Management system and method for configuring a network for transferring data

A management system for configuring a network path of a network for transferring an individual data flow end-to-end from a source device to a destination device, said network path comprising at least one network device susceptible of network congestion and arranged for storing at least a part of said individual data flow, said management system comprising a traffic management module arranged for determining at least one possible path for transferring said individual data flow end-to-end from said source device to said destination device, said individual data flow having been previously classified according to a footprint measure of said individual data flow, said footprint measure being indicative of a possible difference between the total amount of incoming data and the total amount of outgoing data in said at least one network device on a network path over a time interval having a duration of one or more time units, whereby said time unit is so chosen that individual data units of the individual data flow are distinguishable at byte level by said network device, and the management system further arranged for configuring said at least one network path according to said footprint measure.
