Abstract
Provided is a method for content popularity extraction from a distributed hash table (DHT). The method includes receiving, by a first node, a request message from a second node of a peer-to-peer network. Accessing, by the first node, information associated with the request message, the information indicating a content item and a content demand. And determining, by the first node, a content popularity of a plurality of content items based on the information.
Claims10
A method, comprising:
- receiving, by a first node, at least one request message from at least one second node of a peer-to-peer network;
- determining, by the first node, information associated with the at least one request message, the information indicating a content item and at least one internet service provider (ISP) associated with the at least one second node, the at least one ISP is associated with the peer to peer network;
- determining, by the first node, a content popularity of the content item for the at least one ISP based on at least a logical distance of the content item from an associated identifier and a number of distinct nodes requesting the content item;
- and
- providing the content item to a requesting node based on the content popularity.

A node of a peer-to-peer network, the node comprising:
- a memory configured to store a table, the table including a plurality of keys and node information, the node information being stored in relation to each of the plurality of keys;
- and
- a processor configured to,
- receive at least one request message from at least one second node of the peer-to-peer network based on an address associated with one of the plurality of keys,
- determine information associated with the at least one request message, the information indicating a content item and at least one internet service provider (ISP) associated with the at least one second node, the at least one ISP is associated with the peer to peer network;
- determine a content popularity of the content item for the at least one ISP based on at least a logical distance of the content item from an associated identifier and a number of distinct nodes requesting the content item, and
- provide the content item to a requesting node based on the content popularity.
