--- Sean Doran Wrote --- Yeah, I have to agree with you there. I have long been of the opinion that all these are spouted off by marketing types and ATM biggots. As far as I am concerned, a properly designed and run network makes QoS and MPLS more a hassle than a benefit.In the absence of such a document, from which anyone can build an interoperable "true" "end to end" QoS system into his or her product, I am tempted to believe that such buzzwords are weapons in a DoS attack by marketroids. TDM. What flavour would you like? SONET/SDH? PDH? "Virtual >dark fibre"?That works very well for always on type service, but in reality, these type of services are not always on. They are periodic, at best, and the time between the periods can be hours to days. Right now they ARE over TDM, but TDM is expensive to supply (payback time and all). Data services (ATM or IP) has a much better payback time. And if you can get the stat mux gain, all the better. Of course, the prices to the customer makes TDM more attractive. (Something wrong with this picture?) Well, in a voice call, if a packet is out of order, you want to drop it. Same with broadcast video. There is no need to try to pick up that bit. This is real voice and video, not talking about stuff you get with quicktime...If you're not sure that it'll be worth anything on arrival, you shouldn't send in the first place. These are all travelling across multiple-provider paths today... Not IP paths. At least not that anyone has pointed out to me. Again, I agree totally with you. Get teh apps in shape, and all will be good.The latter distributes the problem better. The former requires well-adapting, well-behaved, Internet-ready apps to subsidize the migration of apps which are not all of these, and that will not fly. (Note that even the poor CoS substitute is unnecessary for current well-adapting, well-behaved, Internet-ready apps... that's one reason they're so inexpensive.)
