인터넷 트래픽의 향후 5년간 연평균성장률(CAGR)은 24%(유선 트래픽이 21%, 모바일 트래픽이 68%)로 예상되지만, 인터넷 트래픽을 처리하는 칩셋의 성능 연평균성장률은 14% 정도로 예상되고 있다. 이에 따라, 증가하는 인터넷 트래픽과 이를 처리하는 칩셋의 성능 사이에 격차(Forwarding Gap)가 발생하고 있는 상황이다. 이런 격차를 줄이기 위해 시작된 연구기술이 데이터 플레인 가속화(DPA: Data Plane Acceleration) 기술이다. 본고에서는 데이터 플레인 가속화 기술로 최근 공개 소프트웨어로 발표된 인텔의 DPDK(Data Plane Development Kit)기술과 Linaro의 ODP(Open Data Plane)기술을 중심으로 고속 네트워크 패킷처리를 위한 데이터 플레인 가속화 기술동향을 소개한다.
