Abstract

NFV is a technology that allows network services to be controlled and managed in software by separating various net work functions (NFs) from hardware devices in dedicated network equipment and implementing them in a high-performance general-purpose server. Therefore, standardized virtualization of network functions is one of the most important factors. However, until the introduction of NFV to provide commercial services, there are many technical issues to be solved such as guaranteeing performance, stability, support for multi-vendor environment, ensuring perfect interoperability, and linking existing virtual and non-virtual resources. In this paper, we propose a method to provide an end-to-end network virtualization service based on OSM R2 in KREONET.

NFV는 다양한 네트워크 기능(NF: Network Function)들을 전용 네트워크 장비내의 하드웨어 장비로부터 분리하여 고성능 범용 서버에 구현함으로써 소프트웨어적으로 네트워크 서비스가 제어 및 관리 되도록 하는 기술을 말한다. 따라서 NFV에서는 네트워크 기능들의 표준화된 가상화 지원 여부가 가장 중요한 요소 중의 하나이다. 그러나 NFV를 도입하여 상용 서비스를 제공하기까지는 성능, 안정성 보장, 멀티 벤더 환경 지원, 완벽한 상호호환성 보장, 기존의 가상 및 비가상 자원간 연동 등 해결해야 할 많은 기술 이슈를 남겨놓고 있는 실정이다. 이를 위해 본 논문에서는 OSM R2를 기반으로 첨단연구망 종단간 네트워크 가상화 서비스를 제공하기 위한 방안을 제안하였다.
