چکیده

Tolerating byzantine faults on a large scale is a challenge: in particular, Desktop Grid environments sustain large numbers of faults that range from crashes to byzantine faults. Solutions in the literature that address byzantine failures are costly and none of them scales to really large numbers of nodes. This paper proposes to distribute task scheduling on trusted nodes in a Cloud network and to have these nodes assess the reliability of worker nodes by means of a reputation system. The resulting architecture is built for scalability and adapts costs to the workload associated with client requests.

Enhancing Byzantine fault tolerance using MD5 checksum and delay variation in Cloud services

Cloud computing is an attempt to stretch the operation boundaries dynamically on-demand which is not the case with traditional distributed system. This unprecedented nature of cloud though offers various benefits it also has a downside when it comes to fault tolerance since most of the faults experienced by the cloud are unpredictable and thus Byzantine in nature. Byzantine faults in cloud comp...

Testing Byzantine Faults

Byzantine fault is a cumulative term given to the set of both permanent and transient faults caused in circuits which effectively present themselves as different errors at different nodes in the same circuit. Such faults have become significant with the shrinkage in node (process) technology with process variations, radiation strikes and quantummechanical effects being majorly responsible for c...

A Scalable Byzantine Fault Tolerant Service in Grid System

This paper describes the design, implementation and usage of a secure scalable Byzantine fault tolerant MDS system in the Grid. The scalable Byzantine fault tolerant MDS system provides a hierarchy GIIS servers, a local GIIS domain can require the resource it needs from remote GIIS domain. By using the statemachine replication approach and quorum system technique, the scalable Byzantine fault t...

Consensus When All Processes May Be Byzantine for Some Time

Among all classes of faults, Byzantine faults form the most general modeling of value faults. Traditionally, in the Byzantine fault model, faults are statically attributed to a set of up to t processes. This, however, implies that in this model a process at which a value fault occurs is forever “stigmatized” as being Byzantine, an assumption that might not be acceptable for long-lived systems, ...

Stabilizing Link-Coloration of Arbitrary Networks with Unbounded Byzantine Faults

Self-stabilizing protocols can tolerate any type and any number of transient faults. However, in general, self-stabilizing protocols provide no guarantee about their behavior against permanent faults. This paper considers self-stabilizing link-coloring resilient to (permanent) Byzantine faults in arbitrary anonymous networks. First, we show that stabilizing link-coloring is impossible in anonym...
