Grid computing is an important mechanism for utilizing distributed computing resources. These resources are distributed in different geographical locations, but are organized to p...
Abstract— Peer-to-Peer (P2P) systems provide decentralization, self-organization, scalability and failure-resilience, but suffer from high worst-case latencies. Researchers have ...
Given two replication schemes old X and new X , the Replica Transfer Scheduling Problem (RTSP) aims at reaching new X , starting from old X , with minimal implementation cost. In ...
In this paper, we discuss and compare several policies to place replicas in tree networks, subject to server capacity constraints. The client requests are known beforehand, while ...
