چکیده

In this paper we report on an ongoing statistical analysis of actual CCSN traffic data. The data consist of approximately 170 million signaling messages collected from a variety of different working CCS subnetworks. The key findings from our analysis concern: (1) the characteristics of both the telephone call arrival process and the signaling message arrival process, (2) the tail behavior of the call holding time distribution, and (3) the observed performance of the CCSN with respect to a variety of performance and reliability measurements.

Analyzing Telecommunications Traffic Data from Working Common Channel Signaling Subnetworks

Current and emerging telecommunications services are strongly dependent upon the Common Channel Signaling Network (CCSN). Regulatory rulings have accelerated the trend towards increased deployment, utilization, and connectivity of CCSNs in the U.S. In this environment, engineering issues concerning the performance, evolution, and reliability of the CCSN are important. Accurate information about...

Traffic Self-Similarity

Statistical analysis of high-resolution traffic measurements from a wide range of working packet networks (e.g., Ethernet LANs, WANs, CCSN/SS7, ISDN and VBR video over ATM) have convincingly shown the presence of fractal or self-similar properties in both local area and wide area traffic traces [2, 3, 5, 15, 19]. That means that similar statistical patterns may occur over different time scales ...

SS7 Network Management Using Link Monitors

The disruption and loss of SS7 signalling networks during the summer of 1991 in North America by the “brown outs” and the resultant loss of services, revenue and customers, has focused the minds of many Telcos to put management systems in place to ensure network robustness. Their primary purpose being to identify problem trends earlier and speed up restoration of failed signalling components. W...

Performance analysis of SS7 congestion controls under sustained overload

4ongestion controls are a key factor in achieving the robust performance required of common channel signaling (CCS) networks in the face of partial network failures and extreme traffic loads, especially as networks become large and carry high traffic volume. The CCITT recommendations define a number of types of congestion control, and the parameters of the controls must be well set in order to ...

PERTS: An interactive system for finding and describing connections between large sets of related time series

In this paper we describe Pattern Exploration of Related Time Series (PERTS) an interactive visualization system for grouping and comparing large sets of related time series. Although PERTS is useful for investigating time series in many domains, including finance and network traffic analysis, it was designed with a primary focus on interpreting data recorded from sets of hundreds to thousands ...
