“…In order to prevent possible failures, performance problems and to ensure reliability, availability and QoS (Quality of Service) in health systems management, it is necessary to be constantly monitoring the network's traffic [1]. For this purpose, traffic characterization is an important approach capable of describing several service profiles, such as: administrative, clinical, medical and others.…”

The practicality and convenience provided by computer networks made them indispensable, which resulted on their continuous growth both in size and complexity. Traffic monitoring became an arduous work, requiring autonomic mechanisms to describe the network's normal behavior. Thus, we introduce Digital Signature of Network Segment using Flow Analysis (DSNSF) as a mechanism to assist the networks management through traffic characterization. For this purpose, three methods belonging to different groups of algorithms are used: the statistical procedure Principal Component Analysis (PCA), the Ant Colony Optimization (ACO) metaheuristic and Holt-Winters forecasting method. We use real data for traffic characterization and evaluation of the proposed methods. The results demonstrate a good adaptability of these methods, and that generated DSNSFs can characterize the network's traffic effectively.

QoS (Quality of service) is very important for the normal functioning of currently used and newly developed network protocols, applications and services. However, providing for each protocol, applications and services the required level of QoS becomes a serious problem. To solve this problem, it is necessary to continuously monitoring and management QoS in real time. This article discusses existent methods for monitoring and managing QoS for the purpose of analyzing the problems associated with providing QoS.

“…This approach is also referred as passive probing [7]. To take advantage of the positive aspects of both methodologies, many authors propose the use of integrated solutions, where passive and active measurements are combined to achieve more scalable monitoring systems [8] [9] [10].…”

Abstract-In multiservice networks, QoS monitoring needs to be carried out in a per-class basis so that each service class measuring requirements and behavior are met and sensed properly. Facing the shortage of off-the-shelf class-based monitoring solutions, this work is focused on the development of a flexibly QoS monitoring tool oriented to multiservice networks. In this context, after discussing main QoS monitoring issues, we propose a flexible QoS monitoring Java application, totally user parameterized and supporting service differentiation. Benefiting from an edge-to-edge design perspective, this service-oriented tool is able to make a periodic evaluation of relevant QoS metrics for each service class, on an intra-domain or end-to-end path basis. Monitoring results, stored in a MySQL database, are useful to drive both online and offline traffic engineering and service management tasks.
