چکیده

In this paper, we present a model for computing the cost of implementing Banyan networks. We limit our interest in Banyan networks which are used in ATM switching fabrics and are build in VLSI. The cost is given as a function of the characteristics of the network (i.e. length of buffers, speed of links, etc.). It is well-known that the implementation cost must be related to the performance of the network. The choices, that the designer may have, impact both the performance and the cost. We demonstrate the case where a slight increase in performance implies a great increase in cost (in that case it is not cost effective to build a better switching network), and of course the reverse, i.e., the case where a decrease in cost implies a degradation of the performance of the switch. RÉSUMÉ. En cet article, nous présentons un modèle pour calculer le coût de mettre en application des réseaux Banyan. Nous limitons notre intérêt pour les réseaux Banyan qui sont utilisés dans des ATM tissus de commutation et sont construits avec VLSI. Le coût est indiqué en fonction des caractéristiques du réseau (c’ est à dire, du longueur des mémoires tampons, de la vitesse des liens, etc.). Il est bien connu que le coût de mettre en application doive dépendre de l’efficacité du réseau. Les choix, cela que le créateur peut avoir, effectue l’efficacité et le coût. Nous montrerons le cas où une légère augmentation d’efficacité implique une grande augmentation de coût (dans ce cas il n’est pas rentable pour établir un meilleur réseau de commutation), et, bien sûr, l’inverse, c’ est à dire le cas où une diminution en coût implique une dégradation de l’efficacité du commutateur.

Cost/Performance evaluation of Banyan networks for use in ATM switching fabrics

In this paper, we present a model for computing the cost of implementing Banyan networks. We limit our interest in Banyan networks which are used in ATM switching fabrics and are build in VLSI. The cost is given as a function of the characteristics of the network (ie. length of bu ers, speed of links, etc). We are focusing in this area because such networks have been used extensively in the des...

Reducing cell loss in banyan based ATM switching fabrics

In this paper, we propose a new technique for reducing cell loss in multi-banyan based ATM switching fabrics. We propose a switch architecture that uses incremental path reservation based on previously established connections. Path reservation is carried out sequentially within each banyan but multiple banyan planes can be concurrently reserved. We use a conflict resolution approach according t...

A scalable family of high-speed switch architectures

In this paper we present a scalable and recursive class of banyan switching architectures called the Shared-Tree Banyan Networks (STBN). For ATM networks STBN can be engineered between two extremes: (1) a low-cost banyan with internal and external conflicts, or (2) a high-cost conflict-free fully-connected network with multiple outlets. STBN scalability is based on: (1) scalable concentrator ba...

Fault tolerance of the TBSF (Tandem Banyan Switching Fabrics) and PBSF (Piled Banyan Switching Fabrics)

Multistage Interconnection Networks (MIN) with multiple outlets are networks which can support higher bandwidth than those of nonblocking networks by passing multiple packets to the same destination. Fault recovery mechanisms are proposed for two of such networks (TBSF/PBSF) with the best use of their inherent fault tolerant capability. With these mechanisms, on-the-fly fault recovery is possib...

Performance Evaluation of a Modified Cyclic Banyan based ATM Switch for B-ISDN

This paper focuses on designing a Fast Packet ATM switch suitable for B-ISDN. It is a Banyan network using cyclic interconnection among switching elements of the same stage for deflection routing. The proposed routing is as simple as that of the generic Banyan network, and all the switching elements (SE’s) have a uniform structure. To design the proposed network and to develop its self-routing ...
