Abstract

With the technology of the 4th industrial revolution, network traffic is increasing due to an increase in supply, an increase in demand, and an increase in the complexity of traffic patterns. SDN, a concept in which H/W and S/W are separated in order to efficiently manage such massive traffic, is attracting attention as a next-generation network. A lot of research is being conducted on the merits of applying flexible policies by avoiding the problem of rigid vendor dependency by using the SDN controller implemented with S/W Opensource. Therefore, in this paper, we propose an efficient load balancing technique by grouping through the packet structure of the network layer using the control layer and infrastructure layer of SDN and analyzing the packet delay and reception rate.

4차 산업혁명 기술로 네트워크 트래픽은 공급의 증가, 수요의 증가, 트래픽 패턴의 복잡도 증가의 특징으로 유통되는 Data가 늘고 있다. 이런 방대한 트래픽을 효율적으로 관리하기 위해 H/W와 S/W가 분리된 개념인 SDN이 차세대 네트워크로 주목받고 있다. S/W Opensource로 구현된 SDN의 Controll Layer, Infrastructure Layer 컨트롤러를 이용하여 경직된 Vendor 종속성의 문제를 탈피하여 유연한 정책을 적용할 수 있는 장점으로 많은 연구가 진행되고 있다. 이에 본 논문에서는 SDN을 이용하여 네트워크 계층의 패킷 구조를 통해 그룹화하고 Packet Delay, Transmission Rate 등을 분석하여 효율적인 부하분산 기법을 제안한다.
