Abstract

TCP/IP is a P2P transmission and has low network resource utilization. It focuses on the host, rather than on the content. TCP/IP is designed for resource sharing and this is contrary to the contemporary user who relies more on the information and content sharing, rather than the location of the data itself.

Information Centric Networking (ICN) is a networking paradigm that aims to address the limitations of the current host-centric networking model by focusing on the content itself as the primary entity of the network. In ICN, data is addressed and routed based on its content name rather than the location of the host or server, which can improves efficiency, scalability, and security of the network.

ICN also incorporates caching mechanisms which can be optimised by limiting packet blocking and packet dropping. This will enable data to be stored at intermediate nodes along the path of the data, reducing the need for data to travel long distances across the network. However, ICN also poses several challenges, such as the need for efficient naming and addressing schemes, scalable routing algorithms and secure mechanisms for protecting data in transit.

In this research we therefore successfully looked at how caching can be optimised, by studying the payload and maximum transmission unit of a packet. The research on the packets revealed that caching could be optimized, up to a certain load for some networks. We also we present a scheme with improved scalability which incorporates caching mechanisms. This is to enhance the quality of service by minimizing the number of packets that are dropped and blocked. To minimise these critical parameters, a new layout for the cache is proposed. The buffer size is also studied.
