Interoperability for distributed overlay virtual environments

摘要

Embodiments of the invention relate to providing interoperability between hosts supporting multiple encapsulation. One embodiment includes a method that includes mapping packet encapsulation protocol type information for virtual switches. Each virtual switch is associated with one or more virtual machines (VMs). It is determined whether one or more common encapsulation protocol types exist for a first VM associated with a first virtual switch and a second VM associated with a second virtual switch based on the mapping. A common encapsulation protocol type is selected if it is determined that one or more common encapsulation protocol types exist for the first virtual switch and the second virtual switch. A packet is encapsulated for communication between the first VM and the second VM using the selected common encapsulation protocol type.

1. A method comprising:
mapping packet encapsulation protocol type information for a plurality of virtual switches, wherein each virtual switch being associated with one or more virtual machines (VMs); determining whether one or more common encapsulation protocol types exist for a first VM associated with a first virtual switch and a second VM associated with a second virtual switch based on the mapping; selecting a common encapsulation protocol type if it is determined that one or more common encapsulation protocol types exist for the first virtual switch and the second virtual switch; and encapsulating a packet for communication between the first VM and the second VM using the selected common encapsulation protocol type.
