Re: [httpstreaming] [dispatch] Q-HTTP

Hi Mark, 

Some people from "Universidad Politecnica de Madrid" is suggesting us some ideas for a different name:

QOSCP  (Quality Of Service Control Protocol) 
QCP (Quality Control Protocol) 
QUALITAS 

We are in brainstorming process :-) 

any other one?

Without going into the details of the proposal itself --

"Q-HTTP" is a *horrible* name. It will confuse many people -- is it a replacement for HTTP? An enhancement to HTTP? Etc.

Please change the name and proposed URI scheme ASAP; it'll make it a lot easier to socialise if it does gain traction.

Furthermore, based on this statement:

>    Q-HTTP does not establish multimedia sessions and it does not transport application data.

... the only thing it shares with HTTP is the syntax of the messages. Lots of IETF experience shows that basing new protocols on HTTP syntax isn't such a good idea; if you want an easy-to-parse format, how about JSON?

Please don't take this as criticism of the proposal itself -- I'm excited to see so many people working in this area.

Cheers,

We have a Bar BOF on HTTP streaming on Wednesday evening, Emenrald room, which aims at  building new area and working out appropriate working scope to offer more efficient transport and better QoE. One of key issues we are ready to address is QOE improvement. If you are interested, please join our discussion.

The final goal of this process is to verify that a certain application which depends on bandwidth, latency, jitter parameters, will work under current network conditions. Our idea tackles the fact that real-time services (virtualization, on line gaming, video, voice) nowadays are increasing and that in an internet (or WAN) environment propagation conditions may change with time for our connection; what works for most applications may not work for real-time ones and they should have a standard way of negotiating and verifying their requirements. Q-HTTP also provides a mechanism of account/alerting when required constraints are not met after the measurement is carried out.
