Abstract
The strong increase of the whole internet community and the ongoing
quick growth of data rates available for end-users has led to an
enhanced demand for accessing various kinds of information. Among
others, the demand for miscellaneous information and entertainment
documents provided in different multimedia formats increases
permanently. To accommodate these demands more and more service
providers are placing various kinds of multimedia documents online on
the web at the users' disposal. These documents can be continuous
media like audio/video streams as well as text, pictures, or mixtures
of them. They are made available either for commercial or educational
use or simply for informational purposes.
In order to transmit continuous media streams with sufficiently good
quality, a certain quality-of-service (QoS) has to be guaranteed for
these streams. Basically, two common possibilities exist in order to
guarantee the service quality as required by the users of a network:
either, one can use resource reservation or, alternatively, one
could rely on priorization combined with admission control}.
In this paper we present a possible architecture for a system storing
multimedia documents at different stations. In order to provide the
required QoS to each stream within the internal network, a system for
resource management based on resource reservation is introduced. The
parameterization of the resource management and its impacts on the
system's communication behavior is investigated, whereby different
aspects of quality appraisal attract our interest. Thus, both aspects
from the operator's angle as well as the influences of trimmed QoS
from the user's point of view are investigated. For this purpose we
present benchmarks like PSNR oriented evaluations, reflecting viewer
perceived quality for video streams.
The main goal of this work is to highlight different aspects of our
resource management approach for real-time streams within a local
network, considering the architecture of a multimedia document server
as an application relevant example. Important for practical
application are the procedures to adjust the parameters of such a
system. Therefor, by means of several series of experiments we point
out correlations between parameterization and the supply of either
operator's or user's needs.
