Subject: H.323/VoIP QoS
Greetings! My name is Joon Maeng. I work for VTEL Corp in USA. I've talked
several companies while I was attending ITU and IETF meetings about
an ad-hoc group to address QoS (Quality of Service) issues in TRANSPORTING
REAL-TIME TRAFFICS in the packet switched network, especially in the IP
I was very encouraged by responses from those companies. Most of them
that lack of QoS support for real-time traffics was one of major barriers
deploying H.323/VoIP products and the H.323 industry would benefit by
QoS activity group. I would like to ask if your company would be interested
the activities described in the following:
Proposed name of the group: H.323/VoIP QoS Activity Group.
Motivation: ITU defined a good conference standard, H.323, for the packet
network. IETF is actively defining QoS standards for the IP network. The
deployment of H.323/VoIP products has been slow partially due to lack of QoS
supports in current IP network. The H.323/VoIP industry shall work together
access the issues and provide solutions for the users.
Proposed charter of the group:
- Assess QoS issues in transporting real-time traffics (calls with
compared to web-access) in the IP network,
- Find the solutions to resolve issues,
- Execute solutions via various processes such as building consensus on
QoS solutions among participants,
submitting recommendations to standardization bodies if needed, and
facilitating inter-operablity testing between QoS standards and application
- and education, promotion, etc.
I would expect the final charter and the structure of the group will be
determined by the participants and their interests. I would say that
everything is open at this time except that the industry shall look at the
issues seriously for real-time traffics. I'd like to clarify that the
group is not a group to standardize the QoS. It is a group or a forum that
interested in helping and promoting the real-time QoS for H.323/VoIP
through various methods (to be determined). I plan to set up an email
reflector for the initial discussions among participants and decide the
following steps based on the discussions. Please email me (joon_maeng@
if you and your company would be interested in joining the initial talks via
email reflector. Your comments and suggestions will be greatly
