Re: [dispatch] Charter proposal for Q4S WG ( formerly Q-HTTP) Version 1

I am a little bit confused by the combination  of 
        1. Protocol design to be used in interactive applications 
(including
      virtualized videogames,and interative-video applications)
  and
    3. Optimizing for low bit rates (typlically below 2.4 kbps)

I do not know many video games that work effectively at 2.4 kbps.

Am I missing something?

[dispatch] Charter proposal for Q4S WG ( formerly Q-HTTP) Version 1

Hi everybody, 

Here is the charter proposal for Q4S ( Quality for service) WG. This WG 
will include the achieved works with  "Q-HTTP"

Thanks for your comments

Description of Working group
============================

   Problem Statement:

   The QoS over Internet is a hot issue today. Current QoS handling
   mechanisms used in  modern network transport layers (MPLS, RSVP, 
   Diffserv,Traffic Engineering) do not provide  themselves a 
   QoS-on-demand end-to-end solution and existing adaptative 
   solutions based on In-band Control protocols (such as RTCP) 
   are very difficult to combine with any other protocols for which 
   they have not been designed for.

   Four Network Parameters comprises the QoS at application level:
   Bandwidth, packet-loss, latency and Jitter.

   Interactive-video applications define flows in both directions. 
   Different applications require different constraints (in terms of 
   latency, jitter, packet loss) in one or both directions and 
   different responsiveness. The proposed solution must be an 
   effective out-of-band application level protocol capable of 
   reacting when any of these constraints are violated. Such protocol 
   must trigger adaptive solutions and/or QoS network profile changes.

   Currently content providers are only able to provide services based 
   on adaptative methods or last-mille deployments which prefer 
   dedicated network resources (vs. Internet), and therefore, restricts 
   the subscriber population and increases the costs.

   Objetives:

   The goal of this working group is to define a 
   QoS application-level  standard protocol optimized for its use over 
   the internet that may be widely implemented and easily managed
   by application developers and service providers.

   The core technical considerations for such protocol include, but 
   are not necessarily limited to, the following:

   1. Protocol design to be used in interactive applications (including
      virtualized videogames,and interative-video applications)

   2. Ensuring interoperability with all existing transport protocols

   3. Optimizing for low bit rates (typlically below 2.4 kbps)

   4. To ensure a feasible practical implementation based on 
      policy servers and interoperability between service providers

   Deliverables:

   1. Specification of protocol that meets the requirements in the 
      form of an Internet-Draft that defines the negotiation of QoS
      parameters, the measurement process and alert mechanisms.

   2. Dimensioning rules and performance analysis

   3. A set of technical requirements for a practical
      implementation which may include adaptative solutions and/or
      QoS profile modification.

Goals and Milestiones
=====================

Nov 2010    Submit Internet-Draft as a proposed standard for QoS 
             application-level protocol

             Proposed charter for Q4S WG

             Informational document with rules for dimensioning 
             and performance analysis

             Specification of architecture document for implementation
