ROUTING OPTIMIZATION FOR VIRTUAL MACHINE MIGRATION BETWEEN GEOGRAPHICALLY REMOTE DATA CENTERS

摘要

A system and associated method for optimizing routing of data traffic for a host virtual machine. The host virtual machine communicates with an Internet Protocol (IP) network via a default gateway of a source site prior to migration. A migration service process migrates the host virtual machine from the source site to a target site, which is geographically remote from the source site and consequently changes routing efficiency of the data traffic between the host virtual machine and the IP network. The migration service process reconfigures routing parameters of the migrated host virtual machine for data traffic going out to the IP network from the host virtual machine. The migration service process examines the IP network configurability and subsequently reconfigures the IP network for inbound data traffic coming into the migrated host virtual machine from the IP network when available.
