본 논문에서는 HCR(hierarchical-cell-resequencing) 메커니즘과 고속 WDM 상호연결을 기반으로 한 비차단 다단계 ATM 스위치를 제안하고 그 타당성 조사를 보고한다. 다단계 ATM 스위치에서 셀 기반 라우팅은 스위치를 비차단 상태로 만드는 데 효과적입니다. 왜냐하면 모든 트래픽이 중간 스위칭 단계를 통해 무작위로 분산되기 때문입니다. 그러나 다중 경로 조건으로 인해 셀이 스위칭 패브릭의 출력에 순서 없이 도착할 수 있습니다. 따라서 최종 스위칭 단계의 각 출력이나 각 스위칭 단계의 출력에서 재시퀀싱을 수행해야 합니다. 기본 HCR 스위치는 셀을 입력 라인에서 출력 라인으로 전환할 때 계층적 방식으로 셀 재배열을 수행합니다. 결과적으로, 기본 HCR 스위치의 각 출력의 셀 시퀀스가 복구됩니다. 다단계 HCR 스위치는 이러한 기본 HCR 스위치의 입력선과 출력선을 계층적으로 상호 연결하여 구성됩니다. 따라서 스위칭 패브릭의 각 최종 출력에 있는 셀 시퀀스는 계층적 방식으로 보존됩니다. 이러한 방식으로 셀 기반 라우팅이 가능해지며 HCR 메커니즘을 갖춘 다단계 ATM 스위치는 내부 속도 향상 기술 없이 100% 처리량을 달성할 수 있습니다. 대용량 다단 HCR 스위치에는 엄청난 수의 고속 신호 접속이 필요하기 때문에 컴팩트한 광 접속 기술의 획기적인 발전이 필요합니다. 따라서 본 논문에서는 고속 스위치 소자들을 효과적으로 상호 연결하는 광 라우터 배열 도파관 필터(AWGF)를 이용한 WDM 상호 연결 시스템을 제안하고 그 타당성 조사를 보고한다. 이 아키텍처에서 각 스위치 요소는 고유한 파장으로 처리됩니다. 결과적으로 이전 단계의 스위치는 셀 전송 파장만 선택하여 다음 단계의 스위치로 셀을 전송할 수 있습니다. 이 시스템을 실현하기 위해 우리는 소형 고출력 전기흡수 분산 피드백(EA-DFB) 레이저와 새로운 비트 결정 회로를 갖춘 넓은 채널 간격의 광 라우터 AWGF와 소형 10Gbit/s 광 송신기 및 수신기 모듈을 개발했습니다. . 이 모듈을 사용하여 WDM 상호 연결의 안정적인 작동을 확인했습니다. 이 스위치 아키텍처와 WDM 상호 연결 시스템을 통해 1Tbit/s 이상의 처리량을 달성할 수 있는 고속 ATM 스위칭 시스템을 개발할 수 있습니다.

Abstract: This paper proposesd a non-blocking multi-stage ATM switch based on a hierarchical-cell-resequencing (HCR) mechanism and high-speed WDM interconnection and reports on its feasibility study. In a multi-stage ATM switch, cell-based routing is effective to make the switch non-blocking, because all traffic is randomly distributed over intermediate switching stages. But due to the multi-path conditions, cells may arrive out of sequence at the output of the switching fabric. Therefore, resequencing must be performed either at each output of the final switching stage or at the output of each switching stage. The basic HCR switch performs cell resequencing in a hierarchical manner when switching cells from an input-lines to a output-line. As a result, the cell sequence in each output of the basic HCR switch is recovered. A multi-stage HCR switch is constructed by interconnecting the input-lines and output-lines of these basic HCR switches in a hierarchical manner. Therefore, the cell sequence in each final output of the switching fabric is conserved in a hierarchical manner. In this way, cell-based routing becomes possible and a multi-stage ATM switch with the HCR mechanism can achieve 100% throughput without any internal speed-up techniques. Because a large-capacity multi-stage HCR switch needs a huge number of high-speed signal interconnections, a breakthrough in compact optical interconnection technology is required. Therefore, this paper proposes a WDM interconnection system with an optical router arrayed waveguide filter (AWGF) that interconnects high-speed switch elements effectively and reports its feasibility study. In this architecture, each switch element is addressed by a unique wavelength. As a result, a switch in a previous stage can transmit a cell to any switch in the next stage by only selecting its cell transmission wavelength. To make this system feasible, we developed a wide-channel-spacing optical router AWGF and compact 10-Gbit/s optical transmitter and receiver modules with a compact high-power electroabsorption distributed feedback (EA-DFB) laser and a new bit decision circuit. Using these modules, we confirmed stable operation of the WDM interconnection. This switch architecture and WDM interconnection system should enable the development of high-speed ATM switching systems that can achieve throughput of over 1 Tbit/s.
