Abstract

With the increasing popularity of the cloud computing paradigm, data centers have become more important. Because current virtual machine live migration solutions require the live migration to take place within the same subnet without changing the IP address of the live migrated virtual machine, large Layer 2 networks are used in data centers, which creates scalability difficulties. In order to limit the size of Layer 2 networks, live migration can be done with IP address and subnet change. We implement a solution for live migration with IP address change, where the old host of a migrated virtual machine acts as a Layer 3 proxy for the virtual machine. We evaluate the performance benefits of using TCP-Freeze with this solution, where we freeze and thaw TCP connections as the virtual machine is live migrated.
