초록

ATM기술은 ITU나 ATM Forum과 같은 표준화 기관에서 B-ISDN서비스를 전송하기 위한 기술로 표준화 되어 왔다. 현재는 ATM기술이 복잡하여 인터넷 트래픽을 전송하도록 MPLS와 같은 백본기술로 채택되고 있다. 그러나 ATM프로토콜은 BcN망등에서 많이 채택될 것이다. 본 논문은 ATM기반 시스템에서 네트워크의 정보를 이용하여 HTR코드를 기법을 적용하여, 코드를 검출하고, 등록하는 기법에 대해 논하고 자 한다. 고속의 circuit switching시스템에서 HTR코드 제어는 필수적이며, 본 논문에서는 HTR코드검출 및 Fuzzy제어방식을 통해 실험결과를 보인다. 본 방법에 의해 제시된 실험결과는 체증상태를 신속히 제어하며 시스템 자원을 최대한 활용하고, 적은 부하로서도 효율적으로 제어함을 보인다.

ATM was recommended by the ITU and ATM Forum as a means of transportation for B-ISDN. At this time, due to the comprehensive mature of ATM protocol, ATM has been adapted as the backbone system for carrying Internet traffi $c^{[1,2,3,4]}$. But major conceptsregarding the ATN protocol will be used on future technology. This paper presents preventive congestion control mechanisms for detecting HTR(Hard-To Reach) code in ATM systems, in particular for an improved HTR call registration method using network signaling information will discussed. In high speed circuit switching system environments, a fast HTR control mechanism is necessary. We present research results for improving HTR call registration and control methods using network signaling information and fuzzy control mechanisms. We concluded that it showed fast congestion avoidance mechanisms with a fewer system load maximized the efficiency of network resources by restricting ineffective machine attempts.
