Re: First draft for discussion at DVB

[Gorry Fairhurst <gorry@erg.abdn.ac.uk>]

I apologize to all on the list - this should have been sent to
all on this list. I noted it missing from the archive and have
includes it here.

This email provides the background to a submission to DVB, 
basically asking for advice, and interest in participation in
a possible future open (ietf) working group...

Martin has agreed to provide the list with feedback on this
discussion item.

Subject:        Proposed IETF BoF on IP over DVB - an explaination!

Dear All, 

After some discussions the job of introducing this topic fell on me..
here goes. 


Proposed IETF  BoF on IP over DVB - an explanation! 
------------------------------------------------------   


Background 
------------------ 

With the new direction of DVB 2.0 which has IP as a main element,
certain activities have been started within DVB. Issues with IP have
been raised and many have now
found owner groups. Some issues have not. In some cases expertise on
issues has not been available within the groups within DVB. 

At the last TM meeting a call for remaining technical issues was made
and these are to be debated at the next meeting in November, this
clearly needs to happen and
the following is in no way intended to conflict with this. 

The issue concerning the carriage of IP over DVB have also been raised
in the DVB-BSS group. 

It has been noted that DVB has forged good liaisons with various
external bodies to promote information exchange and the question has
been posed by several DVB
members about liaison with the IETF to ensure that effort is not
duplicated, expertise is available and that good visibility of issues is
achieved. 

One problem with the IETF is that it does not readily support such
liaisons except those formed by the attendees. Thus for any successful
liaison to occur it is important
that DVB members have representation within the IETF and vica versa. 

It came to light in the discussions within the DVB-IPI group that the
PILC (Performance Implications of link Characteristics) group within the
IETF had been studying
transport of IP over links such as MPEG and DVB. Several organisation
who are also DVB members were also active in the IETF and concerned
about the commercial
and technical impliciations of the convergence of DVB/MPEG and IP
networks. Mr Gorry Fairhurst of Aberdeen University (who had presented
work in this group within
the IETF)  undertook to explore how these issues could best be tackled
within both DVB and IETF. 

The question was how to get a group within the IETF that could best
discuss the issues surrounding DVB/MPEG in a similar way to those
tackling ATM, Mobile,
Bluetooth etc. 

How to Create an IETF working group 
------------------------------------------------------- 

The road to creating an IETF group starts with finding a group of people
interested in a topic. 
  
        First one needs to have an issue. 
        This needs to be discussed with an Area Director - e.g. Internet
, Applications, General, Operations, Routing, Security, Sub IP etc. 
        Sufficient interest has to be demonstrated 
        A proposal for a group  at an IETF meeting 
                - This is known as a BoF which stands for 'Birds or a
Feather' ( for those not familiar this is a saying 'Birds of a Feather
Flock Together') 
        The BoF meets - if sufficient people attend the group and a
report is generated the BoF turns into a working group (or else it
dies!). 


Current Status 
--------------------- 

Gorry has a proposal with the relevant Area Director for a BoF to be
held at the next IETF meeting in Salt Lake City (10-14 Dec 2001). He has
created a temporary email
reflector (ip-dvb@erg.abdn.ac.uk) to discuss the formation of this group
and several DVB members have subscribed. 

A decision needs to be taken soon as to:- 

        Is there enough support within DVB for such an activity? 
        Is there any opposition to this activity within DVB? 
        Is the December IETF meeting too soon or should this be
postponed to Minneapolis in March? 

There is no desire to push for an activity that will not have enough
support and therefore not achieve the status of a working group. 

Action Required 
------------------------ 

DVB members interested in this topic and capable of attending the IETF
in either December or March and interested in the proposed BoF should
contact Mr Gorry
Fairhurst gorry@erg.abdn.ac.uk and/or subscribe to the email reflector
ip-dvb@erg.abdn.ac.uk
