چکیده

The availability is often used to measure how well a system can provide the service continuously. The measures of availability for a single computer and for multiple computers are very different. In this paper, we discuss the objects set availability in the distributed environment especially in the case of P2P environment. The objects set availability is defined and formalized. In the P2P environment, the hosts are divided into groups by their availability values. Objects are evenly distributed among groups. The experiments show that such simple but practical method has good efficiency in achieving high objects set availability.

Self Organized Replica Overlay Scheme for P2P Networks

Peer-to-Peer (P2P) systems are widely used for data sharing applications in an autonomous and decentralized mode. P2P systems are suitable for largescale distributed environments in which nodes can share resources other than data such as computing power, memory and network bandwidth. Some of important parameters that affect the performance of P2P systems are peer availability, data availability...

On Improving the Performance Dependability of Unstructured P2P Systems via Replication

The ever-increasing popularity of peer-to-peer (P2P) systems provides a strong motivation for designing a dependable P2P system. Dependability in P2P systems can be viewed from two different perspectives, namely system reliability (the availability of the individual peers) and system performance (data availability). This paper looks at dependability from the viewpoint of system performance and ...
