Even more important, from my perspective, was that the IntServ work was firmly grounded in some excellent theoretical work which strongly suggests that something like the IntServ solution is about as good as you can get.
About 10 years ago, when I was at Precept Software deploying our product IP/TV, I implemented the RSVP protocol to carry IntServ requests to a peer implementation being done at Cisco. It wasn't among the easiest of tasks. I can't remember the details apart from the need to process floating point numbers in an integer-only environment. But there is something more important than the technology: A lot of "southern" countries are using or considering VoIP for their telephone structures. Yet they face a serious concern: How can they feel safe in their investment if they can not obtain assurances (I avoid the word "guarantees") of adequate levels of service so that their cross-border phone services will be usable? It strikes me that one of the needed bodies of internet governance is some sort of clearinghouse arrangement through which potential consumers (or more likely, their ISP's acting as agents) can obtain end-to-end assurances of service levels. (My mental model is sort of like Lloyds coffee house in London where people who wanted to underwrite shipping insurance would congregate.) How such assurances (again, not guarantees) might be mechanized would, I imagine, be through some combination of path and routing engineering coupled with ingress constraints to reduce the chances of edge overload. Of course, I do expect that people would have to hand over $$ (or more likely Euros) for this kind of thing. But I would also expect that it should and must be free from manipulation and unfair self-dealing on the part of the providers. --karl-- ------------------------------------------- Archives: https://www.listbox.com/member/archive/247/=now RSS Feed: https://www.listbox.com/member/archive/rss/247/ Powered by Listbox: http://www.listbox.com
