摘要: The cloud service delivery model is driving the data center (DC) architectural towards a fully virtualized infrastructure acting as geographically distributed pools of shared resources, dynamically allocated to different services. Such scenario calls for anycast routing virtual machine (VM) migration requests in order select destination server where VMs will be migrated by taking into account actual load DC interconnections while addressing VM transfer requirements. To this purpose, management platform presented that enables dynamic connectivity setup between DCs without priori indication server, according principle. Specifically, path allocation policies are proposed proper inter-DC network path, and accordingly allow experience adequate delay performance. Using simulation approach, compared terms success rate delay-constrained well their capability limit delay.
