Abstract

The disclosed computer-implemented method includes determining that incoming media item requests are to be skewed from a random distribution among server nodes, using a random distribution algorithm, to a directed distribution among the server nodes. The method then includes identifying, in a loading assignment, which media items are to be loaded onto specific server nodes to produce the directed distribution of media item requests. The method next includes preloading the identified media items onto the server nodes according to the loading assignment and receiving media item requests for the preloaded media items. The method then includes routing the received media item requests to the server nodes using the random distribution algorithm, where the random distribution algorithm is skewed to the directed distribution based on the preloading of the media items according to the identified loading assignment. Various other methods, systems, and computer-readable media are also disclosed.

Claims (38)

1 . A computer-implemented method comprising:

determining, for one or more electronic devices, which server nodes are capable of providing media items to the electronic devices;

prior to receiving media item requests, pre-calculating a server node ranking that ranks the determined server nodes according to their ability to form a peer-to-peer connection with one or more other server nodes, resulting in a list of ranked server nodes, wherein the pre-calculated server node ranking includes those server nodes that are capable of creating a network connection to the electronic devices and those server nodes that have internet protocol (IP) addresses that are within a specified range of IP addresses;

identifying, based on the list of ranked server nodes, which server node is best suited to form a peer-to-peer connection with a specified second server node selected from the determined server nodes; and

establishing a peer-to-peer connection between the identified server node and the second server node.

2 . The computer-implemented method of claim 1 , further comprising, upon determining that the peer-to-peer connection has been established:

requesting transfer of one or more of the media items from the second server node to the identified server node over the peer-to-peer connection; and

receiving the one or more media items from the second server at the identified server node.

3 . The computer-implemented method of claim 2 , further comprising storing the received media items on one or more storage devices associated with the identified server node.

4 . The computer-implemented method of claim 2 , further comprising streaming the received media items to one or more requesting client devices.

5 . The computer-implemented method of claim 1 , wherein the pre-calculated server node ranking is based on one or more media item provisioning factors.

6 . The computer-implemented method of claim 1 , wherein the server node ranking is extended to include rankings for one or more server clusters based on one or more media item provisioning factors.

7 . The computer-implemented method of claim 6 , wherein the media item provisioning factors include at least one of proximity, cost, geography, server node health, popularity, server node processing hardware, or server node networking hardware.

8 . The computer-implemented method of claim 1 , wherein server nodes having specified rankings in the precalculated server node ranking are selected to provide media items to a specified electronic device according to one or more established policies.

9 . The computer-implemented method of claim 8 , wherein the specified electronic device is identified as being part of a set of electronic devices based on an associated identifier.

10 . The computer-implemented method of claim 9 , wherein the associated identifier of the specified electronic device comprises an internet protocol (IP) address.

11 . The computer-implemented method of claim 10 , wherein the IP address of the specified electronic device is part of a classless inter-domain routing (CIDR) block of IP addresses.

12 . The computer-implemented method of claim 11 , wherein the set of electronic devices for which server nodes are capable of providing media items is represented by the CIDR block.

13 . The computer-implemented method of claim 11 , wherein the precalculated server node ranking ranks each of the server nodes who service IP addresses in each CIDR block.

14 . A system comprising:

at least one physical processor; and

physical memory comprising computer-executable instructions that, when executed by the physical processor, cause the physical processor to:

determine, for one or more electronic devices, which server nodes are capable of providing media items to the electronic devices;

prior to receiving media item requests, pre-calculate a server node ranking that ranks the determined server nodes according to their ability to form a peer-to-peer connection with one or more other server nodes, resulting in a list of ranked server nodes, wherein the pre-calculated server node ranking includes those server nodes that are capable of creating a network connection to the electronic devices and those server nodes that have internet protocol (IP) addresses that are within a specified range of IP addresses;

identify, based on the list of ranked server nodes, which server node is best suited to form a peer-to-peer connection with a specified second server node selected from the determined server nodes; and

establish a peer-to-peer connection between the identified server node and the second server node.

15 . The system of claim 14 , wherein the precalculated server node ranking is provided to at least a plurality of the server nodes.

16 . The system of claim 15 , wherein the computer-executable instructions further comprise:

determining that rankings have changed for one or more of the server nodes based on one or more media item provisioning factors; and

propagating the rankings changes for those server nodes, such that the precalculated server node ranking is updated using only the rankings changes for those server nodes.

17 . The system of claim 14 , wherein server nodes having specified rankings in the precalculated server node ranking are selected to provide the media item to a specified electronic device according to one or more established policies.

18 . The system of claim 17 , wherein the computer-executable instructions further comprise validating one or more network routes between the specified electronic device and one or more of the server nodes to ensure that the network routes provide a threshold level of data transfer.

19 . The system of claim 17 , wherein the computer-executable instructions further comprise filtering one or more network routes between the specified electronic device and one or more of the server nodes to prevent erroneous routes or routes to malicious server nodes.

20 . A non-transitory computer-readable medium comprising one or more computer-executable instructions that, when executed by at least one processor of a computing device, cause the computing device to:

determine, for one or more electronic devices, which server nodes are capable of providing media items to the electronic devices;

prior to receiving media item requests, pre-calculate a server node ranking that ranks the determined server nodes according to their ability to form a peer-to-peer connection with one or more other server nodes, resulting in a list of ranked server nodes, wherein the pre-calculated server node ranking includes those server nodes that are capable of creating a network connection to the electronic devices and those server nodes that have internet protocol (IP) addresses that are within a specified range of IP addresses;

identify, based on the list of ranked server nodes, which server node is best suited to form a peer-to-peer connection with a specified second server node selected from the determined server nodes; and

establish a peer-to-peer connection between the identified server node and the second server node.
