Parallel switching in multistage systems

In the paper, the problems of design of the parallel space switching systems is considered. The shortcomings of crossbar switches are analyzed as well as the possibilities of design of parallel switching in multistage systems. There is also a description of the structure of parallel cross switch, which is the basic one in building the ladder circuits. The structure of the switching elements of the parallel space switching systems is described as well. The parallel space switching systems based on such switch cabins will allow to reduce the connection time and losses caused by the congestion of the general control unit.

I. Introduction

Switching elements are the integral part of the most various information systems, such as multiprocessing systems, multinuclear processors, neural processors, and telecommunication networks. As a rule, in such devices there is a necessity for construction of the effective communication media providing data exchange between various parts of such device. It is possible to raise efficiency of communications due various switching means. However, efficiency of communications will depend on productivity of switching system. Many papers are devoted to increase of productivity of switching systems. Unfortunately, as a rule it cover the technological aspects of the problem: improvement of the know-how of integrated switchboards. It this paper, we propose another approach for increase of productivity of the switching systems that consists of parallel process of connections establishment.
