Reverse replication of virtual machines (rRVM) for low latency and high availability services

摘要: Virtualization supplies a straightforward approach to high availability through iterative replications of virtual machine (VM) checkpoints that encapsulate the protected services. Unfortunately, traditional VM replication solutions suffer from deficiencies in either response latency or state recovery consistency, which constrains adoption production. In this paper, we extend function secondary host be primary recipient network requests so (PVM) is retained by form packets. doing this, redesign typical consistency model and architecture for replication. Specifically, set redirection packets recording. Should fail, recorded are used recreate on host. Experiments research demonstrate simultaneously strong low our real-time fault tolerance system. We name system reverse machines (rRVM).
