In the following a short description of a public domain database called
QLD is given. The history of the database which now has more than 5000
entries is briefly described.

The database is now maintained by a working group of the
ITG (Fachgruppe 1.2.1 Verkehrstheorie der ITG (Informationstechnische
Gesellschaft)).  Both authors are members of this working group.


Introduction

QLD is a literature database for queueing and telecommunication literature.
There are now over 5000 entries in QLD.                                  
Most of the documents refered to in this literature database
are concerned with the performance analysis of telecommunication systems.


History

QLD is currently a national German initiative. It emerged from a
database started in 1979 at the Institute for Teleprocessing at the
Technical University of Aachen (approx. 1600 entries), a collection
from the University of Stuttgart (Institute for Communication
Switching and Data Technics, 300 entries) and some literature
collections at Philips Kommunikations Industrie AG, Nuernberg (1200
entries).

Further contributions came from the University of Wuerzburg (Institute
of Computer Science), the University of Braunschweig (Institute for
Communication Systems), Bosch Telecom Frankfurt, University of
Dortmund (Institute for Electronic Systems and Switching), University
of Saarbruecken, and School of Engineering Luebeck.

QLD contains references from the area of Traffic Engineering and
Performance Analysis of Systems and Networks published in
journals, conferences, workshops, books, etc. There are also entries
from adjoining fields such as switching and statistics.  QLD has been
designed as an English database. It contains some original language
entries, where the original language characters are used in the
template fields, e.g. Title, Journal/Publisher, Town, Remarks.
Approximately 15 percent of the entries are non-English (mainly German).


Information contained in the database

In addition to the bibliographic data some special fields were added
in the description of each document, especially the following fields:

Number of References: This number indicates how many           
citations the bibliography of the given document contains.  This is
a valuable clue when searching for further literature on a subject.
      
Language:  This field states the language of the original document.
      
Descriptors:  The main keywords describing a document are given here.
   Some examples of basic descriptors are: queueing system, queueing
   network, delay model, open queueing network, loss model, closed
   queueing network, delay loss model, Kendall's classification scheme:
   e.g. M/G/N/S, random process, arrival process, service process, Markov,  
   PH, MMPP, GMDP, MAP, DMAP, etc.                                          
   A special descriptor NIL has been used for documents that have not been
   classified yet!
                  
Remarks: 
   This field contains the abstract or main parts of the abstract.
   Some remarks of the referee can also be contained here.
                      
                      
Database Software
                      
Several ASCII-Formats of the database are available
(Export-File ADIMENS, bibtex, etc.).
This allows the use of different database systems. 
   A transformation program written in C allows to change              
automatically between different formats.
   A special filtering program can be used to assure the use of the right
coding of special national characters.
                        
                          
Outlook
                          
Several large databases will be added in the near future.  One
database e.g. contains most of the papers of the International Teletraffic  
Congress (ITC) (This database is provided by V.B. Iversen).
   Another large public domain database with about 1000                      
entries containing documents with a very similar scope as QLD will
also be added (This database is provided by H.Schulzrinne).
To simplify merging these databases, a program using pattern matching
techniques is used to avoid double entries.

The contents of the database is public domain.                         
The maintenance of this database is a joint activity of the Fachgruppe
Verkehrstheorie 1.2.1. The aim is not to have a complete database but to
supplement the professional databases and to have an easily accessible
starting point for a new line of work.  Contributions containing corrections
and additions to this database are welcome.

Acknowledgement
                                
The authors would like to thank all the contributors to QLD.      
A lot of effort has been put into QLD and we hope that
finding an important document at the right time will contribute to
some excellent future papers.
