Abstract:
A method of managing the operation of a network, said network including a plurality of interconnected network elements (NE's) and a network management system (NMS), said method comprising the steps ofdefining for each of said NE's, an associated set of (a) possible operating states based on a selected set of measurement parameters, and (b) transitions between said states, wherein said state transitions each have associated potential causes for said NE's to move from one operating state to another operating state, thereby formulating an element behavior macro model of said NE that (a) defines the operating regions of said NE as a function of combinations of selected parameter values, and (b) describes the causes for transitions among said operating region; in each of said NE's, periodically transmitting a report including a selected set of measurement data, said state information and said transition information to said NMS; correlating transitions for multiple ones of said NE's to derive a combined model of said network; in said NMS, conducting a trend analysis based upon said combined model and said periodic reports from said NE's; and initiating management corrective actions in response to said transitions in said combined model and said trend analysis.
