To cope quickly with all types of failure risks (link, node and Shared Risk Link Group (SRLG)), each router detecting a failure on an outgoing interface activates locally all the backup paths protecting the primary paths which traverse the failed interface. With the observation that upon a SRLG failure, some active backup paths are inoperative and do not really participate to the recovery (sinc...

Making backup is so cumbersome and expensive that individuals hardly ever backup their data and companies usually duplicate their data into a secondary server. This paper proposes a novel Peer-to-Peer (P2P) backup system known as the SecureBackup service, which was defined in the DisPairse research project. It utilizes the unused personal hard disk spaces attached to the Internet to implement a...

Process allocation is important for fault-tolerant multi-computer systems since it directly aaects the performance and dependability of the system. In this paper , we consider load-balancing process allocation for fault-tolerant systems that balances the load before as well as after faults start to degrade the performance of the system. We show two schemes to tolerate multiple faults in the pas...

A word processor has become one of essential devices used in offices. Document files created by using a word processor are generally preserved on a floppy disk 01' floppy disks for referencE's. Nevertheless, the files stored on a floppy disk art' occasionally lost due to human errors. the life of the floppy disk and a failure of hardware devices, which comprise the word processor. This is callp...

Network survivability gauges the ability of a network to support the committed Quality of Services (QoS) continuously in the presence of various failure scenarios. MPLS Mesh-Based network can be used to provide network survivability in case of link and node failure through predesign path protection techniques. In the Preplanned self-healing networks, we have to provision adequate spare capacity...

There are two basic approaches to allocate protection resources for fast restoration. The first allocates resources upon the arrival of each connection request; yet, it incurs significant set-up time and is often capacity-inefficient. The second approach allocates protection resources during the network configuration phase; therefore, it needs to accommodate any possible arrival pattern of conn...
