Geneve
GENEVE (Generic Network Virtualization Encapsulation) GENEVE encapsulated packets are designed to be transmitted via standard networking equipment. Packets are sent from one tunnel endpoint to one or more tunnel endpoints using either unicast or multicast addressing. Applications generate identical IP packets as if they were communicating via hardware switches and routers. The destination IP address included in the packet is significant only within the cloud tenant's virtual network. The tunnel endpoint then encapsulates the end-user IP packet in the GENEVE header, adding the tunnel identifier specifying the tenant's virtual network followed by any options. The header consists of fields specifying that it is a GENEVE packet, the overall length of the options if any, the tunnel identifier and the series of options. The completed packet is then transmitted to the destination endpoint in a standard UDP packet which is supported via IPv4 and IPv6. The receiving tunnel endpoint st
