현재의 인터넷은 트래픽의 양적 증가뿐 아니라 다양한 응용 수용이라는 질적인 측면의 문제에 봉착했다. 이를 수용하기 위해서 Diffserv 개념이 도입되었으며, 본 논문에서는 프로그램 가능한 네트워크 프로세서 IXP1200를 이용하여 간단한 Diffserv Interior­node PHB의 설계를 통하여 CoS(Class of Service)를 지원하는 Diffserv를 설계하고 구현하였다.

This paper describes sensor network system implementation for the IEEE 1451.2 standard which guarantees compatibilities between various wired sensors. The proposed system consists of the Network Capable Application Processor(NCAP) in the IEEE 1451.0, the Transducer Independent Interface(TII) in the IEEE 1451.2, the Transducer Electronic Data Sheet(TEDS) and sensors. The research goal of this study is to minimize and optimize system complexity for IC design. The NCAP is implemented using C language in personal computer environment. TII is used in the parallel port between PC and an FPGA application board. Transducer is implemented using Verilog on the FPGA application board. We verified the proposed system architecture based on the standards.
