Today’s large-scale distributed systems consist of collections of nodes that have highly variable availability — a phenomenon sometimes called churn. This availability variati...
We consider the problem of ensuring high data availability in federated content sharing systems. Ideally, such a system would provide high data availability in a device transparen...

— The three traditional objectives of computer security are confidentiality, integrity and availability [8]. Availability can be defined as the prevention of denial of service. C...
High availability plays an important role in heterogeneous clusters, where processors operate at different speeds and are not continuously available for processing. Existing sched...
This paper presents a method of estimating the availability of fault-tolerant computer systems with several recovery procedures. A segregated failures model has been proposed rece...

In a software system, it is inevitable that components will occasionally fail to produce acceptable results and become unavailable to serve its clients. Replication is the techniq...
– Shared-backup path protection (SBPP) has been widely studied in the GMPLS networks due to its efficient spare capacity sharing and flexibility in service provisioning. This pap...
