A Mobility-Oriented Scheme for Virtual Machine Migration in Cloud Data Center Network

Being a key computing element in cloud data center, virtual machines should be able to migrate from one location to another to meet the requirements of the cloud users and the defined policies of the cloud computing system. The mobility is an important issue when a virtual machine migrates across IP subnets. This paper focuses on the mobility management in cloud computing systems, and proposes a mobility-oriented cloud data center network architecture based on the identity/locator decoupling method of the mobility-driven networks. In cloud data center network, a mobile node refers to a virtual machine, and the mobility behavior mainly refers to virtual machine migration. In the proposed architecture, a virtual machine could implement live migration between IP subnets without service interruption. The evaluation shows that the proposed scheme can solve mobility issues effectively in virtual machine migration among IP subnets.
