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.
