Abstract

Recently, the importance of smart gateways that link these with the big data and the development of the Internet of things is getting bigger. The smart gateway includes a network function such as a router and a router, and a sensor network function that links various objects such as a sensor. As the internet market has expanded, network stability and security problems have arisen and VPN technology has been proposed as one of the ways to solve these security problems. Efficient design is needed to implement VPN in low-end smart gateway and SOHO-level Internet environment with poor line quality. In this paper, we propose the concept and principle of VPN tunneling implementation and real - time traffic shaping method according to internet line condition in the Smart Gateway that supports IOT developed based on OpenWRT, the implementation and measured performance indicators are presented.

최근 스마트 게이트웨이의 중요성이 커지고 있다. 유무선 공유기와 라우터 같은 네트워크 기능이 복합 내재되어 있다. 사물인터넷 시장이 확대되면서 네트워크 안정성과 보안문제가 발생했고 이러한 보안 문제를 해결할 방법 중 하나로 VPN 기술이 제시 되었다. 회선품질이 나쁜 SOHO 환경에서 VPN 구현을 위해서는 효율적인 설계가 필요하다. 본 논문에서는 OpenWRT기반으로 개발한 사물인터넷 지원 스마트 게이트웨이에서 VPN 터널링의 구현방법과 인터넷 회선 상황에 따른 실시간 트래픽 쉐이핑 방법에 대해 개념 및 원리를 제시하며 이에 대한 구현 및 측정한 성능지표를 제시한다.
