Summary:
We are investigating an edge cloud architecture to achieve the flexible management and operation of the edge functions in a network. For developing an edge cloud, a scheme in which the edge functions are virtualized is effective. The virtualized edge function is achieved by carrying the edge function in a virtual machine (VM), and the VM live migration technology is used for relocating the VMs without disrupting services. Electrical power saving and efficient use of equipment are attained by using this technology for the resource management in the edge cloud. We have focused on the competition for bandwidth by user traffic and VM migration traffic that occurs when VMs are migrated in case that user traffic and VM migration traffic share a physical link. We propose a method to control bandwidth and a method to determine the order of VM migrations in order to complete all migrations while ensuring the minimum guaranteed bandwidth of user traffic. The results of evaluating the proposed methods revealed that it was possible to relocate VMs while maintaining the minimum guaranteed bandwidth of user traffic, which was not possible when the proposed methods were not used.
