Content Centric Network: Solution over IP Network Issues

Abstract

Current internet architecture was designed a long time ago. This architecture was designed considering less number of hosts and scarce computational resources. But now, computational resources are very cheap. So network size is very large now resulting tremendous increase in the traffic over the network. Current IP networks as well as Content Delivery Networks are end point centric. But do end points really matter? Various studies depict that current network is oriented about information mostly. Users are concerned about only information; don’t matter from where they get information. Users don’t care about the location of the information. So, network should be designed in such a way that information is very close to the user resulting decrease in the traffic over the network. In this paper, we cover the issues of current IP network and then how the CCN (Content Centric Networks) can be solution for these issues. We will also focus on Publish Subscribe paradigm.
