This paper describes an application of FRL to the monitoring of a large computer network. The design utilizes frame models for the network domain and a general graphics system, and a method for coupling the two domains by analogy creation and maintenance. We also explore the use of heuristics to control the selection of viewable descriptions, at their various abstraction levels and sizes. An ul...

Ourmon is an open-source network management and anomaly detection system that has been developed over a period of several years at Portland State University. Ourmon monitors a target network both to highlight abnormal network traffic and measure normal traffic loads. In this paper, we describe the features and performance characteristics of Ourmon. Ourmon features include a novel mechanism for ...

This paper proposes a flexible network monitoring overlay which resorts to cooperative interaction among measurement points to monitor the quality of network services. The proposed overlay model, which relies on the definition of representative measurement points, the avoidance of measurement redundancy and a simple measurement methodology as main design goals, is able to articulate intraand in...

state estimation is the foundation of any control and decision making in power networks. the first requirement for a secure network is a precise and safe state estimator in order to make decisions based on accurate knowledge of the network status. this paper introduces a new estimator which is able to detect bad data with few calculations without need for repetitions and estimation residual cal...

Sonification systems, in which data are represented through sound, have the potential to be useful in a number of network-security monitoring applications in Security Operations Centres (SOCs). Security analysts working in SOCs generally monitor networks using a combination of anomaly-detection techniques, Intrusion Detection Systems and data presented in visual and text-based forms. In the las...

Software defined networking (SDN) is rapidly evolving technology which provides a suitable environment for easily applying efficient monitoring policies on the networks. SDN provides a centralized control of the whole network from which monitoring of network traffic and resources can be done with ease. SDN promises to drastically simplify network monitoring and management and also enable rapid ...

The literature on monitoring of cross-organizational processes, executed within business networks, considers monitoring only in the network formation phase, since network establishment determines what can be monitored during process execution. In particular, the impact of evolution in such networks on monitoring is not considered. When a business network evolves, e.g. contracts are introduced, ...

This document describes the trends in network monitoring technology and the requirements of emerging network monitoring applications, and outlines challenges and potential directions for next generation monitoring systems. We also discuss our experiences in designing the SCAMPI monitoring platform.

Network Traffic monitoring describes the use of a system that constantly monitors a computer network for slow or failing components and that notifies the network administrator in case of outages. Network traffic measurement is the process of measuring the amount and type of traffic on a particular network. This is especially important with regard to effective bandwidth management. Network traff...
