Session level rollback recovery
نویسنده
چکیده
The problem of rollback recovery is traditionally approached using a model oriented to packet delivery. Instead, we introduce a model centered around complex sessions, and we explain why this model is more appropriate. Using this model, we extract a basic coordination scheme that is common to the three distributed activities that compose rollback recovery: checkpointing, rollback and disposal. The basic coordination scheme is refined to describe each of the three activities.

Bounding Recovery Time in Rollback-Recovery Protocol for Mobile Systems Preserving Session Guarantees
This paper addresses a problem of integrating the consistency management of session guarantees with recovery mechanisms in distributed mobile systems. To solve such a problem, rollback-recovery protocol rVsSG, preserving session guarantees is proposed. The protocol employs known rollback-recovery techniques, however, while applying them, the semantics of session guarantees is taken into account...

This paper presents rVsMR rollback-recovery protocol for distributed mobile systems, guarantying Monotonic Reads consistency model, even in case of server’s failures. The proposed protocol employs known rollback-recovery techniques, however, while applying them, the semantics of session guarantees is taken into account. Consequently, rVsMR protocol is optimized with respect to session guarantee...
متن کاملAsynchronous Optimistic Rollback Recovery Using Secure Distributed Time
In an asynchronous distributed computation, processes may fail and restart from saved state. A protocol for optimistic rollback recovery must recover the system when other processes may depend on lost states at failed processes. Previous work has used forms of partial order clocks to track potential causality. Our research addresses two crucial shortcomings: the rollback problem also involves t...
متن کاملA Generic Rollback Manager for Optimistic HLA Simulations
This paper describes the addition of an extra piece of software, a rollback manager, to implement state saving and rollback management for optimistic federates in the High Level Architecture (HLA). This mechanism uses computational reflection techniques to create a rollback manager metaobject that extends the low-level time management services provided by HLA. The main propose of the rollback m...
