Video and Voice Over IP QoS Working Group
Scope of Work: The Video and Voice
Over IP QoS Working Group (hereafter QoS WG), will
develop best practices for traffic marking and publish
those best practices as standards for the ViDeNet
community. It is expected that at a minimum the QoS
WG will develop a Differentiated Services Code Point
value for diffserv. Beyond diffserv, the QoS WG may
develop similar guidelines for related QoS efforts
such as RSVP or 802.1p. It is not a charge of the
QoS WG to implement these QoS mechanisms on physical
networks but rather to communicate to network operators
the traffic marking guidelines developed for ViDeNet.
However, the WG should prototype the recommended solution
and document the results of the prototyping effort.
It is expected that the QoS WG will actively encourage
ViDeNet Zone Administrators to adopt and implement
the QoS guidelines to achieve packet marking for their
endpoints. Further, it is a goal of the group to interface
actively with related industry organizations and standards
bodies to build consensus for these guidelines, with
the goal of moving toward more broad recognition and
adoption of the guidelines. In particular, the QoS
WG will coordinate efforts with the H.323 Forum, IANA,
Internet2 VoIP WG, IMTC and ITU-T Study Group 16.
It is felt that the ViDeNet community is sufficiently
large and coherent to represent a large scale QoS-enabled
application that can serve as a meaningful test case
for real world QoS policy and enforcement study.
Working Group Chair: Tyler
Miller Johnson, University of North Carolina at
Chapel Hill
Team Members and Liaison Responsibilities:
Phil Coolick, Penn
State University (co-Chair)
Internet2 Liaison
IMTC Liaison
H.323 Forum Liaison
Membership Guidelines: Project team
members are appointed by the Working Group Chair.
This Working Group is time limited and focused on
reaching the goals stated within the Scope of Work
by the end of calendar year 2003. The Working Group
Chair will review project status at the end of calendar
year 2003 and determine if an extension of the work
period is required. If there is sufficient interest,
a follow-on effort may be undertaken to explore implementations.
