Enhancing TCP Throughput of Highly Available Virtual Machines via Speculative Communication

Checkpoint-recovery based Virtual Machine (VM) replication is an attractive technique for accommodating VM installations with high-availability. It provides seamless failover for the entire soft-ware stack executed in the VM regardless the application or the underlying Operating System (OS), it runs on commodity hardware, and it is inherently capable of dealing with shared memory non-determinism of Symmetric Multi-Processing (SMP) configurations. There have been several studies aiming at alleviating the overhead of replication, however, due to consistency requirements; network performance of the basic replication mechanism remains extremely poor.
