Systems and methods for efficiently using network bandwidth to download resources
View Patent ↗In an exemplary method, a computer system within a subnet of a computer network sends a discovery request to other computer systems within the subnet. The discovery request comprises a request for a resource. The computer system downloads an available portion of the resource from the other computer systems in the subnet. If there is a remaining portion of the resource that is not available from the other computer systems in the subnet but that is available from a remote source, and if there is at least one other computer system in the subnet that is also seeking to obtain the remaining portion of the resource, the computer system negotiates with the at least one other computer system about downloading the remaining portion of the resource from the remote source. If no other computers in the subnet require the resource, then the remaining portion of the resource may be downloaded directly from the remote source.
1. A method for efficiently using network bandwidth to download resources, the method being implemented by a computer system within a segment of a computer network, the method comprising:
sending a discovery request to other computer systems within the network segment, wherein the discovery request comprises a request for at least one resource;
downloading an available portion of the at least one resource from the other computer systems in the network segment; and
if there is a remaining portion of the at least one resource that is not available from the other computer systems in the network segment but that is available from a remote source, and if there is at least one other computer system in the network segment that is also seeking to obtain the remaining portion of the at least one resource, negotiating with the at least one other computer system about downloading the remaining portion of the at least one resource from the remote source.
2. The method of claim 1 , wherein downloading the available portion of the at least one resource from the other computer systems in the network segment comprises downloading the entire resource from a single computer system within the network segment.
3. The method of claim 1 , wherein downloading the available portion of the at least one resource from the other computer systems in the network segment comprises discontinuing to download the at least one resource from the remote source when another computer system in the network segment that has the resource comes online.
4. The method of claim 1 , wherein downloading the available portion of the at least one resource from the other computer systems in the network segment comprises downloading a first part of the at least one resource from a first computer system within the network segment and downloading a second part of the resource from a second computer system within the network segment.
5. The method of claim 1 , wherein the remaining portion of the at least one resource comprises the entire resource.
6. The method of claim 1 , wherein the remaining portion of the at least one resource comprises part of the at least one resource.
7. The method of claim 1 , wherein negotiating comprises selecting a single computer system within the network segment to download the at least one resource from the remote source.
8. The method of claim 1 , wherein negotiating comprises determining which of the computer system and the at least one other computer system has the lowest IP address.
9. The method of claim 1 , wherein the discovery request comprises an identifier for the computer system and at least one other identifier for the at least one resource.
10. The method of claim 1 , wherein the computer system is a managed node in a computer network.
11. The method of claim 1 , wherein the network segment is a subnet within the computer network.
12. The method of claim 1 , wherein the network segment is a multicast alias domain within the computer network.
13. A computer system that is configured to implement a method for efficiently using network bandwidth to download resources, the computer system comprising:
a processor;
memory in electronic communication with the processor;
instructions stored in the memory, the instructions being executable to implement a method comprising:
sending a discovery request to other computer systems within a segment of a computer network, wherein the discovery request comprises a request for at least one resource;
downloading an available portion of the at least one resource from the other computer systems in the network segment; and
if there is a remaining portion of the at least one resource that is not available from the other computer systems in the network segment but that is available from a remote source, and if there is at least one other computer system in the network segment that is also seeking to obtain the remaining portion of the at least one resource, negotiating with the at least one other computer system about downloading the remaining portion of the at least one resource from the remote source.
14. The computer system of claim 13 , wherein downloading the available portion of the at least one resource from the other computer systems in the network segment comprises downloading the entire resource from a single computer system within the network segment.
15. The computer system of claim 13 , wherein downloading the available portion of the at least one resource from the other computer systems in the network segment comprises discontinuing to download the at least one resource from the remote source when another computer system in the network segment that has the resource comes online.
16. The computer system of claim 13 , wherein downloading the available portion of the at least one resource from the other computer systems in the network segment comprises downloading a first part of the at least one resource from a first computer system within the network segment and downloading a second part of the resource from a second computer system within the network segment.
17. A computer-readable storage medium comprising executable instructions for implementing a method for efficiently using network bandwidth to download resources, the method being implemented by a computer system within a segment of a computer network, the method comprising:
sending a discovery request to other computer systems within the network segment, wherein the discovery request comprises a request for at least one resource;
downloading an available portion of the at least one resource from the other computer systems in the network segment; and
if there is a remaining portion of the at least one resource that is not available from the other computer systems in the network segment but that is available from a remote source, and if there is at least one other computer system in the network segment that is also seeking to obtain the remaining portion of the at least one resource, negotiating with the at least one other computer system about downloading the remaining portion of the at least one resource from the remote source.
18. The computer-readable storage medium of claim 17 , wherein downloading the available portion of the at least one resource from the other computer systems in the network segment comprises downloading the entire resource from a single computer system within the network segment.
19. The computer-readable storage medium of claim 17 , wherein downloading the available portion of the at least one resource from the other computer systems in the network segment comprises discontinuing to download the at least one resource from the remote source when another computer system in the network segment that has the resource comes online.
20. The computer-readable storage medium of claim 17 , wherein downloading the available portion of the at least one resource from the other computer systems in the network segment comprises downloading a first part of the at least one resource from a first computer system within the network segment and downloading a second part of the resource from a second computer system within the network segment.
