PERFORMANCE ANALYSIS OF TRANSPORT PROTOCOL DURING LIVE MIGRATION OF VIRTUAL MACHINES

The Physical servers used in IT are under-utilized. The better utilization of these servers can be achieved using virtualization technology. Virtualization techniques create multiple partitions which are isolated with each other called virtual machines. Each virtual machine (guest) runs their own operating system. The resource allocated for these VMs may fail to execute an application because of resource conflict or un availability of resources. This motivates towards live migration of virtual machines. The live migration copies the running VM from source host to destination host seamlessly using TCP as transport protocol.This paper evaluates performance of TCP in live migration of KVM based virtual machines. The flexibility in UDP which drives the concentration can also be used for this migration. Keywords— Virtualization, Virtual Machines, Live Migration, Transport Protocol, Performance Analysis.
