Please find attached an annotated copy of the GDDI document. The quality of the RFP has increased substantially and it is almost good to go. That is good news. Unfortunately I did not receive any advanced copies, as discussed after the last meeting, maybe something went wrong with email.

The only concern I have is your continuous request of a “session- and connection-less” communication. I really URGE you to remove this from the RFP and leave the decision to the submitters. The idea that session- and connection-less transfers are faster is just a long-lasting and persistent illusion.

I really URGE you to remove this from 6.2 and rephrase requirement Actually, your Discussion Issue 6.7.4 contains *EXACTLY* the right idea, which re-phrased should replace requirement Trust in the submitters to make the right technology decision, and do not force them to work with something which actually doesn’t work in reality.

[ in case you question my competence in network technology, in my time at Digital Equipment Corporate Research, I was in charge of real-time communication research, and have implemented complete network stacks for multiple operating systems. ]

Feel free to contact me if you have questions.

Kind regards,
