1. Introduction
1.1 Motivation
Even if we will have much more bandwidth in the future than now, the
control of network resource utilization remains essential for the
support of applications with special demands and for the prevention
of (malicious or accidental) waste of bandwidth. Charging provides a
possibility to control utilization and sharing of network resources.
Charging in multi-service networks can be done based on the reserved
or the actual used resources. Charging on reserved resources is an
important concept since reservation usually precludes other users
from using the reserved resources. Nevertheless, if charging is
limited to reservation parameters only, the applied charge depends on
the ability of the user to give a good prediction of the expected
traffic characteristics. This can be extenuated by using a charging
scheme that is based on both the reserved and the used resources. In
order to support usage-based charging, the collection of information
about the resource reservation and utilization is required. The
collection of data about resource usage is called accounting.
