Abstract

La invencion se refiere a un método de comunicacion de acceso multiple en un sistema que comprende una unidad centralizada y una multiplicidad deunidades periféricas conectadas a dicha unidad centralizada mediante un primer medio de conexionmo nodireccional apto para realizar la transmision depaquetes de datos de longitud fija desde dicha unidad centralizada hacia dichas unidades periféricas y mediante un segundo medio de conexion monodireccionalapto para realizar la transmision depaquete s de datos de longitud fija desde dichas unidades periféricas hacia dicha unidad centralizada. La invencion prevéla fase de insertar en dicho paquete transmitido sobre dicho primer medio de conexion un campo que contiene lasinformaciones de un primer identificador deFlujo Agrupado (BFI), el cual identifica una agrupacion de una multiplicidad de Recorridos Virtuales (VP) egresante corriente abajo (downstream) desde unamisma unidad periférica. La invencion prevétambién la fase de inserta r en dicho paquete transmitido sobre dicho segundo medio de conexion un campo quecontiene las informaciones de un segundo identificador de Flujo Agrupado (BFI), el cual identifica una agrupacion de una multiplicidadde Recorridos Virtuales(VP) q ue ingresan corriente arriba (upstream) en una misma unidad periférica. Gracias a dichos identificadores es posible gestionar las células elaborándolasen un unico punto centralizado.The invention relates to a multiple access communication method in a system comprising a centralized unit and a multiplicity of peripheral units connected to said centralized unit by means of a first non-directional non-directional connection means capable of transmitting fixed-length data packets from said centralized unit towards said peripheral units and by means of a second monodirectional connection means to carry out the transmission of fixed-length data packages from said peripheral units to said centralized unit. The invention provides for the phase of inserting in said packet transmitted on said first connection means a field containing the information of a first grouped flow identifier (BFI), which identifies a grouping of a multiplicity of Virtual Routes (VP) downstream downstream ) from the same peripheral unit. The invention also foresees the phase of inserting r in said packet transmitted on said second connection means a field that contains the information of a second grouped flow identifier (BFI), which identifies a grouping of a multiplicity of Virtual Tours (VP) that enter upstream in the same peripheral unit. Thanks to these identifiers it is possible to manage the cells by preparing them in a single centralized point.
