기존의 컴퓨터 시스템에서는 인터넷의 대표적인 통신 프로토콜인 TCP/IP 가 호스트 CPU 에서 처리되는데, 이는 호스트 CPU 에 많은 부하(load)를 발생시켜 전체 시스템의 성능을 저하시키는 문제를 야기한다. 최근 이러한 문제점을 해결하는 방안으로서 네트워크 어댑터에서 TCP/IP 를 처리하는 TOE(TCP/IP Offload Engine)에 대한 연구가 활발히 진행되고 있다. 이러한 TOE 가 성공적으로 컴퓨터 시스템에 적용되는 위해서는 이를 지원하는 운영체제용 커널 모듈의 개발이 필요하며, 커널 모듈은 기존의 TCP/IP 를 위한 소켓 인터페이스를 바이너리 수준에서 호환성을 제공해야 한다. 따라서, 본 논문에서는 Linux 시스템에서 소켓 인터페이스에 대한 바이너리 수준의 호환성을 제공하는 TOE 용 커널 모듈을 제안하고 개발하였다. 또한, 실험의 통하여 TOE 커널 모듈이 CPU 에 부하를 거의 발생시키지 않음을 확인하였다.
