This paper proposes a new approach to providing fault tolerance in MPLS networks based on the concept of “domain protection” where protection paths for all working paths that terminate in an egress router are calculated simultaneously. The proposed scheme guarantees that every protected node is connected to two protection paths placed in a way that no single link failure would cause simultaneou...

Programmable networking is an increasingly popular area of research in both industry and academia. Although most programmable network research projects seem to focus on the router architecture rather than on issues relating to the management of programmable networks, there are numerous research groups (discussed in [55]) that have incorporated management middleware into the programmable network...

In building a multiprocessor system, we can minimize the system's mean time to failure by providing an architecture resilient to component faults. We compare the fault tolerance and performance characteristics of various fault-tolerant multistage interconnection networks. We primarily focus on networks composed of dilated routing components. A dilated router features redundant outputs in each l...

High throughput, low latency and high system availability are the most important criteria for an internet router. Internet Router‟s complexity has been on constant rise to serve the exploding internet backbone. With rise in design complexity comes the increased possibility of bugs escaping into silicon and affecting the user at runtime. In this project we provide a runtime verification scheme f...

With proliferation of the Internet and its services, how to provide stable and efficient Internet services via reliable high-speed network has become an important issue. Multihomed network is attracted much attention to provide stable and efficient Internet services. In this paper, we focus on the multihoming method in the IPv6 environment. In the IPv6 environment, each host can be assigned mul...

Network-on-Chip (NoC) is widely used as a communication scheme in modern many-core systems. To guarantee the reliability of communication, effective fault tolerant techniques are critical for an NoC. In this paper, a novel fault tolerant architecture employing redundant routers is proposed to maintain the functionality of a network in the presence of failures. This architecture consists of a me...

Brief Project Description: Fault-free design of electronic systems is becoming increasingly difficult due to variations in the silicon manufacturing process, requiring systems to be adaptive to faulty conditions post deployment. Researchers have looked to building brain-inspired computing architectures, based on Spiking Neural Networks (SNN), which aim to mimic the efficient and self-adaptive i...

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...
