Cet article étudie l'efficacité d'un réseau qui utilise un débit binaire non spécifié (UBR) pour un canal virtuel (VC) prenant en charge les connexions AAL2. AAL2 est une nouvelle couche d'adaptation ATM qui a été récemment normalisée. Puisqu'il est conçu pour transporter efficacement des signaux vocaux à faible débit, il devrait être utilisé dans le réseau fédérateur ATM des réseaux mobiles, en particulier dans le réseau IMT-2000 (réseau international de télécommunications mobiles à l'an 2000). Normalement, des VC à débit binaire constant (CBR) ou à débit binaire variable (VBR) sont utilisés pour prendre en charge les connexions AAL2. Cependant, dans nos travaux précédents, nous avons montré que l'utilisation de VC UBR (équivalent à aucune gestion de bande passante au niveau VC) pour prendre en charge les connexions AAL2 nécessite beaucoup moins de bande passante VP que l'utilisation de VC CBR ou VBR. Dans cet article, les résultats précédents sont étendus au réseau et la réduction de la bande passante du réseau s'avère plus importante que celle du chemin virtuel. De plus, la réduction de bande passante obtenue grâce à l'utilisation des VC UBR est comparable à celle obtenue en introduisant des nœuds de commutation AAL2. Sur la base de ces résultats, le réseau central des IMT-2000 est discuté.

Abstract: This paper investigates the effectiveness of a network that uses unspecified bit rate (UBR) for a virtual channel (VC) accommodating AAL2 connections. AAL2 is a new ATM adaptation layer that has recently been standardized. Since it is designed to carry low-bit-rate voice signals efficiently, it should be used in the ATM backbone for mobile networks, especially in the IMT-2000 network (International Mobile Telecommunication in the Year 2000 network). Normally, constant-bit-rate (CBR) VCs or variable-bit-rate (VBR) VCs are used to accommodate AAL2 connections. In our previous work, however, we showed that using UBR VCs (equivalent to no VC-level bandwidth management) to accommodate AAL2 connections needs much less VP bandwidth than using CBR or VBR VCs. In this paper, the previous results are extended to the network and the network bandwidth reduction is shown to be larger than that of the virtual path. In addition, the bandwidth reduction achieved by using UBR VCs is comparable with that achieved by introducing AAL2 switching nodes. Based on these results, the core network of the IMT-2000 is discussed.
