QoS Aware Path Selection in Content Centric Networks

Free registration required

Executive Summary

With the availability of higher network bandwidths, greater computing power, and a shift to more content centric use of the internet, researchers are revisiting the Internet architecture. One such effort is the Content Centric Networking (CCN) project where content driven data, rather than nodes, is primarily used for enabling communications. CCN include state maintenance at the intermediate network nodes and allow multiple paths to the content; two aspects absent in the current Internet architecture. Compared to the authors' approach, random forwarding gives only 63% of attainable bandwidth and twice the average per packet delay.
