Alternative to UDP

Alternative to UDP

[Eric Dillmann]

Hi,

Today i discovered that OVH is limiting UDP rate to 6Mbit/s, i did a test by encapsulating wireguard in an ip/ip tunnel
and got 90Mbit/S. 

Is there a way to make wireguard evolve to use it's own protocol number.

That would prevent the overhead of wireguard over ipip/gre/vxlan ...

Thanks,
Regards,
Eric

Hi,

This feels like a bad idea to me - switching to a dedicated protocol would
remove a small amount of overhead, but comes with a lot of downsides, which
in my opinion outweighs the minor benefit of removing some of the overhead.

I have a strong preference for the continued use of UDP, because a large
amount of consumer networking gear can't handle destination NAT for
anything that isn't UDP or TCP. And even wth gear that can, using a
separate IP protocol would limit clients relying on destination NAT to one
client machine per public IP.

Cheers,
Steve

Dear Eric,

I strongly second Steve's opinion here: if you want this, make it
option-defined, and definitely not the default option.
The case study to look at is SCTP:
https://en.wikipedia.org/wiki/Stream_Control_Transmission_Protocol

While an interesting and useful protocol, SCTP adoption and support is
severely limited by the fact that it is an IP protocol on its own:
SCTP gets dropped in 90% of implementations doing IP packet header
operations (NAT, PCEF, Firewalls, 6to4 ...)

Hope this helps,
Best regards,
Philippe Langlois.
