Abstract

Propagating firmware updates in a peer-to-peer network including identifying, that one or more nodes in the network have firmware that is uplevel with respect to the downlevel node; broadcasting an update request requesting an update to the firmware; receiving a plurality of portions of the update, metadata describing each portion of the update received, and metadata describing the firmware installed on each of the plurality of nodes having firmware uplevel with respect to the downlevel node; determining, in dependence upon the metadata describing each portion of the update received and the metadata describing the firmware installed on each of the plurality of nodes having firmware uplevel with respect to the downlevel node, whether the portions of the update received comprise an entire update; and updating the firmware if the portions of the update received comprise the entire update.

Claims

1. A method of propagating firmware updates in a peer-to-peer network environment, the method comprising:

identifying, by a downlevel node in a peer-to-peer network, that one or more nodes in the peer-to-peer network have firmware that is uplevel with respect to the downlevel node;

broadcasting, by the downlevel node, an update request requesting an update to the firmware;

receiving, from a plurality of nodes having firmware uplevel with respect to the downlevel node, a plurality of portions of the update, metadata describing each portion of the update received, and metadata describing the firmware installed on each of the plurality of nodes having firmware uplevel with respect to the downlevel node; and

determining, in dependence upon the metadata describing each portion of the update received and the metadata describing the firmware installed on each of the plurality of nodes having firmware uplevel with respect to the downlevel node, whether the portions of the update received comprise an entire update; and

updating, by the downlevel node, the firmware if the portions of the update received comprise the entire update.

2. The method of claim 1 further comprising broadcasting again, by the downlevel node, again an update request if the portions of the update received do not comprise the entire update.

3. The method of claim 2 wherein broadcasting again an update request further comprises sending to all of the nodes of the peer-to-peer network an update request that includes an identification of the portions of the update not received in response to the previous broadcast.

4. The method of claim 1 further comprising determining, by the downlevel node in dependence upon metadata describing the firmware installed on each of the plurality of nodes having firmware uplevel with respect to the downlevel node whether one of the nodes sending a portion of the update has a corrupted image of the uplevel firmware;

and

notifying, by the downlevel node, the nodes having a corrupted image of the uplevel firmware if one of the nodes sending a portion of the update has a corrupted image of the uplevel firmware.

5. The method of claim 1 wherein identifying, by a downlevel node in the peer-to-peer network, that one or more nodes in the peer-to-peer network have firmware that is uplevel with respect to the downlevel node further comprises receiving a message broadcast from the node having firmware that is uplevel.

6. The method of claim 1 wherein identifying, by a downlevel node in the peer-to-peer network, that one or more nodes in the peer-to-peer network have firmware that is uplevel with respect to the downlevel node further comprises:

periodically broadcasting, by the downlevel node, a request for identification of firmware on other nodes in the peer-to-peer network; and

receiving, in response to the broadcast, a plurality of identifications of firmware installed on a plurality of other nodes in the peer-to-peer network.

7. The method of claim 1 wherein updating, by the downlevel node, the firmware if the portions of the update received comprise the entire update further comprises installing the received portions of the update.

8. An apparatus for propagating firmware updates in a peer-to-peer network environment, the apparatus comprising a computer processor, a computer memory operatively coupled to the computer processor, the computer memory having disposed within it computer program instructions capable of:

identifying, by a downlevel node in a peer-to-peer network, that one or more nodes in the peer-to-peer network have firmware that is uplevel with respect to the downlevel node;

broadcasting, by the downlevel node, an update request requesting an update to the firmware;

receiving, from a plurality of nodes having firmware uplevel with respect to the downlevel node, a plurality of portions of the update, metadata describing each portion of the update received, and metadata describing the firmware installed on each of the plurality of nodes having firmware uplevel with respect to the downlevel node; and

determining, in dependence upon the metadata describing each portion of the update received and the metadata describing the firmware installed on each of the plurality of nodes having firmware uplevel with respect to the downlevel node,

whether the portions of the update received comprise an entire update; and

updating, by the downlevel node, the firmware if the portions of the update received comprise the entire update.

9. The apparatus of claim 8 wherein the computer memory has disposed within it computer program instructions capable of broadcasting again, by the downlevel node, again an update request if the portions of the update received do not comprise the entire update.

10. The apparatus of claim 9 wherein computer program instructions capable of broadcasting again an update request further comprises computer program instructions capable of sending to all of the nodes of the peer-to-peer network an update request that includes an identification of the portions of the update not received in response to the previous broadcast.

11. The apparatus of claim 8 wherein the computer memory has disposed within it computer program instructions capable of:

determining, by the downlevel node in dependence upon metadata describing the firmware installed on each of the plurality of nodes having firmware uplevel with respect to the downlevel node whether one of the nodes sending a portion of the update has a corrupted image of the uplevel firmware; and

notifying, by the downlevel node, the nodes having a corrupted image of the uplevel firmware if one of the nodes sending a portion of the update has a corrupted image of the uplevel firmware.

12. The apparatus of claim 8 wherein computer program instructions capable of identifying, by a downlevel node in the peer-to-peer network, that one or more nodes in the peer-to-peer network have firmware that is uplevel with respect to the downlevel node further comprises computer program instructions capable of receiving a message broadcast from the node having firmware that is uplevel.

13. The apparatus of claim 8 wherein computer program instructions capable of identifying, by a downlevel node in the peer-to-peer network, that one or more nodes in the peer-to-peer network have firmware that is uplevel with respect to the downlevel node further comprises computer program instructions capable of:

periodically broadcasting, by the downlevel node, a request for identification of firmware on other nodes in the peer-to-peer network; and

receiving, in response to the broadcast, a plurality of identifications of firmware installed on a plurality of other nodes in the peer-to-peer network.

14. The apparatus of claim 8 wherein computer program instructions capable of updating, by the downlevel node, the firmware if the portions of the update received comprise the entire update further comprises computer program instructions capable of installing the received portions of the update.

15. A non-transitory computer program product for propagating firmware updates in a peer-to-peer network environment, the computer program product disposed in a computer readable recordable medium, the computer program product comprising computer program instructions for:

identifying, by a downlevel node in a peer-to-peer network, that one or more nodes in the peer-to-peer network have firmware that is uplevel with respect to the downlevel node;

broadcasting, by the downlevel node, an update request requesting an update to the firmware;
