Patent ID: 6940871

Claim:
A method for reserving transmission capacities and for selecting requests for data streams of different bandwidths to be transmitted in digital data transmission networks having a maximum transmission rate, the method comprising the steps of: making available a particular transmission capacity which is less than or equal to the maximum transmission rate; reserving particular data transmission rates for particular bandwidths or bandwidth groups; establishing threshold values for each of the particular bandwidths or bandwidth groups; effecting a loading of a data transmission network with respect to the particular bandwidths or bandwidth groups; canceling a reservation of data transmission rates for the particular bandwidth or bandwidth group when a loading of the threshold value of the particular bandwidth or bandwidth group is exceeded; and accepting a request for transmitting data having the particular bandwidth or bandwidth group only if an unoccupied data transmission capacity then available can still meet all reservations of all remaining bandwidths or bandwidth groups with uncancelled reservations even after the request has been accepted.
