The Consensus Recovery Block*
نویسنده
چکیده
In this paper. we review the two existing methods of producing fault-tolerant software and the;r associated reliability models. A new approach to software fault-tolerance, the Consensus Recovery Block, is proposed. Its reliability model 1S used to demonstrate its superiority over the conventional methods.

A Review on Consensus Algorithms in Blockchain
Block chain technology is a decentralized data storage structure based on a chain of data blocks that are related to each other. Block chain saves new blocks in the ledger without trusting intermediaries through a competitive or voting mechanism. Due to the chain structure or the graph between each block with its previous blocks, it is impossible to change blocking data. Block chain architectur...
متن کاملUTILIZING CONCEPTUAL MODELING IN THE STUDY OF ONE OF THE IRANIAN FRACTURED CARBONATE RESERVOIRS
A typical Iranian carbonate matrix block surrounded by an open fracture was modeled in order to understand the fracture-matrix interaction and realize how to model the interaction best. The modeling was carried out by using a fine-scaled Eclipse model in the single porosity mode (the fractures were explicitly modeled). The model was extended to a stack of 6 matrix blocks to understand block-to-...
متن کاملThe Reliable Hybrid Pattern A Generalized Software Fault Tolerant Design Pattern
In order to make software applications more reliable, it may be necessary to incorporate into them a strategy for tolerating software faults. In the case of critical applications, this is essential. In this paper we describe a general pattern, which we call the Reliable Hybrid pattern, that can be used to design fault tolerant software applications. The pattern supports development of applicati...
متن کاملSensitivity Analysis of Cumulative Oil Production and Production Rate on Block Heights and Capillary Continuity for an Iranian Carbonated Fractured Reservoir
Block heights and capillary continuity between matrix blocks play paramount role in the sensitivity analysis and therefore the history matching of cumulative oil production and production rate of carbonated fractured reservoirs. In this study, the influence of these parameters upon cumulative production and recovery factor of an Iranian fractured reservoir were studied by the usage of a sim...
متن کاملFuzzy Approach for Selecting Optimal COTS Based Software Products Under Consensus Recovery Block Scheme
Submitted in March 2010; Accepted in December 2010 Abstract The cost associated with development of a large and complex software system is formidable. In today's customer driven market, improvement of quality aspects in terms of reliability of the product is also gaining increased importance. But the resources are limited and the manager has to maneuver within a tight schedule. In order to meet...
