Boot: Process by which the FPGA selectively reprograms and reloads its bitstream from an attached external memory. Safe update: Field updating bitstream storage with a new bitstream in such a manner to prevent any failure due to a failure in the update process. This is accomplished with the enhanced Multi

Automated failure recovery and debugging are two common methods of reducing the impact of failures. This paper proposes an integration of the two methods in a system for helping designers tune failure recovery and debug a plan knowledge base. The system will collect information about failures

alternative to conventional asynchronous communication protocols. The facility also ensures that the processes belonging to a fault-tolerant process group will observe consistent orderings of events affecting the group as a whole, including process failures, recoveries, migration, and dynamic changes to group

Many reliable distributed systems are consensusbased and typically operate under two modes: a fast normal mode in failure-free synchronous periods, and a slower recovery mode following asynchrony and failures. A lot of work has been devoted to optimize the normal mode, but little has focused

In this paper, we present two novel disk failure recovery methods that utilize the inherent characteristics of video streams for efficient recovery. Whereas the first method exploits the inherent redundancy in video streams (rather than error-correcting codes) to approximately reconstruct data

, it would need to know how to recover from failures or when to ask a human for help. This paper, presents a novel shared autonomy behavioral executive to addresses these issues. We demonstrate how this executive combines generalized logic based recovery and human intervention to achieve continuous failure

, we focus on techniques for automatically re-covering from functional failures. We aim to exploit the in-trinsic redundancy of many complex software systems that can produce the same results in several ways. We are inves-tigating techniques that, in case of failure, look for execution sequences

A number of strategies exist for the recovery from execution-time plan failures. One dimension in which these strategies differ is the degree of dependence on the reliability and availability of the planner’s knowledge. The best strategy, however, may be dependent on a number of considerations

This thesis sets out to gauge the strength of single tree based multicast video streaming systems in the presence of network failures. We have implemented failure recovery and improved multicast capabilities for the QStream video streaming system. Nodes in a multicast tree exchange small size

endto-end latencies and similar failure recovery properties. More importantly, it is able to achieve these results by using orders of magnitude lower control traffic. Finally, we present results from our wide-area testbed in which we experimented with 32-100 member groups distributed over 8 different
