 | Demo of VMware's vSphere Fault Tolerance (FT) This video will demonstrate the configuration and testing of the Fault Tolerance feature in VMware's vSphere. This new feature allows you to have a hot virtual machine in standby ready to take over if the primary fails. Unlike other clustering type solutions there is no reboot of the host or restart of the application. The secondary is kept in lockstep with the primary and is in the exact state of the primary when failover occurs. 2009年05月01日再生回数 73058 |

 | A Fault Tolerant Network Architecture The Internet, in its early inception, was the result of research funded by the United States Department of Defense (DoD). Its primary goal was to have a communications medium that could withstand the destruction of numerous sites and transmission facilities without disruption of service. It only follows that fault tolerance was the focus of the effort of the initial internetwork design work. Early network researchers looked at the existing communication networks, which were primarily for the transmission of voice traffic, to determine what could be done to improve the fault tolerance level. 2011年09月26日再生回数 285 |
 | Knowledge Connectivity vs. Synchrony Requirements for Fault-Tolerant Agreeme... Google Tech Talks April, 18 2008 ABSTRACT Agreement problems are fundamental building blocks of reliable distributed systems, and the issue of designing reliable solutions that can cope with the high dynamism and self-organization nature of mobile ad-hoc and peer-to-peer networks is a very active field of current research. The core problem behind agreement problems is the consensus problem. Informally, a group of processes achieves consensus in the following sense: each process initially proposes a value and all correct processes must reach a common decision on some value that is equal to one of the proposed values. It is well known that in classical environments, in which entities behave asynchronously and where identities are known, consensus cannot be solved in the presence of even one process crash. It appears that self-organizing systems are even less favorable because the set and identity of participants are not known. In this talk, we are going to present necessary and sufficient conditions under which fault-tolerant consensus become solvable in these environments. Those conditions are related to the synchrony requirements of the environment, as well as the connectivity of the knowledge graph constructed by the nodes in order to communicate with their peers.

 | Adaptive Fault Tolerant QoS Control Algorithms for Maximizing System Lifetime of Query-Based info@thebookmyproject.com www.thebookmyproject.com Abstract Data sensing and retrieval in wireless sensor systems have a widespread application in areas such as security and surveillance monitoring, and command and control in battlefields. In query-based wireless sensor systems, a user would issue a query and expect a response to be returned within the deadline. While the use of fault tolerance mechanisms through redundancy improves query reliability in the presence of unreliable wireless communication and sensor faults, it could cause the energy of the system to be quickly depleted. Therefore, there is an inherent tradeoff between query reliability vs. energy consumption in query-based wireless sensor systems. In this paper, we develop adaptive fault tolerant quality of service (QoS) control algorithms based on hop-by-hop data delivery utilizing "source" and "path" redundancy, with the goal to satisfy application QoS requirements while prolonging the lifetime of the sensor system. We develop a mathematical model for the lifetime of the sensor system as a function of system parameters including the "source" and "path" redundancy levels utilized. We discover that there exists optimal "source" and "path" redundancy under which the lifetime of the system is maximized while satisfying application QoS requirements. Numerical data are presented and validated through extensive simulation, with physical interpretations given, to demonstrate the feasibility of our algorithm design. 2011年10月22日再生回数 420 |
