Using UDP-Lite would be fine. I'm not sure how a transition to UDP with no checksum would help the transport concerns with mis-delivery, etc. Gorry Margaret Wasserman wrote: I had a thought on the use of zero UDP checksums in IPv6... What if we allowed the use of zero checksums for UDP as a

Dave, Thanks for sending the slides our way. When I find time later in the day, I will respond to text in the slides. If you are in Hiroshima, if you can find me, we can certainly talk as well.I will be presenting/supporting our IPv6 CPE Rtr document in v6ops at this IETF which is one goo

Thought on IPv6 Zero UDP Checksums

2009-11-08 Thread Margaret Wasserman
I had a thought on the use of zero UDP checksums in IPv6... What if we allowed the use of zero checksums for UDP as a _negotiated option_ in IETF tunneling protocols? Those protocols could default to the use of UDP Lite (or UDP with non-zero checksums if their designers prefer) and negoti
