Operating a communications network

Abstract: The present invention relates to operating of a communications network, wherein a set of derived events occurs in dependence on at least one primary event in said communications network, and wherein a learning method for determining the set of derived events by analyzing the at least one primary event and by predicting the set of derived events based on data comprising relations concerning network entities and/or events in said communications network is implemented to support the management of the communications network in a more efficient way.

A common network flow formulation for several civil engineering problems

Abstract: This paper discusses a common network flow problem that arises in four areas of civil engineering. The problem is one of identifying arc flows that simultaneously satisfy the circuit and node law constraints for a given network. Applications and computational procedures in the areas of elastic structural analysis, hydraulic network analysis, traffic equilibrium and construction task scheduling are described. The interpretation of decision variables and mathematical functions will vary depending on the application, but the general priblem formulation and solution technique for each application remains essentially unchanged. Analogies between the different applications may enhance the conceptual understanding and intuition of engineers working in each area.

Arrangement for evaluating network capacity, network utilization, and network efficiency in a communications network

Abstract: A network having known network parameters is evaluated based on determined network capacity, utilization, and efficiency attributes relative to different traffic constraints and routing constraints applied to the known network parameters. Each of the network capacity, utilization, and efficiency attributes have prescribed definitions based on the network parameters and relative to the different traffic constraints and routing constraints, and are determined based on linear programming computations of the respective prescribed definitions and the network parameters. The network capacity, utilization, and efficiency attributes can then be applied to computer-based optimization resources configured for determining optimum network parameters for the network.

Traffic Engineering Using OSPF Weights and Splitting Ratios

Abstract: A method is proposed to perform traffic engineering for Autonomous Systems by setting OSPF weights and distributing new metrics called node splitting ratios The quality of the traffic engineering is comparable to that achievable using MPLS The weights and splitting ratios can be calculated using linear programming techniques This potentially allows the solution of very large problems of a scale often found in an ISP backbone Furthermore changes to network topology or addition of new flows can be easily done without performing the whole optimisation procedure The method we have presented here offers the ability to perform Traffic flow optimisation without maintaining any per flow state in routers and without introducing additional protocols or packet overhead, unlike MPLS which is commonly used for Traffic Engineering

Network traffic management system

Abstract: A traffic management system includes a traffic monitor and a traffic manager. The traffic monitor monitors traffic at a reference point T of user network interface to produce traffic information for each connection established. The traffic-manager manages network traffic of the wide-area network based on the traffic information received from the traffic monitor. The traffic information is produced for each permanent virtual connection (PVC) or for each dedicated line.
