Abstract:
1. An end-to-end parameter measurement management system for a network management system of a packet-oriented communications network including a multiplicity of peripheral pieces of equipment, each comprising: traffic analysis means for determining representative values of selected received traffic parameters as a function of one or more selected traffic filters and sending the values as notifications to the network management system to determine measurements of the selected parameters; control means for supplying each selected traffic filter to the traffic analysis means; and processing means for adding a selected filter identifier to each notification generated by the traffic analysis means following a traffic analysis corresponding to the selected filter, and before each notification is sent to the network management system; and wherein said parameter measurement management system includes: calculation means for deriving parameter measurements from the representative values of said parameters contained in the notifications received from an ingress piece of peripheral equipment and an egress piece of peripheral equipment; management means for sending selected filter definitions associated with the selected filter identifiers to selected pieces of peripheral equipment; and correlation means for correlating each notification including the selected filter identifier received from the ingress piece of peripheral equipment with a selected set of egress notifications received from the egress piece of peripheral equipment which each egress notification includes a filter identifier having one or more relationship links with said selected filter identifier so that said calculation means derives parameter measurements from the representative values contained in said correlated notifications.
