초록

전 세계 데이터 총량이 2025년이면 175 ZB로 늘어날 것으로 전망되면서[1] 네트워크 영역에서의 데이터 처리 능력은 더욱 중요해지고 있다. 특히 데이터센터는 데이터 사용량이 늘어남에 따라 고집적화되고 있어서 유입되는 데이터로부터 유발되는 부하는 비용 절감과 효율적인 운영 등을 위해 적절히 분산되어야 한다. 기존 네트워크 체계의 한계점을 극복하기 등장한 SDN 기술은 네트워크 장비에서 H/W와 S/W를 분리하여 Legacy 체계의 경직성을 해소하는데, S/W 기반의 유연성을 이용해서 데이터센터에서의 부하분산에 효과적으로 적용할 수 있다. 본 논문에서는 SDN 기술을 활용하여 사용자로부터 받은 데이터를 유형별로 분류하고, 분류된 데이터를 데이터센터내 서버의 응답시간 순서대로 전송·처리함으로써 효율을 높일 수 있는 방법을 제안한다.

With global data totals expected to grow to 175 ZB by 2025, data processing capabilities in the network area are becoming more important. In particular, data centers are becoming more stubborn as data usage increases, and the load generated by incoming data should be appropriately distributed to reduce costs and efficiently operate. The SDN technology, which emerged to overcome the limitations of the existing network system, removes rigidity of the Legacy system by separating H/W and S/W from the network equipment, and can be effectively applied to load balancing in the data center using S/W-based flexibility. In this paper, we propose ways to increase efficiency by classifying data received from users by type by utilizing SDN technology, and transmitting and processing classified data in order of response speed of servers in the data center.
