Abstract

Content-Centric Networking(CCN) is a new networking paradigm to search for the routing information needed to find a data from the content name, unlike conventional IP networks. In CCN, the mobility management, one of the CCN challenges, is consists of consumer mobility and content provider mobility. Among both, in the case of the content provider mobility, it requires too much overhead and time to update routing information on the corresponding routers. In this paper, we propose Popularity-based Pushing CCN(PoPCoN) which considers the content popularity to support effective mobility of content provider in CCN. Our proposed algorithm shortens content download time for the consumer and reduces the network overhead during mobility as compared to the existing approaches.

콘텐츠 중심 네트워크(CCN)는 데이터를 찾는데 필요한 라우팅 정보를 콘텐츠 이름에서 찾는 방식으로 기존의 IP 방식과는 다른 새로운 네트워킹 패러다임이다. CCN의 도전과제 중 하나인 이동성 관리는 크게 정보요청자의 이동과 정보제공자의 이동을 들 수 있다. 그 중에서도 정보제공자 이동의 경우 해당되는 라우터의 경로 정보를 갱신해야 하므로 많은 오버헤드와 시간이 필요하다. 이에 본 논문은 CCN에서 효율적인 정보제공자의 이동성 지원을 위해 콘텐츠의 인기도를 고려한 Popularity-based Pushing CCN(PoPCoN)을 제안한다. 제안하는 알고리즘은 기존의 기법과 비교하여 요청자의 콘텐츠 다운로드 시간을 단축시키고 네트워크의 오버헤드를 감소시킨다.
