Abstract:
1. A method of estimating traffic values or intervals in a communications network, the network comprising a plurality of nodes being interconnected by links, the method comprising: obtaining traffic data through said nodes or links as input data comprising traffic measurements for said links obtained from one or more of the nodes in the network; obtaining network data relating to a network topology and network behaviour, said network data comprising end-to-end paths in the network; estimating an effect of a modification of said communications network or its behaviour by calculating traffic information between a selected first and a selected second node of said network using said input data; repeating estimating the effect of a modification for different pairs of said first and second nodes corresponding to different modifications; selecting, according to predefined criteria, one or more candidates for modifying said communications network corresponding to one or more of said modifications; and calculating an analysis of traffic values or traffic intervals for one or more of the selected candidates.
