8. AOB
------
1. The voluntary scribe was Thomas Telkamp, AT&T Unisource.
        (Remark: I didn't receive his minutes yet...)

------
1. Last meeting's minutes were being accepted without comment.

------
2. The open action list was as the following:


AP 1.1 (Lars-Johan Liman)       Who owns and operates current mailing-list?
        Done. -WG info-Website (@RIPE) pointed to wrong mailing-list server 
        (it was the European MBone-list @sics.se)       CLOSED

AP 1.2 (Kurt Kayser)            obtain control of Mailing-list.
        Done. Together with the RIPE-NCC the Web-site was corrected and
        the mailing-list was cleared up a bit. IMHO.. The WG-ML nevertheless
        has a slightly different name than all the other RIPE-MLs!
        (mbone-eu-op)
        which probably was the reason for confusing it with the
	'other' Mbone list.
        CLOSED

AP 1.3 (all) send details of working multicast implementations to the ML.
        CLOSED  due to lack of input and of a cross reference to a nice archive
	maintained by Graeme Wood from the MICE project:
	http://mice.ed.ac.uk/mice/archive/

AP 1.4 (Kurt Kayser)    collate response (of AP1.3) into a recommended
        list.
        CLOSED  due to the nature of closure of the last action point (AP1.3)

AP 1.5 (all)    All WG members send any information on new tools and
        vendors to the list
        CLOSED  due to lack of responses and too fast changing tools/vendor
	implementations   If a pointer is found somewhere, please
	forward  them to the Mailing-list and it will be postet on the
	WG's homepage.

AP 1.6 (Kurt Kayser)    compile outcome of AP1.5
        CLOSE   same reason as AP1.4

3. Roberto Sabatino's presentation

a revised Mbone topology for Ten-34.  Roberto Sabatino was showing
his proposals for migrating the current topology into an inproved one
due to multiple tunnel going over the same links more than once. He
basically explained where he intends to place additional
tunnel-servers from the backbone point of view (maybe he can point us
to an URI to refence his slides/talk).

----

4. Graca Cavalho, Cisco Systems
She presented a mixture of a Multicast introduction and an in-depth
view how Cisco tries to implement more scalable mechanims to route
multicast packets. This was a very well done presentation since it
gave quite a nice insight how modern routing-protocols work (PIM
sparse mode and Reverse-path-forwarding basics). The presenation had
nice examples and flowcharts how senders and receivers would reach
each other before and after initialization of the Multicast-routing
trees. - Big thanks to her again!

---- 

5. Peter Lothberg, STUPI Peter

explained the latest insight into BGP-protocol modifications that
would assist applying policy information when exchanging Multicast
traffic with other peers.  This is an essential problem which needs to
be addressed fairly soon to be able to apply previously presented
features and protocols to the Internet. He explained in all details
the mechanism how the packets need to be modified and show examples of
how they will work.

(Remark. Unfortunately this talk was quite long and extensive, and
time ran out to continue effectively in the agenda. He speeded up, but
the coffee-break basically was increasing in loudness and people
started getting nervous (smelled the fresh coffee :-))

---- 

6. This agenda point was basically left out due to time constraints,
but I might ask Peter to repeat in Stockholm this talk, since it
covers a very interesting topic.

----

7. Implementation update - MS Netshow Player v2.1 I was able to quick
show a slide of all features and make some remarks that this packages
is also available for Linux, Sun and SGI hardware.  ---- 

8. AOB - nothing to be mentioned ----

Minutes will follow after I've received them from Thomas Telkamp
(scribe)
