Nous avons déjà proposé un système de réseau de communication PC régional qui fournit un environnement LAN et des services de communication de groupe aux clients. Une carte bas de gamme (LECard) est installée chez l'abonné et fournit l'interface Ethernet populaire (10Base-T). Un routeur à ports multiplex (MBR) a été développé pour accueillir un grand nombre de clients de manière rentable. Les paquets Ethernet sont transférés via chaque canal d'abonné entre la LECard et le MBR à l'aide du protocole HDLC. La LECard et le MBR sont contrôlés par le serveur de gestion de groupe (GMS) pour réaliser le système de communication de groupe. Les performances d'un système expérimental en utilisation normale doivent être évaluées avant de mettre le système en pratique. Cependant, il est difficile de préparer plusieurs PC et de les utiliser en même temps pour évaluer la dégradation des performances constatée en accès multiple. Cet article présente un simulateur à accès multiple nouvellement développé pour évaluer les performances du MBR. Le simulateur se connecte au MBR testé via une interface de signal multiplexé. Il simule les conditions dans lesquelles de nombreuses LECards et PC sont connectés à un MBR et accèdent au réseau en même temps. La fonction de base de la LECard, à savoir la transmission des adresses MAC des PC subordonnés au GMS, et la fonction de génération de paquets des PC sont implémentées dans le simulateur. Les paquets Ethernet sont transmis à tous les ports de l'interface multiplexée. Le débit MBR dans le système expérimental a été évalué en transmettant des paquets Ethernet depuis/vers le simulateur. Les résultats montrent que le package MBR a une vitesse de traitement d'environ 4000 20 PPS. Ils montrent également que la dégradation des performances des ports utilisateurs est légère jusqu'à environ 20 % du taux actif, soit XNUMX % des utilisateurs accédant en même temps.

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.
