This paper describes the implementation of the accelerated virtual switch using Intel DPDK(Data Plane Development Kit), and evaluates the virtual network functions of the virtual switch which is one of the most important components to build a virtual network for cloud computing. Nowadays, new information service platforms are appeared from the interconnection of intelligent IT systems like IoT(Internet of Things). And many companies want to use the new service platform for their new application service. The companies can apply there new service early which needs small investment and responses adaptively to the fast change of consumer environment. Using cloud computing technology, the new business service can be introduced as a commercial IT service for the time to market. In this study, an implementation and investigation were performed for the accelerated virtual switch, called Intel DPDK virtual switch, which is using multi processors in network interface card for virtual network functions. It can be useful for Internet-oriented companies to leverage the new cloud service and businesses for its creativeness.

유무선 네트워크 기술의 급격한 발전 및 개인용 휴대 장치의 보급 증가와 그에 맞물린 소셜네트워크 서비스 등의 활성화로 인해 데이터의 전송량이 폭발적으로 늘어나고 있으며, 이러한 추세는 향후 지속될 것으로 전망된다. 이에 데이터센터의 수요가 증가하고 있으며, 확장 및 유지보수가 쉬우면서도 높은 성능을 갖는 시스템에 대한 요구가 높아지고 있다. 본 논문에서는 데이터센터 네트워크의 구성요소를 분석하고 각각의 지연시간을 알아보았으며, 그 중 확장 및 유지보수가 쉬우나 상대적으로 지연시간이 높은 이더넷을 데이터센터에 적용하였을 때 지연시간 개선을 위한 방법으로 Intel DPDK를 적용할 경우, 미적용시와 비교하여 약 86%의 지연시간 감소를 확인하였고, 추가 향상 방안을 조망하였다.

Commercial Off The Shelf(COTS) based one-way communication is advantageous in that support a low cost communication and high speed one-way communication. This paper introduce a one-way communication method, and provides a implementation method of one-way communication through modified device driver for COTS NIC. Then, To verify the advantage of the COTS based one-way communication method, We present a sample implementation using Intel 82580 NIC, and present a possibility that can contribute to the realization of one-way communication through experiments on performance and reliability.
