. Multistage interconnection networks (MINs) are widely used to connect processors and memory modules in multiprocessor systems. Therefore, the design of an efficient MIN is an essential requirement for the development of multiprocessor systems. In addition, a critical parameter for any efficient interconnection network is reliability. However, the problem in the way of designing high-reliable interconnection networks is high hardware cost. To solve this problem, contribution of this paper is to propose a new approach to improve the reliability of the MINs, called the rearranging links. The proposed approach is implemented on two common MINs namely extra-stage shuffleexchange network (SEN+) and augmented shuffle-exchange network (ASEN). Meticulous analysis of terminal reliability proves that the proposed approach is an efficient method to improve the reliability of MINs. In addition, performed cost analysis confirms that utilizing it leads to emerge cost-effective MINs.

In today's access networks, the permutation of circuits connecting the subscriber lines to Plain Old Telephone Service (POTS) and to Digital Subscriber Line Access Multiplexers (DSLAMs) occurs in the Main Distribution Frame (MDF) and is still manually configured. However, new market regulations and new policies adopted by operators require increasingly more frequent permutations, making the manual configuration activity particularly expensive. Very recently, Automated MDFs (AMDF) have been developed to provide inexpensive and almost real-time switching capability. Our study, based on more than 50 years of research activities on architectures for circuit switching, is focused on overcoming the limits of classical architectures. In fact, strictly non-blocking multistage networks are too expensive, as a consequence of the large number of ports they require (sometimes exceeding 100,000). In addition, rearrangeable multistage networks can temporarily interrupt active circuits, affecting the performance of ADSL subscriber lines.As a possible solution to these problems, we propose the design of AMDFs based on Non-Interruptive Rearrangeable (NIR) networks. We show how to optimize the routing control to minimize the setup time of a circuit and to exploit output grouping. We believe that the solution described above is not only relevant for the theory of multistage interconnection networks, but also for the design and operation of large AMDFs.

“…Within sevenlayer communication architecture, it is the only layer that isn't fully automated. Specifically, within a contemporary access network, the arrangement of circuits that connect the subscriber lines to Plain Old Telephone Service (POTS) and Digital Subscriber Line Access Multiplexers (DSLAMs) is manually configured within the MDF [11]. As a large number of optical fibres are employed within conventional communication systems, operators need to provide end users with high-level reliability services, address line failures rapidly, and maintain affordable maintenance and operation costs.…”

In recent times, significant advancements have been evidenced in efforts to enhance connectivity and security within intelligent buildings (IBs). An IB is a contemporary structure that leverages state-of-the-art computer technologies to autonomously control the environmental conditions within a building to enhance occupants’ comfort, safety, work efficiency, and wellbeing while also ensuring optimal energy consumption. In the access aspect of a telecommunication network for IBs, the Main Distribution Frame (MDF) is in the central office. Intermediate Distribution Frames (IDFs) act as the isolation points for additional troubleshooting and further distribute the lines. The MDF is essentially a circuit switch that is typically operated through manual intervention because requests to establish or remove connections are sporadic and occasional. This can be tackled by utilizing Agent Based Systems (ABS) and Internet of Things (IoT) monitoring systems to develop a more holistic perspective of the process by which IDFs and MDF rooms are maintained. Furthermore, it will generate a process overview if we eradicate the process of physically checking a room that is currently used for IoT monitoring. In this research, a case study is presented to determine the feasibility of developing an IoT monitoring system. Currently, the monitoring applied in the case study is long, and over 40% of the equipment has maintenance failures. Distributed simulation of ABS is used to simulate the use of IoT for this project. Its data forecast can be very useful in determining the appropriate actions to improve the process of IDF and MDF and operational cost.
