Abstract

For dynamically regulating resource splitting over a plurality of data streams competing for resources in a communications network, the resources to be split are made available in a resource pool. For each competing data stream, a resource share is taken from this resource pool and is allocated to this data stream, with the resource requirement for a data stream being dynamically aligned on the basis that, if the resource requirement has risen, a correspondingly greater resource share is allocated if possible or resources which are no longer required are returned to the resource pool. In this case, a resource share which is no longer required is returned to the resource pool if the resource share has not been required for a prescribed number of successive resource inquiries or if no new resource inquiries are received for a prescribed time period.

Claims

1. A method for dynamic regulation of resource splitting over a plurality of data streams competing for the resources in a communications network, the resources to be split being made available in a resource pool from which, for each competing data stream, a resource share is taken and is allocated to this data stream, comprising the steps of:

dynamically aligning a resource requirement for a data stream on the basis that, if the resource requirement has arisen, a correspondingly greater resource share is allocated if possible or resources which are no longer required are returned to the resource pool, where

a resource share which is no longer required is returned to the resource pool if

the resource share has not been required for a prescribed number of successive resource inquiries or if

no new resource inquiries are received for a prescribed time period.

2. The method for the dynamic regulation of resource splitting over a plurality of data streams competing for the resources in a communications network of claim 1, where the prescribed time period is proportioned such that the prescribed number of successive resource inquires could be expected therein.

3. The method for the dynamic regulation of resource splitting over a plurality of data streams competing for the resources in a communications network of claim 1, where

if the resource requirement has arisen, an allocated resource share is increased, provided that there are still other resources available in the resource pool, or otherwise

further attempts to increase a resource share are prevented until a second prescribed number of successive resource inquiries has been received.

4. The method for the dynamic regulation of resource splitting over a plurality of data streams competing for the resources in a communications network of claim 1 where

if the resource requirement has risen, an allocated resource share is increased, provided that there are still other resources available in the resource pool, or otherwise further attempts to increase a resource share are prevented until the prescribed time period has elapsed.

5. The method for the dynamic regulation of resource splitting over a plurality of data streams competing for the resources in a communications network of claim 3, where the first and second prescribed numbers of successive resource inquiries adopt a same value.

6. The method for dynamic regulation of resource splitting over a plurality of data streams competing for the resources in a communications network of claim 1, where

a time profile is ascertained for the resource requirement of the data stream and is compared with a prescribed threshold value, where

the associated resource share is increased if there are still other resources available in the resource pool,

as soon as the resource requirement reaches or exceeds the threshold value.

7. The method for the dynamic regulation of resource splitting over a plurality of data streams competing for these resources in a communications network of claim 1 where

a resource share which is no longer required is returned to the resource pool only if

upon return there is no drop below a prescribed minimum value for the resource share.

8. An apparatus for dynamic regulation of resource splitting over a plurality of data streams competing for the resources in a communications network, comprising:

a resource pool for making available resources which are to be split and from which, for each competing data stream, a resource share can be taken and can be allocated to the data stream, where

a system for dynamically aligning the resource requirement for a data stream is provided which can be used, if the resource requirement has increased, to allocate a correspondingly greater resource share if possible or to return resources which are no longer required to the resource pool, where

a resource share which is no longer required can be returned to the resource pool if

the resource share has not been required for a prescribed number of successive resource inquiries or if

no new resource inquiries are received for a prescribed time period.

9. The apparatus for the dynamic regulation of resource splitting over a plurality of data streams competing for the resources in a communications network of claim 8, where the system for dynamically aligning the resource requirement can proportion the prescribed time period such that the prescribed number of successive resource inquiries could be expected therein.

10. The apparatus for the dynamic regulation of resource splitting over a plurality of data streams competing for the resources in a communications network of claim 8, where the system for dynamically aligning the resource requirement

can increase an allocated resource share when the resource requirement has risen, provided that there are still other resources available in the resource pool, or otherwise

can prevent further attempts to increase a resource share until a second prescribed number of successive resource inquiries has been received.

11. The apparatus for the dynamic regulation of resource splitting over a plurality of data streams competing for the resources in a communications network of claim 8 where the system for dynamically aligning the resource requirement

can increase an allocated resource share when the resource requirement has risen, provided that there are still other resources available in the resource pool, or otherwise

can prevent further attempts to increase a resource share until a prescribed time period has elapsed.

12. The apparatus for the dynamic regulation of resource splitting over a plurality of data streams competing for the resources in a communications network of claim 8, where the system for dynamically aligning the resource requirement

can ascertain a time profile for the resource requirement of the data stream and can compare it with a prescribed threshold value, where

the allocated resource share can be increased if there are still other resources available in the resource pool

as soon as the resource requirement reaches or exceeds the threshold value.
