Abstract

A method of distributing a first software component to a number of nodes of a telecommunication network is described. According to the method: a first node is provided with said first software component; said first node provides to a second adjacent node information on the availability of said first software component at said first node; said second adjacent node, according to the information received from said first node, determines whether to download said first software component from said first node; a third node is provided, which is adjacent to said second node; said second node provides to said third node information on the availability of said first software component at said first node and/or at said second node; and said third node, according to the information received from said second node, determines whether to download said first software component from said second node or from said first node.

Claims

1. A method of distributing a first software component to a number of nodes of a telecommunication network, wherein:

a first node is identified among said number of nodes;

said first node is provided with said first software component;

said first node provides to a second adjacent node information on the availability of said first software component at said first node;

said second adjacent node, according to the information received from said first node, determines whether to download said first software component from said first node;

a third node is provided, which is adjacent to said second node;

said second node provides to said third node information on the availability of said first software component at said first node and/or at said second node; and

said third node, according to the information received from said second node, determines whether to download said first software component from said second node or from said first node.

2. The method according to claim 1, wherein a second software component is distributed to said third node of the network, the step of distributing said second software component comprises:

said second software component is provided to said first node;

said first node provides to a second adjacent node information on the availability of said second software component at said first node;

said second adjacent node, according to the information received from said first node, determines whether to download said second software component from said first node;

said second node provides to said third node information on the availability of said second software component at said first node and/or at said second node; and

said third node, according to the information received from said second node, determines whether to download said second software component from said second node or from said first node.

3. The method according to claim 1, wherein a fourth node, adjacent to said third node, is provided with said first software component, said second and fourth nodes provide information on the availability of said first software component at said second and fourth nodes, respectively, and said third node, according to the information received from said second and fourth nodes, determines whether to download said first software component from said second node or from said fourth node.

4. The method according to claim 3, wherein said third node determines whether to download said first software component from said second node or from said fourth node according to criteria minimizing a cost for downloading said first software component.

5. The method according to claim 3, wherein said third node determines whether to download said first software component from said second node or from said fourth node according to criteria minimizing a time for downloading said first software component.

6. The method according to claim 1, wherein the step of providing said first software component or said second software component to said first node is performed by a Network Operation Center, and wherein, said Network Operation Center is notified about the software component downloads in the nodes of the network.

7. The method according to claim 6, wherein said first node is a gateway node and it is connected to said Network Operation Center.

8. The method according to claim 7, wherein it further comprises a step of partitioning said network into a number of network partitions, each of said network partitions comprising a gateway node.

9. The method according to claim 1, wherein said information on the software component availability includes a name of said software component.

10. The method according to claim 1, wherein said information on the software component availability includes a name of a node where said software component is available.

11. The method according to claim 1, wherein said information on the software component availability includes information about software release.

12. The method according to claim 1, wherein said information on the software component availability includes information about software compatibility.

13. The method according to claim 12, wherein it further comprises a step, performed in a node, of verifying compatibility of said first software component with any other software component already installed in said node.

14. The method according to claim 1, wherein said information on the software component availability includes information about cost for downloading said software component.

15. The method according to claim 1, wherein said information on the software component availability includes information about time for downloading said software component.

16. A telecommunication network node for performing a method according to claim 1, wherein it comprises a software component list, means for updating such a software component list and means for forwarding such a software component list to at least an adjacent node and means for, upon request from said at least one adjacent node, providing such an adjacent node with one or more software components.

17. A node according to claim 16, wherein it further comprises means for receiving a software component list from an adjacent node and means for requesting a software component to said adjacent node.

18. A node according to claim 16, wherein it further comprises means for receiving a software component list from an adjacent node and means for requesting a software component to a non-adjacent node.

19. A node according to claim 17, wherein said means for requesting a software component comprise means for comparing the software component list received from an adjacent node with its software component list.

20. A node according to claim 16, wherein it further comprises means for notifying a network operation centre the receipt of a software component.

21. A telecommunication network comprising a plurality of nodes according to claim 16.
