USING PHYSICAL LOCATION TO MODIFY BEHAVIOR OF A DISTRIBUTED VIRTUAL NETWORK ELEMENT

摘要

A system for network virtualization in which physical network resources in different physical contexts are configured to implement one or more distributed logical network elements, at least some of the physical network resources implementing the distributed logical network elements configured according the physical context of those network resources. The local configuration of a physical locale is a version of the logical configuration that is modified specifically for the physical locale. Such modification is based on locale identifiers that are assigned to the physical locales. Some systems use locale-specific information to modify next- hop preference. Some system use locally modified configurations to determine the placement of VMs.
