Abstract

The Cloud Computing is the most popular topic at present that allows creating their services on a virtual network environment. The migration mechanism was proposed to provide services, computing jobs and resources moved from a virtual environment to another virtual environment, and service providers can fit out their logic network architectures to offer services for user requirements. In the paper, the migration mechanisms were classified into host migration, resource migration, and network migration. The network migration mechanism can move the set of services and resources from a set of virtual/real machines to another set of virtual/real machines and reconfigure the network configuration automatically based on the migrated network environment. To achieve this, the proposed mechanism is implemented based on Open vSwitch and XEN, and integrates the existing network protocols. In our experimental results, we confirm that the proposed mechanism can provide live
