Subject: New whitepaper available re IP Router Table Management
Date: Wed, 20 Mar 2002 13:26:08 CST
Reply-To: "Information" <info@mcobject.com>
Hello,
McObject has recently published a new white paper titled
The Role of In-Memory Database Systems for Routing Table Management in
IP Routers
The paper is available for download at
http://www.mcobject.com/whitepapers.htm
Abstract: Core Internet bandwidth grows at triple the rate of CPU power, but
the promise of high-value applications can only be realized by managing much
more data traffic at the network's edge. This requires rapid evolution of
the fundamental edge infrastructure device, the IP router. To keep pace,
routing table management (RTM) software within routers must respond quickly
to changing protocol and provisioning requirements, but as demands increase,
proprietary routing table implementations encounter limitations in
scalability, extensibility, and ease of maintenance.
This paper examines the use of in-memory database systems (IMDS) within RTM
software to overcome these barriers. In addition to greater development
flexibility, IMDS technology provides built-in data integrity and fault
tolerance, while meeting data lookup and update demands needed for RTM
software to support IP routing functions. (Performance examples are provided
for Linux and Windows 2000.) This solution improves infrastructure vendors'
ability to produce new generations of routers faster and at less cost,
improving their competitive position.

Subject: Announcement: MPEG audio analysis tools
Date: Wed, 20 Mar 2002 13:26:17 CST
FYI.
We are proud to announce the latest version of our frequency-domain
audio analysis tools:
(MPEG) Maaate Version 0.2.1 and bewdy 0.2.0a
http://www.cmis.csiro.au/maaate/
(MPEG) Maaate:
==============
Maaate is a C++ frequency domain audio analysis toolkit.
http://www.cmis.csiro.au/maaate/docs/index.html
Maaate is a set of libraries supporting frequency-domain based feature
analysis. Although it currently only works on MPEG compressed audio
files in the compressed domain, the interface to plug-in other file
formats (uncompressed or compressed) exists. Maaate also contains some
30 audio feature extraction, segmentation and classification algorithms.
It's all published under the GNU GPL.
Maaate has now reached a third and quite stable development level.
Download it from: http://www.cmis.csiro.au/maaate/docs/download.html
Highlights of Maaate version 0.2.1:
- a generic frequency-domain based analysis framework
- a specific MPEG compressed (frequency) domain analysis library
- 30 analysis modules covering
* energy features (usable for loudness statistics),
* bandwidth features (usable for speech/music segmentation),
* spectral statistics (usable for sound type distinction),
* silence statistics (usable for speech/music segmentation),
* noise features (usable for explosion or crowd cheer detection),
* generic segmentation algorithms (thresholds on features) and
* some generic statistical algorithms (histogram, variance).
- extensive documentation on all modules is also available
online (http://www.cmis.csiro.au/maaate/docs/modules.html)
Bewdy :
=======
Play around with the compressed audio content of MP3 files!
http://www.cmis.csiro.au/maaate/bewdy/index.html
Bewdy is a program to visualise frequency domain audio feature analysis
and segmentation algorithms. For example, it can display the spectral
content of an MPEG audio file in the compressed domain and allows you to
play around with analysis algorithms on that data. It uses the (MPEG)
Maaate libraries for that purpose and can thus load up any analysis
module that is implemented for Maaate.
The pictures at http://www.cmis.csiro.au/maaate/snapshots.html and at
http://www.cmis.csiro.au/maaate/bewdy/docs/handbook.html show off more
of bewdy.
Download bewdy from: http://www.cmis.csiro.au/maaate/bewdy/index.html

About CSIRO audio analysis research:
====================================
Here at CSIRO, an Australian government research organisation, we
perform research into the analysis of music and sound. We create
software to unravel the structure and texture of recorded audio, and we
develop systems which make use of the information extracted. Examples of
such systems include searching for music features and indexing
soundtracks. Much of our work is available as open source software.

Description of Talk:
--------------------
The Linux Terminal Server Project (LTSP) and EtherBoot will be
discussed and demoed at this meeting. In a nutshell, LTSP provides
thin-client Linux diskless workstations. These workstations could
be built to have no local floppy, CD-ROM or hard drive, similar to
an X-terminal. Given a network card with boot ROM, all software
components of the Linux operating system would be downloaded from
a boot server and then NFS and X are used to provide access to files
and terminal sessions on one or more host computers.
LTSP version 3.0 has been recently released and it supports the
following Linux distributions: RedHat, Mandrake, SuSE, Debian,
Caldera and Conectiva. See the LTSP home page for further
information. The Linux Diskless Nodes How-To (see link below)
describes a variety of uses for diskless workstations.
EtherBoot is a software package for creating boot ROM images for
various network cards. The Boot ROM on an Ethernet Adaptor Card
(usually purchased from the manufacturer, or freely available via
EtherBoot) allows a computer to boot over the network, in a
similar manner as it would boot off of a floppy, CD-ROM or hard disk.

Speaker Biography:
------------------
Andrew Williams has been using Linux for about 8 years, and has been a
member of LTSP since December 2000. He is a project tester, and takes
takes care of the Local Audio Package and WebCam packages. Andy said
the WebCam project was the first to provide a thin client live WebCam.
Andy was part of the LTSP team exhibiting at the last Linux Expo in NYC,
and he had set up the live WebCam from the LTSP booth.
Andy is also involved with the E-Stations Project in NJ, which is
being put together by the NJ Dept of Transportation, NJ Transit, NJIT,
Mayors office and Crest Community Development Network.
Company Biography:
------------------
VarTech Solutions is a small computer consulting company located in
Newark, NJ. VarTech offers the following services: network services,
build and repair, system sales. VarTech also runs a CyberCafe type
environment, based on LTSP, which is available to the public and is
used for teaching inner-city youth the Linux Operating System.

sometimes there is a sign-in) to the elevator bank and go to the 13th
floor. When you get to the 13th floor, follow the signs leading you
to the meeting room.
The signs will lead you from the elevator, through a set of doors
(soda machine will be on your left), then past the cafeteria. After
the cafeteria, you see another "lobby" area. Walk past the cash
machines, make a left and look for a sign marking the meeting room.
Conference Room C will be on your left.
If you come very early, we may not have the signs in place yet, but
hopefully these directions will get you to the meeting room.

3. PRIOR MEETING
-------------
We need to "catch up" on some of our Thank You notes, so here goes:
a) For our November 2001 meeting:
Our thanks go to James Licata who gave us a great presentation
on Intrusion Detection and its importance as part of a
Best-Practices Approach to Security.
b) For our January 2002 meeting:
Our thanks go to Netscreen Technologies who gave us a presentation
on the principles associated with Stateful Inspection Firewalls.
Netscreen also sponsored the food service for our meeting.
c) For our February 2002 meeting:
Last month, we had a "field trip" meeting to Enterasys Networks
in midtown. Enterasys catered the meeting and provided various
tasty sandwiches, salads, fresh fruits and cookies. Andrew
Raver and Dang Nguyen gave us a very professional and technical
presentation on Wireless Technologies and Standards. As a bonus,
we were able to speak (via speaker phone) with one of Enterasys'
representatives to the Wireless Standards Committees.
d) O'Reilly has provided us with a couple of boxes of giveaways.
We have already started raffling them off. The first batch of
books to be given out were their Wireless books (given out at
our wireless meeting, of course). We also gave out O'Reilly book
catalogs as well as User Group Discount Coupons for use when
purchasing from the O'Reilly web page.
