Adaptable non-interactive video delivery is suitable for congestion problems, but what about latency? It is no possible to adapt to a large latency reducing video resolution. I refer to the "interactive video" scenario, for example a virtualized videogame. Video must be delivered to the final user quickly and final user press action controls which change the video in real-time. If final user wants to play to "Street fighter" in a videoconsole located in the cloud, it is needed a mechanism for Measuring and adjust latency, in both directions. Even with overall more bandwidth than needed, the problem persists. - Jose Javier -----Mensaje original----- De: Mark Watson [mailto:watsonm@netflix.com] Enviado el: miércoles, 10 de noviembre de 2010 5:19 Para: Kathy McEwen CC: Lars Eggert; David Singer; Ingemar Johansson S; GARCIA ARANDA, JOSE JAVIER (JOSE JAVIER); httpstreaming; dispatch@ietf.org; conex@ietf.org Asunto: Re: [httpstreaming] [dispatch] Q-HTTP Sent from my iPad On Nov 9, 2010, at 7:01 PM, "Kathy McEwen" <kathy@iridescentnetworks.com> wrote: > One problem with the voice analogy is that the sheer volume of data > traversing the web today is not driven by voice...it's video...and > it's not even a fraction of the viewing that folks are doing of > broadcast content.

QoS is expensive too. I tend to agree with the thesis below that history is telling us that avoiding scarcity in the first place is cheaper than rationing here. ...Mark > -----Original Message----- > From: httpstreaming-bounces@ietf.org > [mailto:httpstreaming-bounces@ietf.org] > On Behalf Of Lars Eggert > Sent: Tuesday, November 09, 2010 8:02 PM > To: David Singer > Cc: Ingemar Johansson S; GARCIA ARANDA, JOSE JAVIER (JOSE JAVIER); > httpstreaming; dispatch@ietf.org; conex@ietf.org > Subject: Re: [httpstreaming] [dispatch] Q-HTTP > > On 2010-11-9, at 18:31, David Singer wrote: >> It is that there are two ways to solve a real-time bandwidth need. >> One is > to reserve bandwidth, manage QoS and so on; one gets protocols and > systems like diffserv, ATM, and so on.
