My observation here is that in the PSTN there is a single common set of tools used, the information elements in SS7. The implementation of these vary: some networks use preemption (my observation is that most networks I have spoken with use preemption), and some use other techniques like call queuing, trunk queuing, and alternative call routing. That argues that it is not necessary and is perhaps inappropriate to attempt to mandate that a difference in underlying implementation forces a difference in protocol. I would go a step further. At the end of the day, carriers and vendors are being asked to implement one thing or another, with enough options to cover the needs of their various countries. In the PSTN, this was done in an international body, the SS7 protocols are used world-wide, and basically those two options are used in common implementation throughout the world. This vendor sells not only to US DoD and US DHS/NCS and their contractors. Cisco sells to many service providers that offer service in multiple countries; one of such told me that their services were offered in 70 countries. Cisco also sells to NATO, which in the final analysis means that it provides tools to military networks i roughly 90 countries. Asking for this DHS/NSC vs DoD division is a microcosm of the reality that this working group needs to address. In my humble opinion, which is of course always right (but I am too humble to say so), what we really need is a single common solution that can be interoperably deployed in preemption-ok and preemption- not-ok networks in a wide variety of countries, with configuration options to deal with the differences in implementation approach. If that is in the end not the objective, then I believe the working group should not be chartered. This ultimately hurts everyone, and is not my desire, but is the only thing that would make sense in the context. _______________________________________________ Ieprep mailing list Ieprep@ietf.org https://www1.ietf.org/mailman/listinfo/ieprep
