| 摘要 |
The invention relates to a multiple access communication method in a system including a central unit (10) and a plurality of peripheral units (20-20) connected to said central unit (10) through a first monodirectional connection means (70) adapted to realize the transmission of fixed length data packets from said central unit (10) towards said peripheral units (20-20) and through a second monodirectional connection means (60) adapted to implement the transmission of fixed length data packets from said peripheral units (20-20) towards said central unit (10). The invention foresees a step to insert in said packet transmitted on said first connection means (70) a field containing the information of a first Bundle Flow Identifier (BFI), identifying a bundle of a plurality of Virtual Paths (VP) coming out downstream (downstream) from a same peripheral unit (20). The invention also foresees a step to insert in said packet transmitted on said second connection means (60) a field containing the information of a second Bundle Flow Identifier (BFI), identifying a bundle of a plurality of Virtual Paths (VP) entering upstream (upstream) a same peripheral unit (20). Thanks to the above-mentioned identifiers, it is possible to control the cells, processing the same in a unique central point. |
