11th NMRG Meeting in Osnabrück
The 11th NMRG meeting will take place in Osnabrück (Germany) on
September 15-16 2002, the week after the RIPE 43 meeting in Rhodes,
Greece. The meeting will start at 10:00 am on September 15th.
The chair of this meeting is Aiko
Pras. The local host of this meeting is the University of
Osnabrück. Our contact is Jürgen
The meeting will be held in the University of Osnabrück. The meeting
room (11/217) is located on the second floor in the main wing of the
Schloß Osnabrück (which was build in 1668).
Below is a snapshot taken from the online interactive map
of Osnabrück which shows some important locations. The Schloß is
in the center of the map and the main train station is close to the
right border where the train lines cross.
Those close by in Europe should probably just jump into the train to
reach Osnabrück. For those who need to fly in, you have the following
options to choose from:
Osnabrück has a small international airport called Münster/Osnabrück
(FMO). International here
means more or less European. If you want to reach Osnabrück from
somewhere in Europe by plane, this might be the best choice. There are
shuttle busses between the city and the airport which probably take 30
The second option is to fly to Amsterdam (AMS) and to take the train from
Amsterdam to Osnabrück. There are some direct trains which take 3
hours. The direct trains leave Amsterdam airport at 07:54, 09:54,
13:54, 17:54. Trains back to the airport leave Osnabrück main station
at 08:54, 10:54, 14:54, 18:54. There are also some additional
non-direct trains which however usually take 4 hours. When going back
to the airport, please plan for some additional time at the airport
since trains are not always on time. The oneway price is in the range
of 35 Euro (according to the German railways - the exact price might
depend a bit on where you actually buy the ticket).
The third option is to fly to Frankfurt (FRA) and to take the train
from Franfurt to Osnabrück. There are hourly trains during the daytime
which take about 4 hours. The oneway price is in the range of 65 Euro
one trip. For more details, visit the
web pages of the German railways.
There are a number of hotels in Osnabrück to choose from. There is a
list of hotels
in Osnabrück which includes price indications and some nice
photographs. However, this list only seems to be available in
German. Prices usually include breakfast.
In general, everything in the city is in walking distance. There are
bus stops close to all these hotels in case you need to catch one.
There is a central service to book hotels in Osnbrück. You can reach
this service by calling +49 541 95111-95 or by sending a FAX to +49 541
The meeting will focus on "web services for management". To get the
meeting more productive we will invite some experts on web services
from outside the NMRG.
Some of the questions that will be discussed at the meeting are:
- What are the fundamental reasons to use web-services technology.
How does this technology relate to other XML based technologies
- Should we consider SOAP /WSDL as just another mechanism to
transport management data, or will it have some impact on our
current manager-agent architecture? Particular questions are how
to deal with notifications and how to relate distributed
- Will web services technology replace SNMP technology, or will
they live in parallel? Sub-questions: will web service technology
be equally suited for element, network and service management?
Will it be useful for monitoring as well as configuration?
- How to deal with security, in particular authentication and
authorization, in web services. Is there stable technology for
this, or will it remain a battlefield for many years
(see MS-Passport versus Liberty Alliance)
- Will UDDI, which is often presented as one of the core technologies
of web services, also play a role in case of management?
- What are the implementation consequences of web services. What
is the processing /network load (compared to SNMP). How easy is
it to develop web services for management. How easy is it to build
management applications that use these services? What tools are
available to implement web services and applications?
Would it be possible to use the same tools to develop CLI
and web services?
Note that this is not the final meeting agenda; proposals for
additions or modifications are welcome and should be directed to
