Abstract

The current Virtual Machine (VM) live migration research mainly focuses on transferring run-time memory state of VMs, but neglects the consistency of the network state while migration. This paper designs an Efficient and Reliable VIrtual Network (ERVIN) system, which applies several techniques: Central Information management Distributed Data transmission (CIDD), layer-two network virtualization, store and replay. It guarantees that the established network connections do not interrupt during migration. The experiments show that ERVIN is efficient. The degradation time of network performance is only around 400 ms, which can almost be neglected.
