VERFAHREN ZUM MULTIPLEXEN VON VIRTUELLEN KANÄLEN AUF EINE ÜBERTRAGUNGSLEITUNG

摘要

The object in packet switching systems is to interleave the cell streams intended for a number of receivers in time on a single transmission line (LE). This multiplexing is carried out with the aid of a distribution table which contains entries which show when a cell (ZE2) for a receiver is to be transmitted. The number of entries corresponds to the aggregate data rate of the transmission line (LE) and the entries are allocated to the receivers in accordance with the data rate of these receivers. An appropriate choice of the distribution of the cells to the output cell stream has the result that no conflicts can occur when the cells are multiplexed onto the transmission line. The distribution table is processed cyclically at the cell clock rate and, during this process, a cell which corresponds to the receiver specified in the entry is selected in accordance with the entry.
