Status-Based Content Sharing Mechanism for Content-Centric Network

摘要

In current Content-Centric Networking (CCN),client receives contents via broadcasting interest request,replacing the typical point-to-point communication in traditional TCP/IP.However,original CCN has drawbacks like low network utilization and packets redundancy in some scenarios.This paper proposes Status-Based Content Sharing Mechanism (SBCSM) for CCN,which helps reducing redundant CCN-packet traffic by choosing the most suitable content-source based on server's status.To demonstrate our work,we develop a file-sharing application using SBCSM,and test it in different topology and demand scenarios.The evaluation show a promising result that the SBCSM achieve better performance in network utilization,with 20％ dropping of overheads and 50％ higher transfer rate,comparing to traditional CCN routing mechanism.
