Abstract
An apparatus including a network interface to a first portion of a network and a second portion of a network. A deep-packet-inspection (DPI) unit identifies a content source, inspects one or more packets provided from the identified source over the first network portion, each packet having a source address and a destination address. A storage stores at least a portion of the content. A content delivery unit receives a request from the second network portion for requested content from the identified source and responsive thereto provides the requested content, or portions of the requested content, from the storage to the second network portion if the requested content, or a portion of the requested content, is stored in the storage, or otherwise sends the request over the first network portion to the identified source for the requested content, or missing portions of the requested content.
