Dear All,
RIPE NCC New Projects are pleased to announce the following activities
during RIPE 42:
------------------------------------------------------------------------
--------------
* Demonstrations of Test Traffic Measurements (TTM) and Routing
Information Service (RIS):
RIS Demo
Expert help available
Wed: 10:30-11:00
Thu: 10:30-11:00
Fri: 10:30-11:00
TTM Demo
Expert help available
Thu 15:30-16:00
Fri 10:30-11:00
We will be in the Hostmaster's room, opposite the Information Desk.
----------------------------
* "Introduction to the Routing Information Service" to be held on
Monday, 29 April 2002, from 15:30 - 16:00 during the EOF session.
This tutorial will give a brief introduction on the RIS, then show how
the RIS can be used to understand and solve day-to-day operational
problems.
Speaker: Matthew Williams (RIPE NCC New Projects)
Intended Audience: Network engineers and operators with working
knowledge of BGP.

This is an auto-generated mail on Fri Apr 5 23:00:00 PST 2002
It is not checked before it leaves my workstation. However, hopefully
you will find this report interesting and will take the time to look
through this to see if you can improve the amount of aggregation you
perform.
Check http://www.employees.org/~tbates/cidr-report.html for a daily
update of this report.
NEW: Check http://www.employees.org/~tbates/cidr-report-region.html for
the regional version of this report.
NEW: Check http://www.employees.org/~tbates/autnums.html for a complete
list of autonomous system number to name mappings as used by the CIDR-Report.
The report is split into sections:
0) General Status
List the route table history for the last week, list any possibly
bogus routes seen and give some status on ASes.
1) Gains by aggregating at the origin AS level
This lists the "Top 30" players who if they decided to aggregate
their announced classful prefixes at the origin AS level could
make a significant difference in the reduction of the current
size of the Internet routing table. This calculation does not
take into account the inclusion of holes when forming an aggregate
so it is possible even larger reduction should be possible.
2) Weekly Delta
A summary of the last weeks changes in terms of withdrawn and
added routes. Please note that this is only a snapshot but does
give some indication of ASes participating in CIDR. Clearly,
it is generally a good thing to see a large amont of withdrawls.
3) Interesting aggregates
Interesting here means not an aggregate made as a set of
classful routes.
Thanks to GX Networks for giving me access to their routing tables once a
day.
Please send any comments about this report directly to CIDR Report <cidr-report(a)cisco.com>.

This is an auto-generated mail on Fri Mar 29 23:00:00 PST 2002
It is not checked before it leaves my workstation. However, hopefully
you will find this report interesting and will take the time to look
through this to see if you can improve the amount of aggregation you
perform.
Check http://www.employees.org/~tbates/cidr-report.html for a daily
update of this report.
NEW: Check http://www.employees.org/~tbates/cidr-report-region.html for
the regional version of this report.
NEW: Check http://www.employees.org/~tbates/autnums.html for a complete
list of autonomous system number to name mappings as used by the CIDR-Report.
The report is split into sections:
0) General Status
List the route table history for the last week, list any possibly
bogus routes seen and give some status on ASes.
1) Gains by aggregating at the origin AS level
This lists the "Top 30" players who if they decided to aggregate
their announced classful prefixes at the origin AS level could
make a significant difference in the reduction of the current
size of the Internet routing table. This calculation does not
take into account the inclusion of holes when forming an aggregate
so it is possible even larger reduction should be possible.
2) Weekly Delta
A summary of the last weeks changes in terms of withdrawn and
added routes. Please note that this is only a snapshot but does
give some indication of ASes participating in CIDR. Clearly,
it is generally a good thing to see a large amont of withdrawls.
3) Interesting aggregates
Interesting here means not an aggregate made as a set of
classful routes.
Thanks to GX Networks for giving me access to their routing tables once a
day.
Please send any comments about this report directly to CIDR Report <cidr-report(a)cisco.com>.
