Hi, I have been trying to convince myself how it would work if the IP-in-UDP and GUE remained as two separate UDP port numbers. I can certainly open multiple UDP sockets in an application and send and receive packets over the sockets while considering them to be "bonded" (i.e., treated as one "tunn

Getting back to our earlier discussion, IP-in-UDP and GUE are currently two half-solutions. Put them together and you get a whole solution. Keep them apart, and someone else is going to have to write a whole solution sometime down the line from now. [Lucy] GUE can support IP payload. Don't know

I confess that I have only skimmed this thread, but as far as I can see no one has mentioned OAM. If we are designing a general purpose encapsulation there really needs to be an OAM indicator so that OAM can fate share with the data that it is monitoring. I don't think it is a factor in this disc
