The move towards nanoscale Integrated Circuits (ICs) increases performance and capacity, but poses process variation and reliability challenges which may cause several faults on routers in Networks-on-Chips (NoCs). While utilizing healthy routers in an NoC is desirable, faulty regions with different shapes are formed gathering faulty routers. Fault regions can be used to lead the fault-tolerant...

Quantum dot Cellular Automata (QCA) is one of the important nano-level technologies for implementation of both combinational and sequential systems. QCA have the potential to achieve low power dissipation and operate high speed at THZ frequencies. However large probability of occurrence fabrication defects in QCA, is a fundamental challenge to use this emerging technology. Because of these vari...

This paper proposes a framework for automated evaluation and minimization of concurrent online checkers, with the aim of both achieving minimal fault detection latency, while at the same time maintaining the fault detection capabilities and keeping area consumption within the acceptable range. The proposed framework can be utilized for any digital circuit, however, our focus in this work as a c...

In this paper, we propose a fault management with fast rerouting restoration scheme in MPLS network. The proposed scheme finds out the root cause of the occurred fault, and provides differentiated service with guaranteed QoS (Quality of Service) according to the differentiated backup path options. It can provide various backup path options, such as 1:1, 1:N or M:N fast-reroute by NMS, and opera...

Understanding and modeling the factors that underlie the growth and evolution of network topologies are basic questions that impact capacity planning, forecasting, and protocol research. Early topology generation work focused on generating network-wide connectivity maps, either at the AS-level or the router-level, typically with an eye towards reproducing abstract properties of observed topolog...

The work established that an essential solution for proactively ensuring fault tolerance of networks is the support load balancing both at transport network level and access using FHRP. However, FHRP based on manual settings, which impose high requirements administrator’s professional training experience level. Therefore, task improving mathematical models methods make up algorithmic basis faul...

Fault Tolerance must be provided to increase system reliability. Combining efficiency with fault tolerance is a difficult task. Fault Tolerance requires the use of redundancy while efficiency requires the elimination of redundancy. Several fault tolerance techniques have been proposed in the literature to manage the redundancy existing in the system in order to provide fault tolerance. These te...

Computing systems have steadily evolved into more complex, interconnected, heterogeneous entities. Ad-hoc techniques are most often used in designing them. Furthermore, researchers and designers from both academia and industry have focused on vertical approaches to emphasizing the advantages of one specific feature such as fault tolerance, security or performance. Such approaches led to very sp...

This work proposes a fault-tolerant dynamic routing algorithm that employs maximum flow evaluation for route selection, increasing the number of disjoint paths to the destination, enhancing the path redundancy, and so extending the possibility of using detours, or alternative paths if needed. Route distance is employed as a secondary criterion. Routes may be dynamically changed by intermediate ...
