You know a lot more about networks than I gave you credit for, Bravo. Or, you have gained a good insight of many of the issues from an altitude, Bravo, anyway.
Either way, what you say is true. But you read more into my initial statements than I had intended to go into. Here's one of those instances where you are both correct in your elaboration, but at the same time maybe missed my point which was very simple, and unrequiring of the extension you so correctly gave.
"I take this you mean, among other things, that clients and servers can emit QoS bids all day long but if the intervening nodes on the path ignore the RSVP frames then the QoS will not be forthcoming."
While that's true, it hadn't entered my mind at that point.
You state/ask:
" I don't see how their "requirement" for aggressive QoS population actually affects the rest of the world. Does it?"
Yes, it does, but in inches at a time, not meters or miles. Profound, nonetheless. Take for example the original IPTel RFCs and where they have gone. They have moved over to make room for H.323 gateway and control protocols which derive from ISDN standards, not Internet Protocol standards. In the process this has had the effect of shifting any intentions of a purer form of IP Telephony to VoIP, which has now become, for the most part, tied very closely to SS7 and Advanced Information Networking or AIN at the core of the PSTN's "intelligence." No one thing has brought this about, it was subtle and done over stretches of time. This is but one example. |
