Abstract: A Data Communication Network couples a Management System to Network Elements. The Data Communication Network comprises a Gateway Network Element and a number of the Network Elements subtended by the Gateway Network Element. A method performed by the Management System comprises: a) determining the number of Network Elements that are subtended by the Gateway Network Element; b) determining a value of an interval parameter for the Network Elements based on the number of the Network Elements that are subtended by the Gateway Network Element, wherein the interval parameter is a duration over which performance data is collected by the Network Element; and c) assigning the determined value of the history control interval parameter to the Gateway Network Element and the subtended Network Elements.

Abstract: A telecommunications network arranged for controlling the flow of SNMP trap notifications from Subtended Network Elements and subtending Gateway Network Elements to a Management System, the network being provided with a Network Analyzer arranged for determining the number of Network Elements that are subtended by each Gateway Network Element, and a Notification Threshold Manager arranged for calculating a Notification Throttling Threshold (an upper limit for the rate at which a Subtended Network Element may send SNMP trap notifications to the Management System in dependence upon the number of Network Elements that are subtended by the Gateway Network Element. The Notification Throttling Threshold is transmitted to the Gateway Network Element and Subtended Network Elements by the Management System. Also disclosed is a method for controlling the flow of SNMP trap notifications in the above-described network.

Abstract: A method for prioritizing traffic within the IP protocol of a data communications network, the method comprising detecting an activity belonging to a pre-defined group of high priority activities; identifying network elements associated with the high priority activity; and prioritizing traffic from the network elements associated with the high priority activity. Also disclosed is a management system arranged to implement the above-described method, and a data communications network comprising said management system.

Abstract: A communications network has network elements and management parts and a stored model of the network. The network elements have a controllable energy consumption status represented explicitly in the stored model. Indications of the controllable energy consumption status are passed between the management parts and network elements in a format which is compatible with the format of the model, such as by extension of TMF 814. Representing such energy status information more explicitly means it can be exchanged or distributed more efficiently, and passing the indication in a format compatible with a standard format of the network model, means a discovery request can be more easily used at various different management levels, and by various different parts of the network.

The Notification Throttling Threshold is transmitted to the Gateway Network Element and Subtended Network Elements by the Management System. Also disclosed is a method for controlling the flow of SNMP trap notifications in the above-described network.
