Abstract: With the convergence of IN and IP traditional network management
systems have been replaced by a variety of standards. New principles of
management have also emerged. Related to these changes new alternative
network management techniques are needed. There are a lot of efforts in
management protocols improvement based on advanced computer simulation
techniques. But, there is a lack in the development of fundamental theoretical
models for management architectures. To remedy the situation we develop an
analytical modelling tool for the converged network management. More
precisely, we implement a queuing model on the application layer to perform
effectively a signalling management into both parts of the converged SIP- and
IN-based network. We model this distributed management configuration as a
finite source queuing model. Furthermore, we evaluate the steady-state
performance measures such as expected waiting time and time in system, and
present numerical results providing corresponding curves for them.

1 Introduction
The convergence in telecommunication networks has raised a major challenge for
creating new management and control infrastructures. The difficulty is how to make the
solutions from a multitude of vendors to operate with diverse protocols. In order to solve
these problems, we need to develop an integrated network management platform to
monitor and control the resources in different intelligent devices, the connections and
communications of these devices, and the applications run on them. The IEEE standard
802.6 specifies that network management provide mechanisms for monitoring, control
and coordination of all managed objects within the physical and data link layer of a node.
The system management is defined as providing mechanisms for the monitoring, control
and coordination of all managed objects within open systems. System management is
effected through application layer protocol.
The network management used to be simpler and empirical when most networks were
homogeneous. The situation prevalent today, with ubiquitous heterogeneous networks,
requires more involved, standardised, ordered and acceptable ways to manage these
rapidly changing, converging and evolving networks (Narang and Mittal, 2000;
Kryvinska, 2008).
In the past, voice and data networks were separate because:
• their features and operational principles were different
• circuit-switched networks supported higher quality of voice services
