Abstract: The current communications world is characterized by increasing number of end
user terminals, as well as the emerging convergence of different communication services with
the IP world. Thus, keeping a good network performance across all domains within a
heterogeneous network became a challenge. Accordingly, the complexity of the performance
measurement mechanism became higher and is in a real need to simplification and accuracy
to keep pace with the overwhelming growth. This paper deals with an approach of using the
signaling networks protocol analysis in assessment of networks performance including the
legacy core segment, the IP core segment, the wireless segment, as well as the application
segment. As well, the use of the technique in the early detection of security attacks is
elaborated which is based on network abnormal events detection A full analysis methodology
is proposed, using statistical algorithms and mathematical modeling of a sample of traffic
scenarios. As a conclusion, the proposed mechanism helps in simplification, quickness, and
accuracy of measurements regardless of the manufacturer proprietary applications, and nodes
architectures.
