Abstract
본 발명은 CDMA 시스템 네트워크뿐만이 아니라 일반 교환 시스템의 각 프로세서간 통신 네트워크를 구성할 수 있는 노드간의 포레임 스위치 장치인 고속 패킷 스위치 장치에 관한 것으로서, 그 특징은 고속 패킷 스위치 장치에 있어서, 4가지의 동작 모드로 입출력 신호선 폭을 시스템 설정시와 운용중 변경 지정할 수 있으며 스위치 자체 시험시 시험용 프레임을 선택하며 스위치 입력 신호선을 스위치 내부 전송 신호선 폭으로 변환하는 데이터 변환수단과, 프레임의 어드레스 영역으로부터 순수 어드레스 비트를 추출하는 어드레스 재구성 수단과, 상기 어드레스 재구성 수단에 의해 어드레스가 재구성되는 데에 소요되는 시간동안 프레임 전송을 지연시키는 지연수단과, 프레임의 경로를 결정하는 경로 제어 수단과, 프레임 단위 측면에서 비동기 방식으로 입력되는 모든 입력 포트로부터의 프레임들을 집중시키는 프레임 집중 수단과, 실질적인 프레임 데이터가 저장되는 프레임 입시저장 수단과, 균일한 프레임 버퍼의 크기를 유지시키기 위하여 버퍼를 제어하는 버퍼 제어 수단과, 상기 다수의 프레임 임시저장 수단으로부터 하나의 출력 포트로 프레임을 출력시키는 버퍼 스위치 수단 및 스위치 내부 전송 신호선을 스위치 출력선 폭으로 변환하는 데이터 변환수단을 포함하는 데에 있으므로, 본 발명은 스위칭 방식의 고속 패킷 교환으로 실시간 처리를 요구하는 프레임 전송 서비스가 가능하며, 가변길이의 패킷 프레임에 대한 스위칭이 가능하므로 기존의 HDLC 프레임 형태를 수용하는 통신장치에 적용하여 경제성을 극대화시킬 수 있고 고속 패킷 스위치의 각 입출력단에 데이터 변환기가 있어서 스위치 내부 구조와 무관하게 다양한 입출력 신호선 폭을 수용하여 다양한 통신 네트워크에서의 응용이 가능하다는 데에 그 효과가 있다.The present invention relates to a high-speed packet switch device that is a node-to-node frame switch device capable of forming a communication network between each processor of a general switching system as well as a CDMA system network. In operation mode, the input / output signal line width can be changed during system setting and operation, and the data conversion means for selecting the test frame during the switch self-test and converting the switch input signal line to the internal transmission signal line width, and the pure address from the address area of the frame Address reconstruction means for extracting bits, delay means for delaying frame transmission for the time required to reconstruct the address by the address reconstruction means, path control means for determining the path of the frame, and asynchronous in terms of frames system Frame concentrating means for concentrating frames from all input ports inputted into the frame, frame entrance and storage means for storing substantial frame data, buffer control means for controlling a buffer to maintain a uniform frame buffer size, and the plurality of The present invention provides buffer switching means for outputting a frame from one frame temporary storage means to one output port, and data conversion means for converting a switch internal transmission signal line into a switch output line width. It is possible to provide frame transmission service that requires real-time processing and to switch to variable length packet frame, so that it can be applied to communication device that accepts existing HDLC frame type to maximize economic efficiency and each input / output end of high speed packet switch. Has a data converter Regardless of the location inside the structure to accommodate a variety of input and output signal lines has a width that effect to the application it is possible in a variety of communication networks.
