<p>The invention concerns a method for translating an ATM switch cell header to be routed in a communication network transmission route via an ATM switch, the cell header comprising a first VPI field and a second VCI field, the first VPI field identifying the virtual path number and the second VCI field selecting a virtual channel, consisting in: storing in a first major table (3) the indirection context page numbers; storing in a second major table (4) context page numbers for the circuits in VP switching mode; storing in the indirection (5) context pages (2) context page numbers (7) for the circuits in VC switching mode; addressing via one indirection (5) context page (7) context pages (7) of circuits in VC switching mode on the basis of the first major table (3) and the VCI field; and addressing the context pages (9) of the VP switching mode on the basis of the context page numbers contained in the second major table (4). The invention is applicable to ATM switch.</p> |
