Abstract

Overlay network is a ready-to-use solution to enable new network functionality with existing Internet connectivity intact. This paper introduces a network service which helps users easily compose their own service overlay networks through software-defined networks. We look into the structure of service gateway which enables 1 Gbps packet processing on composed overlay networks. We also provide examples for the way of composing service overlay for support multicast applications. Experiment results carried over the KREONET (Korea Research Environment Open NETwork) show the forwarding performance of the service gateway.

오버레이 네트워크는 인터넷 연결성을 손상시키지 않고 새로운 네트워킹 기능을 제공할 수 있는 현실적인 방안이다. 본 논문은 서비스 오버레이의 용이한 구성을 지원하는 사용자 정의 네트워크 서비스를 소개하고 구성된 오버레이 네트워크 상에서 고속 데이터 평면 처리를 수행하는 서비스 게이트웨이의 하드웨어 및 소프트웨어 구조를 살펴본다. 또한, 멀티캐스트 응용 지원을 위한 서비스 오버레이 네트워크의 생성 과정을 예시한다. 국가과학기술연구망에 구축된 실험환경에서 서비스 게이트웨이의 성능 평가를 수행하고 수백 Mbps급 멀티미디어 서비스의 적용가능성을 확인한다.
