Abstract

A method intended to aid in the reservation of resources within a packet-switched communication network (CR) comprising a number N of relaying nodes (S1-S4). This method consists i), in determining for some at least of the N nodes (S1-S4) at least one resource reservation plan Pik defined by a plan identifier associated with a stream identifier and at least two ports, and ii) in memorizing for each of the N nodes (S1-S4) the various plans Pik relating to them.

Claims

1. A device for aiding resource reservation of a relaying node in a packet-switched communication network, said resource reservation for said relaying node being established following a resource reservation plan,

wherein the device for aiding resource reservation comprises:

a storage that stores information on at least two resource reservation plans associated with said relaying node, each of said at least two resource reservation plans being defined by a plan identifier characterizing a respective one of said at least one resource reservation plan to be used by said relaying node and being associated with at least one stream identifier and at least two ports of said relaying node,

a receiver for receiving a signal comprising a current reservation plan identifier characterizing a current reservation plan to be used by said relaying node among said at least two resource reservation plans,

at least one processor configured for selecting said current reservation plan among said at least two resource reservation plans, and

at least one output for transmitting instructions for said relaying node to apply said current reservation plan.

2. The device for aiding resource reservation according to claim 1, wherein said storage stores information on at least one of said at least two resource reservation plans associated with at least two streams.

3. The device for aiding resource reservation according to claim 1, wherein said at least one stream identifier can associate with different ones of said at least two ports of said relaying node based on the respective one of the at least two resource reservation plans associated with said at least one stream identifier.

4. A method for aiding resource reservation of a relaying node in a packet-switched communication network, said resource reservation for said relaying node being established following a resource reservation plan, comprising:

storing information on at least two resource reservation plans associated with said relaying node, each of said at least two resource reservation plans being defined by a plan identifier characterizing a respective one of said at least one resource reservation plan to be used by said relaying node and being associated with at least one stream identifier and at least two ports of said relaying node,

receiving a signal comprising a current reservation plan identifier characterizing a current reservation plan to be used by said relaying node among said at least two resource reservation plans,

selecting by at least one processor said current reservation plan among said at least two resource reservation plans, and

transmitting instructions for said relaying node to apply said current reservation plan.

5. The method for aiding resource reservation according to claim 4, wherein storing includes storing information on at least one of said at least two resource reservation plans associated with at least two streams.

6. The method for aiding resource reservation according to claim 4, wherein said at least one stream identifier associates with different ones of said at least two ports of said relaying node based on the respective one of the at least two resource reservation plans associated with said at least one stream identifier.

7. A relaying node in a packet-switched communication network, comprising:

a storage that stores information on at least two resource reservation plans associated with said relaying node, each of said at least two resource reservation plans being defined by a plan identifier characterizing a respective one of said at least one resource reservation plan to be used by said relaying node and being associated with at least one stream identifier and at least two ports of said relaying node,

a signal receiver for receiving a signal including a current reservation plan identifier characterizing a current reservation plan to be used by said relaying node among said at least two resource reservation plans,

at least one processor configured for selecting said current reservation plan among said at least two resource reservation plans, and

at least one output for transmitting instructions for said relaying node to apply said current reservation plan

wherein said relaying node applies said current reservation plan included in said signal.

8. The relaying node according to claim 7, wherein said signal receiver is a broadcast receiver.

9. The relaying node according to claim 7, wherein said relaying node comprises a signal transmitter for transmitting a signal comprising a modification notification of one of said resource reservation plans to the attention of a device for managing resource reservations for said packet-switched communication network.

10. The relaying node according to claim 7, wherein said relaying node applies said current reservation plan communicated with said instructions immediately after having received said signal.
