Assisted determination of data flows in communication/data networks
First Claim
1. A method of determining data traffic flow in a network, the method comprising:
- (a) selecting a location within the network for providing a data processing means adapted to process data pertaining to the network data traffic flow;
(b) determining the expense and/or level of data capture that would result from providing the data processing means at the selected location; and
(c) providing the data processing means at the selected location dependent on the determination in step (b) and predetermined expense and/or data capture targets.

Abstract
There is provided a method of determining data flow in a network, the method comprising: (a) selecting a location within the network for providing a data processing means adapted to process data pertaining to the network data flow; (b) determining the expense and/or level of data capture that would result from providing the data processing means at the selected location; and (c) providing the data processing means at the selected location dependent on the determination in step (b) and predetermined expense and/or data capture targets. This method can be used to select points inside the core of a network for data capture of flows routed through them in order to construct the traffic matrix of the network. This method has a number of advantages over known methods of obtaining the traffic matrix of a data network. In particular, it can be used for different use cases, maximizing the capture level for a given investment or finding the minimal investment to achieve a given capture level.

26. A method of observing data traffic in a network, the method comprising;
-
(a) determining a desired data collection result in relation to an acceptable data collection expense; and
(b) selecting a number of locations within the network for placing data collection means to obtain said desired data collection result at said acceptable data collection expense.

- 27. A data network comprising one or more inputs, outputs and routers, and a plurality of data processing means for processing data pertaining to the data flow in the network, wherein each of the data processing means is associated with a data capture value and/or an expense value, dependent on its location within the network, and wherein the number and/or locations of the data processing means are selected in accordance with predetermined expense and/or data capture targets.
