Abstract
Technologies are described to control network congestion in packet-based networks. In some examples, a method may include receiving an Interest packet requesting content, and returning the content from a local data store if the content is in the local data store. The method may also include determining whether a previous request has been made for the requested content if the content is not in the local data store, and creating a record of the Interest packet and discarding the Interest packet if a previous request has been made. The method may further include determining whether a local IP routing table includes an entry that matches a destination IP address specified by the Interest packet if a previous request has not been made, and forwarding the Interest packet if the destination IP address is in the local IP routing table.
