Newnode: decentralized content distribution network
A method and apparatus of a device that downloads content to a local device using a decentralized content distribution network is described. In an exemplary embodiment, the device receives a request from an application to download content using the decentralized content distribution network. In addition, the device determines a plurality of nodes in the decentralized content distribution network to download the content. For each of the plurality of nodes, the device attempts to establish communications between the device and that node. In addition, the device downloads a portion of the content from that node if communication is established between the local device and that node, wherein the size of the portion is based on at least a characteristic of that node. Furthermore, the device downloads a portion of the content from a proxy if communication cannot be established between the local device and that node, wherein the size of the portion is based on at least a characteristic of that proxy.
1. A non-transitory machine-readable medium having executable instructions to cause one or more processing units to perform a method to download content to a local device using a decentralized content distribution network, the method comprising:

determining a portion of the content to be downloaded for that node using a heuristic, wherein the heuristic is based on at least one of node address, content size, latencies to other nodes, throughput, and performance of other nodes on the same network, and the local device saves at least one of latencies, performance, and throughput from previous content requests, and
downloading the portion of the content from that node, wherein each node in the plurality of nodes has a different number of portions for download and a portion size for one of the plurality of nodes is different than a portion size for another one of the plurality of nodes.
2. The machine-readable medium of claim 1 , wherein the heuristic can include a factor based on a newness of one of the plurality of the nodes.
3. The machine-readable medium of claim 1 , wherein the local device infers performance data from another one of the plurality of nodes that are on the same network as the local device.
4. The machine-readable medium of claim 1 , wherein the determining a size of the content comprises: sending a content request for the content from a node; receiving the response from the node; and determining the size of the content from a header in the response.
5. The machine-readable medium of claim 4 , wherein content request is one of a Hypertext Transfer Protocol GET request and a Hypertext Transfer Protocol HEAD request.
6. The machine-readable medium of claim 1 , wherein the local device communicates with at least one of the plurality of nodes or the proxy using the Low Extra Delay Background Transport protocol.
7. The machine-readable medium of claim 1 , wherein the content is cryptographically signed.
8. The machine-readable medium of claim 7 , wherein the cryptographic signed content includes a Merkle tree.
9. A method to download content to a local device using a decentralized content distribution network, the method comprising:
receiving an application request, at the local device, from an application to download content using the decentralized content distribution network; determining a size of the content; determining a plurality of nodes in the decentralized content distribution network to download the content; and for each node in the plurality of nodes,
determining a portion of the content to be downloaded for that node using a heuristic, wherein the heuristic is based on at least one of node address, content size, latencies to other nodes, throughput, and performance of other nodes on the same network, and the local device infers performance data from another one of the plurality of nodes that are on the same network as the local device, and
downloading the portion of the content from that node, wherein each node in the plurality of nodes has a different number of portions for download and a portion size for one of the plurality of nodes is different than a portion size for another one of the plurality of nodes.
10. The method of claim 9 , wherein the local device saves at least one of latencies, performance, and throughput from previous content requests.
11. The method of claim 9 , wherein the heuristic can include a factor based on a newness of one of the plurality of the nodes.
12. The method of claim 9 , wherein the determining a size of the content comprises: sending a content request for the content from a node; receiving the response from the node; and determining the size of the content from a header in the response.
13. The method of claim 12 , wherein content request is one of a Hypertext Transfer Protocol GET request and a Hypertext Transfer Protocol HEAD request.
14. The method of claim 9 , wherein the local device communicates with at least one of the plurality of nodes or the proxy using the Low Extra Delay Background Transport protocol.
