Generic Network Virtualization Encapsulation (GENEVE)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Geneve is designed to recognize and accommodate changing capabilities and
needs of different devices in network virtualization. It provides a
framework for tunneling rather than being prescriptive about the entire
system. Geneve defines the content of the metadata flexibly that is added
during encapsulation and tries to adapt to various virtualization scenarios.
It uses UDP as its transport protocol and is dynamic in size using extensible
option headers. Geneve supports unicast, multicast, and broadcast.
