초록

다양한 디바이스와 인터넷 플랫폼의 발달로 콘텐츠에 대한 생산과 수요가 급증하고 있다. 하지만 현재 TCP/IP 체계에서는 기하급수적으로 증가하는 데이터 사용에 대해 효율적인 대처가 어려운 실정이다. 이에 따라, CCN이라는 대안이 등장하면서 호스트 중심에서 콘텐츠 중심으로 데이터를 송수신하면서 좀 더 경감된 네트워크 자원으로 대용량 콘텐츠를 다룰 수 있게 되었다. 이번 논문에서는 CCN에서 연구되는 분야 중의 하나인 중간노드 이동성에 대해서 다룰 것이다. CCN에서 실시간 서비스는 정보제공자뿐만 아니라 정보요청자에게도 매우 중요한 요소이다. 그러나 노드 이탈 상황이 발생하면 패킷 전송량과 전송속도 저하가 발생하게 된다. 그래서 위와 같은 수치를 보장하기 위해 이중 경로를 이용하여 중간노드가 이탈하더라도 대체 경로를 이용해 완벽한 QoS(: Quality of Service)를 제공한다.

With the development of various devices and Internet platforms, production and demand for content are increasing rapidly. However, effective response to exponentially increasing data usage is difficult in current TCP/IP schemes. As a result, with the emergence of an alternative called CCN, data can be transmitted and received from the host-centered to the content-oriented, and large-capacity content can be handled with more mitigated network resources. In this paper, we will address intermediate node mobility, which is one of the areas studied in CCN. In CCN, real-time services are a very important factor for information providers as well as requestors. However, when a node departure situation occurs, packet transmission and transmission speed decreases. Therefore, to ensure these numbers, even if the intermediate node deviates using a dual path, it provides a complete QoS (Quality of Service) using an alternative path.
