Weighted voting for replicated data

David K. Gifford
1979 Proceedings of the seventh symposium on Operating systems principles - SOSP '79  
In a new algorithm for maintaining replicated data, every copy of a replicated file is assigned some number of votes.  ...  The reliability and performance characteristics of a replicated file can be controlled by appropriately choosing r, w, and the file's voting configuration.  ...  We have demonstrated a new algorithm for the maintenance of replicated data that offers many benefits not provided by previous solutions.  ...

Improving Statistical Word Alignment with Ensemble Methods [chapter]

Hua Wu, Haifeng Wang
2005 Lecture Notes in Computer Science  
On these two methods, both weighted voting and unweighted voting are compared under the word alignment task.  ...  Weighted voting performs consistently better than unweighted voting on different sizes of training sets.  ...  For weighted voting, the weights of word alignment links produced by the bi-directional word aligners are trained from the training data, which will be further described in section 5.  ...

focusing on a set of plots showing the estimated Republican vote share for whites and for all voters, as a function of income level in each of the states.  ...  subject matter is historical (and thus the replication data exist before the preregistration plan is written) and where the analysis is exploratory (and thus a replication cannot be simply deemed successful  ...  Because the telephone data set did not come with sample weights, we then rescaled the online data set sample weights so that the overall mean was 1.  ...

Decentralized weighted voting for P2P data management

Maya Rodrig, Anthony LaMarca
2003 Proceedings of the 3rd ACM international workshop on Data engineering for wireless and mobile access - MobiDe '03  
This paper presents a decentralized variant of David Gifford's classic weighted-voting scheme for managing replicated data.  ...  Weighted voting offers a familiar consistency model and supports on-line replica reconfiguration. These properties make it a good fit for applications in the pervasive computing domain.  ...  DECENTRALIZED WEIGHTED VOTING The original algorithm presented by Gifford was designed for systems in which replicated data is distributed across multiple servers and accessed by a single client.  ...

The performance of available copy protocols for the management of replicated data

Jehan-François Pâris, Darrell D.E Long
1990 Performance evaluation (Print)  
Available copy protocols guarantee the consistency of replicated data objects against any combination of non-Byzantine failures that do not result in partial communication failures.  ...  We are also grateful to John Carroll for his many contributions to this work. The second author is especially indebted to Ernestine McKinney for her assistance and encouragement.  ...  Acknowledgment We wish to thank Walter Burkhard, Keith Messer, Bruce Martin, Alexander Glockner and all the members of the Gemini group for their help and encouragement.  ...

Optimal binary vote assignment for replicated data

Her-Kun Chang, Shyan-Ming Yuan
2000 Journal of Systems and Software  
Weighted voting is a popular solution for maintaining the consistency. The performance of a voting system is determined by the vote assignment.  ...  Data replication can be used to improve the availability of data in a distributed database system. In such a system, a mechanism is required to maintain the consistency of the replicated data.  ...  Weighted voting (Giord, 1979) is a popular solution for synchronizing read and write operations to replicated data.  ...
