Open Data Plane – Facebook’s ToR Switch
Facebook's Open Compute Project to give the world an "open" top-of-rack switch. "We should be able to treat a switch like a server in the rack," Frankovsky said. "We should be able to load a Linux-based operating system, and that server just happens to have a lot of I/O ports on it."

“ 네트워크가 우리의 사업과 가정과 학교의 필수적인 인프라가 되었다. 실제 운영 중인 네트워크상에서는 수많은 네트워크의 장비와 프로토콜이 설치되어 있기에 새로운 시도의 트래픽을 생성하는 실험이 거부당한다. 이 결과 네트워크 전문가 집단으로부터 나오는 중요한 아이디어들도 통신 네트워크 상의 시도나 시험조차 포기해 버려야 한다. 이러한 이유로 오늘날의 네트워크는 공룡 화석처럼 경화되었다고 본다”
그럼, 네트워크에서는 무엇이 변했나요?
