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 implement a verilog-based learning rout...

Grid Computing allows coordinated and controlled resource sharing and problem solving in multi-institutional, dynamic virtual organizations. Moreover, fault tolerance and task scheduling is an important issue for large scale computational grid because of its unreliable nature of grid resources. Commonly exploited techniques to realize fault tolerance is periodic Checkpointing that periodically ...

Process groups are a common abstraction for fault-tolerant computing in distributed systems. We present a security architecture that extends.Abstract Concerns about both security and fault-tolerance have had an important. Tion of fault tolerance will face some of the same problems, and benefit from. The security testing prototype is.A Secure and Fault-tolerant framework for Mobile. Of Computer ...

In dynamic systems that adapt to users’ needs and changing environments, dependability needs cannot be avoided. This paper proposes an orthogonal fault tolerance model as a means to manage and reason about multiple fault tolerance mechanisms that co-exist in dynamically adaptive systems. One of the key challenges associated with dynamically evolving fault tolerance needs is the feature interact...

changes in the physicochemical conditions of process unit, even under control, may lead to what are generically referred to as faults. the cognition of causes is very important, because the system can be diagnosed and fault tolerated. in this article, we discuss and propose an artificial neural network that can detect the incipient and gradual faults either individually or mutually. the main fe...

we present an approach to design of fault tolerant computing systems. in this paper, a technique is employed that enable the combination of several codes, in order to obtain flexibility in the design of error correcting codes. code combining techniques are very effective, which one of these codes are turbo codes. the algorithm-based fault tolerance techniques that to detect errors rely on the c...

A proper support for multimedia communications transport has to provide fault tolerance capabilities such as the preservation of established connections in case of failures. While multi-homing addresses this issue, the currently available solution based in massive BGP route injection presents serious scalability limitations, since it contributes to the exponential growth of the BGP table size. ...

The incorporation of fault tolerance techniques into robot systems improves the reliability, but also increases the hardware and computational requirements in the overall system. It is not always clear how to evaluate the merit, orèeectiveness' of diierent fault tolerance approaches for a given application. In this paper, we present a new set of performance criteria designed to measure and comp...

In this paper, we present an ‘emulation environment’ for the design and planning of QoS-enabled IP networks. Specifically, QoS support for real-time traffic in future IP networks require ‘fault tolerance’ for mission-critical applications such as tele-medicine. Based on this premise, our goal is to design the QoS network system for the traffic management so that QoS requirements are satisfied. ...

The recursive training algorithm for the optimal interpolative (OI) classification network is extended to include distributed fault tolerance. The conventional OI Net learning algorithm leads to network weights that are nonoptimally distributed (in the sense of fault tolerance). Fault tolerance is becoming an increasingly important factor in hardware implementations of neural networks. But faul...
