This idea sound great, Did you propose any draft? Regards.

Section 5.3 should be a separate I-D. draft-xiang-nvo3-geneve-packet-spray-00 handles putting a Layer 4 protocol (TCP or UDP) on top of Geneve by assigning new Ethertypes (0x9004/9005). A more elegant way is what I proposed last July: Due to the different types of Ethernet, Ethertypes are restricted to 0x0600 and higher; the values 00 through 05 can't appear as the first byte. (Though there actually are IEEE assignments in that range, there are none with a high byte of 00.) We can therefore modify the definition of the "Protocol Type" field in the Geneve header such that if the first byte is 00, then the second byte is the IP "protocol" value for the contained packet. That covers TCP, UDP, and all Layer 4 protocols carried inside of IPv4/IPv6.
