hi Janet i like your example about the explosion :-) i have attached an image named Q-HTTP_phases.jpg for quick understanding ( for people that have asked for it) There are two ways to address an undesirable situation: "adaptative solutions" and "enhance QoS solutions" For both cases Q-HTTP could be a handy tool Regarding QoS solutions: ================== If the files about the way to avoid the explosion are so important, then these files could be downloaded using SLA , and for sure the user or the content provider will pay for that. user-----(pay per FTP with quality)---->content provider-------(pay for quality)--------> ISP user-----(pay per game with quality)---->content provider-------(pay for quality)--------> ISP user----( no pay anything)----->content provider ------( no pay for quality)----->ISP video or videogame is not more important than FTP, and FTP is not more important than video. It depends on how much the content provider or the user is willing to pay for it with QoS Regarding adaptative solutions: ================== Q-HTTP also may be used for detect packet loss and adjust FTP bitrate, or change parallel FTP for sequential FTP. Q-HTTP is a tool. The decision to take when Q-HTTP alerts is open - jose Javier ________________________________ De: Janet P Gunn [mailto:jgunn6@csc.com] Enviado el: sábado, 13 de noviembre de 2010 15:48 Para: Henry Sinnreich CC: conex@ietf.org; dispatch@ietf.org; dispatch-bounces@ietf.org; Mike Hammer (hmmr); httpstreaming; Ingemar@core3.amsl.com; Johansson S; GARCIA ARANDA, JOSE JAVIER (JOSE JAVIER); Kathy McEwen; DIAZ VIZCAINO, LUIS MIGUEL (LUIS MIGUEL); Mikael Abrahamsson Asunto: Re: [dispatch] [conex] [httpstreaming] Q-HTTP > On 11/11/10 12:43 PM, "DIAZ VIZCAINO, LUIS MIGUEL (LUIS MIGUEL)" > <luismi.diaz@alcatel-lucent.com> wrote: > > > Hi, > > Just a different approach.

Yes, everyone gets out of the way of the ambulance, because the ambulance is more important. But the real time game is NOT more important than downloading the file that contains the information on how to turn off the flow of the natural gas pipeline when there is an explosion. What you are proposing in your analogy is not that "everyone should get out of the way of the ambulance", but that "everyone should get out of the brand new Ferrari so it can race with the Maserati."
