Building Fault-Tolerant Consistency Protocols for an Adaptive Grid Data-Sharing Service

Our approach: transparent access to data A growing number of applications make use of larger and larger amounts of distributed data. We claim that explicit management of data

Our idea is to use the abstractions described above to build fault-tolerant entities able to play the role of critical entities in consistency protocols. For instance, each home

becomes the cluster manager of the associated data group, which means that it is responsible for replicating the data block stored in that memory area.. If the provider cannot

We detail how dependencies on nodes executing no component are avoided. The resulting mechanisms allow to ensure that if a node is suspected to have failed, a restart is needed only

However, the hierarchical solution has some advantages: (1) data can be shared also among different applications thanks to persistence of grid level; (2) ASSIST does not need any

Data management in grid environments. Data management in grid en- vironments is currently a topic of major interest to the grid computing com- munity. However, as of today, no
