Catastrophic failures in power grid due to maloperation of traditional backup protection system (e.g. third zone of distance relays) was one of the main causes of many cascade trips. This paper assess a new wide-area backup protection system (WABPS) based on phasor measurement units (PMU), to improve third zone of distance relays to avoid its mal-operation. Based on this assessment, phasor meas...

This paper presents a survey of backup techniques for protecting file systems. These include such choices as device-based or file-based backup schemes, full vs. incremental backups, and optional data compression. Next, we discuss techniques for on-line backup (backups performed while users continue to access the file system); these techniques include file system locking and creating instantaneo...

Controllability of complex networks has been a hot topic in recent years. Real networks regarded as interdependent networks are always coupled together by multiple networks. The cascading process of interdependent networks including interdependent failure and overload failure will destroy the robustness of controllability for the whole network. Therefore, the optimization of the robustness of i...

This paper presents a new algorithm for dynamic routing of bandwidth guaranteed multicast tunnels with failure backup. The multicast routing problem arises in many contexts such as the routing of point-to-multipoint label switched paths in Multi-Protocol Label Switched (MPLS) Networks, and the provision of bandwidth guaranteed services under the “hose” model [4]. Failure backup implies that whe...

As embedded systems take more important roles at many places, it is more important for them to be able to show the evidences of system failures. Providing such evidences makes it easier to investigate the root causes of the failures and to prove the responsible parties. This paper proposes simultaneous logging and replaying of a system that enables recording evidences of system failures. The pr...

Absnocr--This paper considers the problem of dynamically establishing dependable connections ( D c ~ ~ ~ t i ~ n s ) with peci6ed failure restoration guarantees in wavelength-routed wavelength-division multiplexed (WDM) networks. We call a connection with fault tolerant requirements as a D-connection. We recommend using a pro-active approach to fault tolerance wherein a D-connection is identifl...

Fault tolerance is an important aspect of real-time computer systems, since timing constraints must not be violated. When dealing with multiprocessor systems, fault tolerance becomes an even greater requirement, since there are more components that can fail. In this paper, we present the analysis of a faulttolerant scheduling algorithm for real-time applications on multiprocessors. Our algorith...
