All, I was on jury duty yesterday so I wasn't able to fully engage. I agree that we are close to resolving issues and I will produce an updated draft that addresses IESG review comments, along with one change requested by IANA. I also need to respond to Ben's last email. My proposal, modulo Ben's comments, is to add the following to the draft: - Emphasizing that the mechanism only works when one of the following is true: - Agents only handle a single DRMP application. - All Diameter applications that support DRMP used in a Diameter network must have consistent and synchronized priority definitions. I'll add some words around what is meant by consistent and synchronized. - Strengthening wording indicating that this mechanism is designed to work in trusted environments. This includes recommending stripping or modifying priority settings for requests received from untrusted sources. The determination of what is a trusted and untrusted source would be out of the scope of the DRMP draft. - Adding the other updates that have been agreed to as part of this review cycle. This leaves as future work, should there be a need, the handling multiple "priority schemes" within a single network. This is a very hard problem and not a use case that is currently needed by existing users of Diameter. I'll wait for feedback, especially from the Dime working group, before I start updating the document. Regards, Steve On 5/5/16 9:39 AM, Stephen Farrell wrote: > Great.
