DBRpc: a highly adaptable protocol for reliable DSM systems

This paper evaluates the Dynamic Boundary Restricted protocol with phase-checking (DBRpc). DBRpc is a highly-adaptable extension of DBR that can respond to changes in the network environment and application workload. DBRpc is suitable for reliable shared memory systems that require rapid and complete response to site failures and phase changes. In this paper, we compare DBRpc with traditional protocols as well as variants of the BR/DBR class of protocols. We find that DBRpc offers unequaled adaptability and availability while having competitive operation costs.
