The goal of this project is to solve the inefficiencies in the current Internet caused by bursty traffic and data explosion. The current communication-based Internet architecture does not support efficient distribution of content. A chief drawback of the current architecture is that the end-points in the network are named, and not the content itself. Thus, in order to retrieve content, one is forced to address the location of the content and not the content itself. Moreover since both location and content are closely tied, every request for the same content travels over the network to the source of the content, thus making inefficient use of the available resources and creating bottlenecks in the network. Thus, this project proposes to develop and evaluate key software for efficient networking that focuses on content networking.

To achieve the goal of efficient content networking, this project develops network software based on the technical concept named, Content-Centric Networking (CCN). CCN is an evolving distribution architecture envisioned by PARC that enables efficient and secure distribution of content than is currently feasible.

When clients want to share data, they publish each data object to the network with a name (and description) called a content object. When they want to retrieve content, they ask the network to retrieve the content for them based on a name (or a description). Because the data (or content objects) can be cached anywhere in the network, it can be retrieved from a location closest to the client, thereby significantly improving the network efficiency and user-perceived latency. Based on the above technical changes, this project proposes the following
