Efficient Distance based Response Time Pruning Cache Policy for NDN

Abstract

In today’s world, usage of the Internet is growing day by day. The contents that can be accessed with a single swipe of a finger are growing and changing. However, the present network is designed in such a way that it is impossible to respond quickly to content overflow issues. When numerous users make extensive requests for content, the bottleneck problem emerges. The Named Data Network (NDN) has emerged as a viable option for future networks to address this issue. NDN is an emerging paradigm that follows content-based communication rather than IP addresses. NDN effectively utilizes network capacity by employing a caching function at the intermediate nodes of the network to enhance network efficiency. Doing this minimizes network response time and increases the network cache hit ratio. In such a context, we suggest an NDN-based cache strategy that can increase network efficiency. The proposed scheme is evaluated through simulations which show better results as compared to native NDN cache policies in terms of response time and hit ratio.
