Fault Recovery in Distributed Processing Loop Networks
A graph model is introduced to formalize the fault recovery process in distributed loop networks. This model is applicable to centralized as well as distributed recovery. Key fault tolerance and recovery parameters including redundancy, fault model, recovery time, and recovery strategy are characterized. Centralized recovery strategies for a given fault-tolerant loop network are presented and a...

چکیده رساله/پایان نامه : تاکنون روشهای متعددی در ارتباط با مکان یابی خطا در شبکه انتقال ارائه شده است. استفاده مستقیم از این روشها در شبکه توزیع به دلایلی همچون وجود انشعابهای متعدد، غیر یکنواختی فیدرها (خطوط کابلی، خطوط هوایی، سطح مقطع متفاوت انشعاب ها و تنه اصلی فیدر)، نامتعادلی (عدم جابجا شدگی خطوط، بارهای تکفاز و سه فاز)، ثابت نبودن بار و اندازه گیری مقادیر ولتاژ و جریان فقط در ابتدای...
1 Proactive Fault - Recovery in Distributed Systems
Supporting both real-time and fault-tolerance properties in systems is challenging because real-time systems require predictable end-to-end schedules and bounded temporal behavior in order to meet task deadlines. However, system failures, which are typically unanticipated events, can disrupt the predefined real-time schedule and result in missed task deadlines. Such disruptions to the real-time...
متن کاملDistributed Recovery Block Based Fault-tolerant Multicasting
This paper presents a fault-tolerant and adaptive multicasting method that employs a modified distributed recovery block (DRB) approach. The section of a distributed system spanning between the source and destination nodes is partitioned into series of overlapping DRB groups on the multicasting paths. Each DRB group consists of three nodes: a current node and two successor nodes. The source nod...
متن کاملCache based fault recovery for distributed systems
No cache based techniques for roll forward fault re covery exist at present A split cache approach is pro posed that provides e cient support for checkpointing and roll forward fault recovery in distributed systems This approach obviates the use of discrete stable stor age or explicit synchronization among the processors Stability of the checkpoint intervals is used as a driver for real time op...
