METHOD FOR TRANSLATING AN ATM SWITCH CELL HEADER |
摘要 |
The invention relates to a process for translating an ATM cell header for the routing thereof on a transmission highway of a communication network via an ATM switch. The header of the cell includes a first field VPI and a second field VCI, the first field VPI identifying a virtual path number and the second field VCI selecting a specified virtual channel within the virtual path. The process includes storing indirect addressing context page numbers in a first major table (3), storing context page numbers for the circuits in VP switching mode in a second major table (4), storing context page numbers (7) for the circuits in VC switching mode in indirect addressing (5) context pages (2), addressing the context pages (7) of circuits in VC switching mode by way of an indirect addressing (5) context page on the basis of the first major table (3) and of the field VCI, and addressing the context pages (9) of the VP switching mode on the basis of context page numbers contained in the second major table (4). |
