우리는 이미 고객에게 LAN 환경과 그룹 통신 서비스를 제공하는 지역 PC 통신 네트워크 시스템을 제안한 바 있습니다. 가입자의 가정에 보급형 카드(LECard)가 설치되어 널리 사용되는 이더넷 인터페이스(10Base-T)를 제공합니다. MBR(Multiplex-Port Broouter)은 비용 효율적인 방식으로 많은 고객을 수용하기 위해 개발되었습니다. 이더넷 패킷은 HDLC 프로토콜을 사용하여 LECard와 MBR 사이의 각 가입자 채널을 통해 전송됩니다. LECard와 MBR은 그룹 관리 서버(GMS)에 의해 제어되어 그룹 통신 시스템을 구현합니다. 시스템을 실제로 사용하기 전에 일반적인 사용에서 실험 시스템의 성능을 평가해야 합니다. 그러나 다중 접속에서 나타나는 성능 저하를 평가하기 위해서는 여러 대의 PC를 준비하고 동시에 사용하는 것이 어렵습니다. 본 논문에서는 MBR 성능을 평가하기 위해 새로 개발된 다중 액세스 시뮬레이터를 제시합니다. 시뮬레이터는 다중화 신호 인터페이스를 통해 테스트 중인 MBR에 연결됩니다. 다수의 LECard와 PC가 MBR에 연결되어 동시에 네트워크에 접속하는 조건을 시뮬레이션합니다. 하위 PC의 MAC 주소를 GMS로 전달하는 LECard의 기본 기능과 PC의 패킷 생성 기능을 시뮬레이터에서 구현합니다. 이더넷 패킷은 다중화 인터페이스의 모든 포트로 전송됩니다. 실험 시스템의 MBR 처리량은 시뮬레이터와 이더넷 패킷을 전송하여 평가되었습니다. 결과는 MBR 패키지의 처리 속도가 약 4000PPS임을 보여줍니다. 또한 사용자 포트 성능 저하가 활성 비율의 약 20%, 즉 동시에 액세스하는 사용자의 20%까지 약간 있음을 보여줍니다.

Abstract: We have already proposed a regional PC communication network system that provides a LAN environment and group communication services to the customers. A Low-end Card (LECard) is set up in the subscriber's household and provides the popular Ethernet interface (10Base-T). A multiplex-port brouter (MBR) was developed to accommodate a lot of customers in a cost-effective manner. Ethernet packets are transferred through each subscriber channel between the LECard and the MBR using the HDLC protocol. The LECard and the MBR are controlled by the group management server (GMS) to realize the group communication system. The performance of an experimental system in ordinary use must be evaluated before bringing the system into practical use. However, it is difficult to prepare a number of PCs and to use them at the same time to evaluate the performance degradation seen in multiple-access. This paper presents a newly developed multiple-access simulator for evaluating MBR performance. The simulator connects to the MBR under test through a multiplexed signal interface. It simulates the conditions in which many LECards and PCs are connected to an MBR and they access the network at the same time. The basic function of the LECard, passing the MAC addresses of subordinate PCs to GMS, and the packet generating function of the PCs are implemented in the simulator. Ethernet packets are transmitted to all ports of the multiplexed interface. MBR throughput in the experimental system was evaluated by transmitting Ethernet packets from/to the simulator. The results show that the MBR package has a processing speed of about 4000 PPS. They also show that the degradation in user port performance is slight up to approximately 20% of the active ratio, i. e. 20% of the users access at the same time.
