Measuring the Quality of Service of Optimistic Replication
نویسندگان
چکیده
Optimistic replication has become an important tool in modern systems, allowing both read-only and read-write object accesses to continue even in the face of network outages and disconnected mobile computing. The quality of service delivered to a user by an optimistic system has traditionally been measured in terms of the rate of connicting updates. We show that this measure does not accurately assess the user's requirements, and propose new criteria for evaluating optimistically replicated systems.

A Simulation Framework for Evaluating Replicated Filing Environments
Optimistic replication of data is becoming increasingly popular in distributed systems. However, the performance characteristics of such systems are not well understood. We have developed a flexible and extensible simulation framework to investigate the operating costs and service quality of optimistic replication for file systems. This paper describes the simulator and presents the results of ...
متن کاملA Hybrid Protocol for Replicas Management in Data Grid
In large scale distributed systems, replication is a popular technique for improving the accessibility of information and surviving the unreliability of communication networks. Pessimistic replication and optimistic replication are two contrasting replication models. They represent the two extremes in the availability-consistency. Pessimistic replication favors consistency over availability, wh...
